# Release notes

## 1.10
New features:
* Added "Paste Preceding Line" in the input prompt dialog. Potential use cases include user-editable sections on a page and suggested/example input values.
* Identity toolbar menu can be used to switch between alternate identities. If you have used multiple identities on one site, this makes it more convenient to switch between them.
* Added option to disable cursor blinking in input fields.
* UI language for Dutch.

Changes and enhancements:
* Inline image metadata goes under the image instead of possibly overlapping the image caption text.
* Improved apperance of opened links highlighting. It no longer goes under the side elements on the page.
* Revised layout of the Upload dialog. There is a new edit field that lets you modify the file path of the URL. Identity names are in bold.
* Optimized UI layout procedure and memory use during UI event processing.
* Audio subsystem is only initialized when actually needed.
* Prevent state file corruption if the app happens to get killed while state is being saved.
* Gempub: Open books in 1:2 split mode instead of 1:1.
* Minor improvements in page caching.

Fixes:
* Fixed a history caching issue: if there were multiple instances of the same URL in history, only the latest one's content would be used when navigating back/forward.
* Fixed very narrow input fields causing the app to hang.
* Fixed initial scroll position in multiline input fields.
* Fixed lookup results list becoming too narrow.

## 1.9.2
* Windows: Use the correct version number for update checks.
* Shorter label for "Mark All as Read" in Feeds sidebar actions.
* Updated UI translations.

## 1.9.1
* Added "24-Hour Time" preference. Currently it only affects the page timestamp in the bottom left corner.
* Heading level 3 is indented like regular text lines, making the difference to level 2 evident.
* Fixed crash when creating a top-level bookmark.
* Fixed drawing the page timestamp.
* Fixed layout of tab buttons and other resizing widgets so all available space is used.
* Fixed tab close buttons preventing activation of very short tab buttons. The close buttons only appear if there is room for them.
* Fixed very short tab labels not getting truncated.
* Fixed the New Tab button not staying at the right edge of the window, depending on how many tabs are open.

## 1.9
New features:
* Added a toolbar button for toggling the left sidebar.
* Added an unsplit button in the toolbar when in split view mode.
* Choose parent folder when creating or editing a bookmark.
* Support for 24-bit RGB ANSI color sequences.
* Support for ANSI background color escapes (disabled by default).
* macOS: Automatic updates using the Sparkle framework.
* Windows: Automatic updates using the WinSparkle library.
* UI language for Turkish.

Changes and enhancements:
* Adjusted font styles of heading levels 2 and 3.
* Sidebar context menus also appear when clicking over the sidebar background. In this case the menu contains general functions not related to any item.
* Feeds tab in the sidebar has a redesigned action toolbar with "Mark All as Read", and dropdown menu and keyboard shortcuts for changing the filter mode.
* Feeds tab remembers the unread/all filter mode persistently.
* ANSI foreground colors are modified to match colored theme backgrounds (e.g., Sepia).
* Navigating back and forward in history will skip input query prompts (status 1x), showing only the query results. 
* Ctrl+A now selects all text in input fields (except on macOS, where it remains the Emacs-style jump to start/end of line).
* The resource bundle (resources.lgr) is now a regular ZIP archive. This allows it to do double duty as a fontpack containing the built-in fonts. The archive contains a version number to avoid use of obsolete resources.

Fixes:
* Fixed layout issues related to footer action buttons. Sometimes the buttons would overlap page content.
* Fixed handling duplicate feed entries: if multiple entries in a feed have the same URL, only use the first one.

## 1.8.3
* Fixed clicking on UI elements that are over the page top banner. The banner would always get clicked instead.
* Titan upload identity is remembered as a site-specific setting. It is no longer affected by selections in the Identities sidebar.
* macOS: Fixed updating items in native menus, e.g., upload identity selection.

## 1.8.2
* Fixed encoding of `+` characters in URLs as per RFC 3986.
* Fixed crash when fontpack.ini specifies a file that cannot be found.
* Fixed incorrect title of some error messages (was showing response meta info).
* Fixed ambiguous font dropdown menu items if some fonts have the same name. Now the unique font ID will be included in these cases.
* Made it possible to manually trust a certificate whose subject doesn't match domain name.
* Updated UI translations.

## 1.8.1
* Added UI translations: Hungarian, Czech.
* Added the `zip` utility as a build requirement. It is used for making fontpacks.
* Fixed build failure with the simple text renderer, i.e., when HarfBuzz is disabled.
* Fixed issues scrolling tall popup menus (e.g., UI language selection).
* Fixed a line spacing artifact in long headings. With some fonts, the lines were clipping each other so the spacing was restored to normal.
* Fixed a socket I/O issue that caused received data to be ignored when the peer closed the connection prematurely.
* macOS: Tab close buttons are on the left side (platform UI convention).
* Gopher: Recognize both LF and CRLF line endings in page content.

## 1.8
⚠️ Font settings will be reset to defaults. Only a minimal set of fonts is bundled with the app. If additional fonts are needed, one can use custom TrueType fonts or download some from the Font Library:
=> gemini://skyjake.fi/fonts/

New features:
* Added a customizable font library. Open "about:fonts" to view and manage the installed fonts.
* Added TrueType fonts as a recognized content type. When one is viewed in the app (e.g., via a drag-and-drop), there is an option to install it as a user font.
* Added fontpacks: ZIP archives containing one or more TrueType fonts and parameters about how they should be used.
* Added support for TrueType collections (.ttc).
* Added new font options: separate preformatted and monospace body fonts, UI font, smoothing.
* Added style option to show all links as bold regardless of visited status.
* Added warning message about missing font glyphs.
* Added warning message about terminal emulation. Lagrange supports a small subset of ANSI escape sequences, so page appearance may be incorrect when these are used in content.
* Added tab close buttons.
* Added a feed subscription option to exclude web links (HTTP/HTTPS), since those are not viewable in the app by default. 
* Added an automatic conversion of Markdown to Gemtext when viewing local files. (Not all Markdown features are supported.)
* Added UI language for Ukrainian (uk).

Changes and enhancements:
* Removed all alternative built-in content fonts.
* The default content font is Source Sans, same as the UI font.
* Redesigned error/warning messages. These now show up as part of the page top banner, and their appearance can no longer be replicated via Gemtext.
* Warning messages are interactive. Click on them to perform relevant actions.
* Per-pixel scrolling in input fields (e.g., when using a trackpad on macOS).
* "file://" pages are always unthemed.
* Show a byte counter during large downloads instead of instantly jumping to a content view. Content may not viewable correctly until the download has finished.
* Site-specific settings (sitespec.txt) converted to .ini format. These are currently used for the Titan upload port and remembering which warnings have been dismissed.
* macOS: One can choose between Black/Dark and Light/White UI palette when system color theme is enabled. Previously the system theme always switched to either Dark or Light.

Fixes:
* Fixed an issue where the page is unscrollable until the mouse cursor is moved (wrong hover state).
* Fixed wrapping of long input prompts and dialog messages.
* Titan upload token is remembered when the dialog is closed.
* Fixed various layout issues with page footer buttons.
* Fixed theme change glitches when an input prompt appears.
* macOS: Fixed forced unhiding of the dock when the app is launched.

## 1.7.3
* Fixed a memory leak in the text renderer.
* Added option to place new bookmarks to the top of the bookmarks list.
* Updated UI translations.

## 1.7.2
* Fixed regressions in text selection, for example when marking text leftwards from the start position or when starting from outside any text run. 
* Fixed a crash when clicking on Outline sidebar items before a page has finished loading.
* Gopher: Handle the `p` line type (PNG image).

## 1.7.1
* Fixed feed entries forgetting their (un)read status after several months.
* Fixed feed entries being discarded before they are removed from their source feed, causing them to reappear on the next refresh.
* Fixed failure to parse Atom feed entry timestamps that use space as the date/time separator.
* Fixed dropdown labels staying visible in the translation dialog.
* Fixed showing/hiding of the feed update indicator in split view.
* Fixed a crash when selecting text.
* Added a small progress bar to the feed update indicator.
* When adding a bookmark/folder, the bookmarks list scrolls to show the new item.
* Improved reordering bookmarks in a folder: an item inside a folder can be moved to be the last item in the folder, or out of the folder depending on which side of the boundary marker the mouse cursor is.

## 1.7
⚠️ Bookmarks file format has changed. Your existing bookmarks will be imported to the new format. The old bookmarks.txt file can be found in the config directory and is writable only by v1.6 and earlier versions.
⚠️ Saved UI state format has changed. Downgrading will reset window state, close all tabs, and clear the navigation cache.

New features:
* Added bookmark folders. Folders can be nested inside each other, and the fold state of each folder is remembered persistently (per sidebar).
* The Bookmarks export/list page uses subheadings (level 2 and 3) to represent folders.
* Added menu item to sort (a folder of) bookmarks alphabetically.
* Added identity selection in the Upload dialog.
* Added image colorization setting. Images can be viewed in grayscale or using the page's theme colors.
* Added UI focus cycling to all buttons with Tab and Shift+Tab. This includes dialog buttons and the navigation bar.
* Added a footer action to view `application/octet-stream` content depending on recognized file extensions.
* Added support for viewing WebP images. The libwebp library is an optional dependency and will be included in the build if found via pkg-config.
* Added command line options -w, -h for setting window size at launch.
* Added new UI languages: Esperanto, Spanish (Mexico), Galician, Interslavic, and Slovak. Note that some of these are still works in progress.

Changes and enhancements:
* Bookmarks are now ordered manually. You can drag and drop bookmarks in the list to change the order.
* The internal bookmarks file format is now a TOML subset instead of just being three text lines per bookmark, making it more robust and human-readable.
* Context menus and other popup menus that do not fit inside the window are split off into independent windows.
* macOS: Use native UI controls for context/popup menus. Note that this required making a couple of small changes to SDL (see the updated patch in the repository).
* Dropdown button menus position themselves on the currently selected item.
* Dialogs that don't fit inside the window have a scroll bar. Note that such dialogs can only be scrolled via mouse wheel/trackpad, not by dragging the bar.
* Adjusted mouse wheel smooth scrolling speed for better consistency. The default scrolling speeds were increased to level 2.
* Visited URLs are remembered for six months. This affects the unread status of feed entries and the visited status of links.
* Adjusted the UI color palette so that the alternative accent color is used more rarely. For example, input fields now use the primary accent color.
* Adjusted button hover/press colors for better consistency, particularly when the button label uses a non-standard color.
* Image links (as determined by file extension) automatically use a "photo" link icon if the URL is on the current site. This makes it clearer which links will likely show up as an inline image.
* Alt+Shift+Tab inserts a tab character in input fields.
* UI rendering optimizations. Some UI controls (e.g., navbar, menus) will buffer their contents so they can be drawn efficiently during animations.

Fixes:
* Fixed issues with subscribed feed entry tracking. Heading entries are not discarded until they are removed from the source.
* Fixed the sidebar unread entry count showing the wrong number after subscribing to a Headings feed.
* Fixed handling of tab characters in the Upload text editor (when using HarfBuzz).
* Fixed hang when wrapping a very long word (with HarfBuzz disabled).
* Fixed regressions in retaining window state, position, and size.
* Fixed URL encoding of the % character.
* Fixed ambiguous handling of colons in URI paths.
* Fixed issues with cursor positioning in multi-line input fields.
* Fixed issues with touch swipe events.
* X11: Ask SDL not to bypass the window compositor. This should avoid issues on KDE, for example.
* macOS: Fixed a flash of blank background color when launching the app.
* Windows: The main window title bar (when not using a custom frame) uses dark mode colors according to the UI color theme setting. Previously it was always stuck on light mode.

## 1.6.5
* Audio init errors are no longer fatal. SDL's error message will still be printed.
* Fixed appearance of tab buttons (should have no top frame).
* Fixed a cursor position regression in input fields related to handling of variation selectors (codepoint clusters). Moving the cursor to the start of a wrapped line segment put the cursor in the wrong place.
* Fixed right-clicking on sidebar tab buttons. It was showing the wrong context menu when the list had been scrolled down.
* Fixed crash when using the SDL2 KMSDRM video driver.
* Fixed minor visual artifacts in preformatted blocks and near the bottom of the page.

## 1.6.4
* Local files containing UTF-8 text can be viewed regardless of their file extension.
* Fixed input field cursor positioning and insertion problems around Emoji variation selectors.
* Fixed "Unknown Status Code" shown in Page Information for valid status codes.
* Fixed an issue with network requests that would make it appear the server was not responding, but the request would not time out.
* Fixed a potential invalid memory access when clicking on sidebar items.
* OpenBSD: Fixed a freeze after a network request is cancelled.
* Fixed page contents not reflowing during a window resize.
* Added build option ENABLE_RESIZE_DRAW. SDL doesn't redraw window contents on all platforms during resizing, so this can be used to force it.

## 1.6.3
* Select all text in an input field using Shift+Ctrl+A (macOS: ⌘A).
* Input fields do not lose focus when the window becomes inactive, making it easier to resume input afterwards.
* Fixed delay after switching to split view mode.
* Fixed what gets drawn in an empty tab, before a document is available for rendering (e.g., after switching to split view mode).
* Fixed highlighting the domain name in URL input fields.
* Fixed hiding the Gemini URL scheme in input fields when the window is narrow.
* Fixed the line break key modifier inadvertently affecting URL input fields, where line breaks are not allowed.
* Fixed the line break key modifier affecting the upload dialog's text field.
* Fixed a potential hang when closing a socket before the connection is fully opened.
* Updated translations.

## 1.6.2
* Added `--tab-url` to print currently active tab's URL.
* Upload dialog expands to full window height when the entered text is long.
* Home/End keys in an input field move to start/end of the wrapped line segment.
* Scroll with mouse wheel in input fields.
* Slower cursor blink rate in input fields.
* Adjusted dark mode colors for focused input fields.
* Fixed incorrect behavior in input fields when typing or deleting text while holding down the Shift key.
* Fixed crash in Upload dialog if server responds with a redirect.
* Fixed buffered graphics (UI, fonts) getting lost under rare circumstances.
* Fixed drawing of wrapped text when the app is compiled without HarfBuzz.
* macOS: Fixed UI not updating when system dark mode is toggled while the window is hidden.

## 1.6.1
* Fixed potential crash when inserting a line break in an input field.
* Fixed cursor positioning in fixed-length input fields.
* Fixed copying text in input fields (the wrong region was copied).
* Fixed URL input field contents not being selected after opening a new tab.
* Fixed Upload dialog not showing when reloading a Titan URL.
* Updated translations.

## 1.6
⚠️ A new TOFU trust store will be created. The old one is kept around but ignored.
⚠️ App state serialization format has been updated. Downgrading to a previous release will cause app state to be reset (e.g., tabs closed, navigation history cleared).
⚠️ New build dependencies: HarfBuzz and GNU FriBidi (see README).

New features:
* Added support for bidirectional text and complex scripts. العالم متنوع
* Right-to-left paragraphs are aligned to the right. Link icons and list/quote symbols are moved to the right margin.
* Added support for Titan uploads. The data to upload can be entered via a text field or by dropping a file on the window.
* Added a keybinding for opening the current page URL in the upload dialog (Ctrl+U/⌘U). This simply switches the page's URL scheme from `gemini` to `titan`.
* Added a configuration file for defining the UI color palette (see Help, section 3.5).
* Added settings for keyboard and mouse scrolling speeds.
* Added setting for changing Return key behavior in input fields (line break vs. accept).
* Added setting for adjusting line spacing.
* Added link context menu item for deleting local files (e.g., downloads).

Changes and enhancements:
* Improved TOFU: if the server certificate is not trusted, the connection is aborted at the TLS handshake stage. Previously, only a warning was shown and the page contents were fetched regardless.
* Server certificate fingerprints are generated based on public keys, which allows servers to renew their certificates without losing trusted status.
* Improved handling of expired server certificates. An error page is shown and the connection is aborted at the TLS handshake stage. The user can give a temporary exception to load the page.
* Page contents are cached in presentation form for quicker restoring during back/forward navigation.
* Inline images/audio will not get discarded during back/forward navigation. The Network > Memory Size setting determines the maximum memory usage for media. Setting the Memory Size to zero is equivalent to the previous behavior of discarding everything when the page changes.
* Debug information includes RAM use in addition to cache size. This includes document layout and media stored in memory (e.g., raw pixel data of images).
* Text input fields support larger amounts of content and expand vertically only up to a limit, after which they start scrolling.
* Preferences have been reorganized. There is a new Fonts tab, and some General settings have been moved to the Style tab. All color-related settings are on the Colors tab, including UI theme colors.
* Links opened on a page are updated to reflect visited status even when opening into a background tab or to the side.
* Unicode Byte Order Mark is ignored in the beginning of a page.
* Updated Smol Emoji with new characters.
* Query/Feeds indicators have a smaller appearance in a narrow window to leave room for the URL.

Fixes:
* Large lede paragraph font is not applied if the paragraph has too many lines.
* Fixed minor kerning issues when using Nunito.
* Fixed sizing of characters in the Noto Symbols fonts.
* Improved internal handling of URLs. For example, some URLs were not being recognized as visited because of percent-encoding differences.
* Fixed URL in the generated page for viewing a single image (spaces weren't encoded).
* Input dialog is not dismissed unless the Cancel button is clicked or Escape is pressed.
* Workaround for a potential hang during the closing of a socket.
* TLS client certificates generated by the app have identical issuer and subject fields, including all the provided information and not just the Common Name.
* Gopher: Improved detection of ASCII art.
* Gopher: Show contents of unrecognized line types.
* Gopher: Don't collapse preformatted blocks since everything is preformatted in the source.
* Gopher: All preformatted blocks are unindented to avoid misaligned ASCII art.
* macOS: ^⌘Space shows the system-provided symbols and Emoji character palette.

## 1.5.2
* Fixed pasting a PEM-formatted certificate and/or private key via clipboard in Import Identity.
* Possible workaround for a visual glitch in the URL field.
* Specify `StartupWMClass` in .desktop file.
* Normalize page contents to avoid the most common issues with diacritics (Unicode NFC).
* Expanded the set of recognized custom link icons.
* Updated "Smol Emoji" font with new glyphs.
* Allow use of TLS cipher "DHE-RSA-AES256-GCM-SHA384".

## 1.5.1
* Updated UI translations.
* Updated "Smol Emoji" font with new and improved glyphs.

## 1.5
* Added "Smol Emoji" and "Noto Sans Symbols" fonts, removed Symbola.
⚠️ Many Emoji and pictographs defined in the last five years are currently missing.
* Added document footer buttons: on certain pages (e.g., error messages) show relevant actions in the bottom of the page. For example, if a certificate is required for viewing a page, show buttons for creating a new identity and showing the Identities sidebar.
* Error pages include the human-readable text sent by the server.
* Disregard old feed entries whose unread status would have been forgotten.
* Added UI language: Polish.

Identity management:
* Revised New Identity dialog. An option is provided to automatically use the new identity on the current domain/page. The additional fields are hidden by default.
* Improved usability of Identities sidebar. No more accidental activations: left-clicking an identity opens the context menu without making any changes. The context menu shows each active URL as a menu item for easy access. Identity icons reflect the usage status: all identities used on the current domain get highlighted in addition to the currently used one.
* Identities can be exported: certificate and private key are opened in a new tab in plain text PEM format.
* Fixed issues with identity usage: a higher-up URL overrides and deactivates all contained URLs to avoid redundant activation.

Text input:
* Revised text input widgets: added support for multiple lines, and when entering user response to a query, show how many bytes are remaining for the response URL about to be submitted. In dialogs, input fields expand vertically instead of scrolling their content horizontally.
* Input widgets allow inserting newlines using Shift+Return.
* Disallow sending query responses that are too long (1024 bytes maximum).
* Shift-click to select a range of text in input widgets (i.e, without dragging).

Rendering:
* Animate showing and hiding of sidebars and dialogs. Animations are enabled by default, by can be disabled with Preferences > Interface > Animations.
* Added setting for a custom TrueType symbol font for any missing characters. Note: Must be a .TTF file — OpenType and bitmap fonts are not supported.
* Link navigation shortcut icons (home row and numbered) are drawn with a consistent appearance.
* Improved icon alignment in lists.
* Reduced line gap between word-wrapped top-level headings.
* Modal dialog background dimming fades in/out smoothly.
* macOS: Workaround for an issue that causes UI refresh to pause occasionally for ~100 ms.

Split view:
* Added keybindings for split view menu items.
* Changed default split view keys to conform to Emacs (3 for horizontal, 2 for vertical split).
* Fixes and improvements for touch screen event handling in split view mode.

Command line:
* Added --url-or-search (-u) command line option. Depending on the parameter, either open an URL or make a search query.
* Open all URLs/files specified on the command line in new tabs, and raise the window if the app is already running. (Kudos to Alyssa Rosenzweig.)

Gempub:
* Linear navigation through the book with Left/Right arrow keys and via footer buttons. The navigation order is determined by links on the Gempub index page.

## 1.4.2
* Fixed UI colors being all black on the first run.
* Fixed right mouse click on an inactive split not having any effect.
* Fixed action buttons showing under the Help link in an empty Identities sidebar.
* Fixed potential crash at shutdown.
* Fixed minor UI layout issues.

## 1.4.1
* Fixed removing the left side split by closing all its tabs. The URL input field got confused about which tab was currently open, and the wrong theme was active.
* Fixed tab merging when unsplitting the window: keep the currently active tab open.
* Fixed issue with sidebars sometimes becoming unresponsive.
* Fixed font used for visited monospace Gopher links.
* Fixed incorrectly shown/hidden ◧ indicator.
* Fixed scrollbar in Preferences > Keys being hidden until the list is scrolled.

## 1.4
* Added split view modes: two tabs at once, horizontal/vertical split, 1:1/2:1/1:2 weights, merge tabs, swap sides. See section 1.8 in Help for details.
* Split view pinning: keep a page pinned on one side while all opened links go to the other side.
* "file://" URLs can be used for viewing contents of local directories and ZIP archives.
* Basic Gempub support: a cover page is generated based on metadata, and there's an automatic split view for index and contents. On macOS, Lagrange is registered as a viewer of .gpub files.
* Bold link styling is used for indicating which links are unvisited.
* Page rendering was optimized: now each line of text is rendered into the view buffer only once, and whenever the view is stationary, content is prefilled in the available space outside the viewport. Previously, at least one line of text was rendered every frame when the viewport was moving, which was mostly redundant.
* Added UI languages: Interlingua, Toki Pona.
* Added "New"/"Import" buttons in the bottom of the Identities tab.
* Added an "All"/"Unread" mode switch in the bottom of the Feeds tab.
* Added toggles for special tags in the bookmark creation/editor dialog.
* Added "Show Downloads" to the File/main menu.
* Added "Open Downloaded File" to the file save dialog to make it easy to find the local copy of the file.
* Updated the UI font to Source Sans 3. It now has all the styles and weights needed for page rendering, too.
* Added a semibold Fira Sans weight (used for unvisited links).
* Preferences: Reorganized the fonts dropdown menu.
* Changed popup dismiss behavior so that a click outside just dismisses the popup and does not trigger further actions.
* All lists support smooth scrolling.
* Multitouch scrolling: each finger can scroll a different widget.
* Adjustments to how display DPI affects UI scaling.
* Fixed allocation of page rendering buffers. Previously, some buffers may have gone unused or were allocated erroneously to the same position, causing unnecessary work for the page renderer.
* Fixed various issues in the UI layout.
* Fixed parsing URI scheme (limited set of characters allowed).
* Don't percent encode equal signs in URL paths.

## 1.3.4
* Allow server certificates with a `*.tld` subject wildcard.
* Updated the French UI translation.
* Fixed media type check in the audio player. Media types with parameters failed to be recognized.
* Fixed crash after a redirect.
* Fixed a rare issue with handling multiple rapid network requests.
* Fixed a rare situation where a network connection would fail to open.
* Minor stability improvements.

## 1.3.3
* Added UI languages: French, German. (Note that neither is 100% finished yet.)
* Added build option to disable IPC for compatibility reasons.
* Added environment variable LAGRANGE_OVERRIDE_DPI.
* Back/forward navigation buttons are disabled if they have no more pages to switch to.
* Minor UI color tuning.
* Fixed possible crash when closing a tab.
* Fixed possible crash when restoring application state at launch.
* Fixed problems parsing and making requests with literal IPv6 addresses.

## 1.3.2
* Fixed crash after updating from v1.2 due to undefined CA file/path configuration.
* Fixed conflation of pixel ratio and display DPI. Pixel ratio is now always separately detected so mouse events can be correctly positioned. You may find that adjusting the UI scale factor (Preferences > Interface) is necessary after upgrading.
* Fixed sidebar width changing when moving the window to a different display.
* Fixed inability to use Tab in keybindings.
* Fixed opening Gopher URLs via drag-and-drop.
* Fixed "Add bookmark..." on a feed entry.
* Fixed keybindings list not being updated immediately when UI language changes.
* Fixed trimming of link label text when a custom Emoji is used.
* Windows: Fixed maximum window size being restricted to the initial display's size.

## 1.3.1
* Added UI languages: Serbian, Interlingue.
* Added option to disable bold links for light/dark backgrounds.
* Updated the Nunito font to the latest version.
* Fixed crash during word wrapping.
* Fixed keybindings overriding the home row key navigation mode.
* Fixed kerning in the text renderer.
* Fixed issue with overlapped drawing of list bullets vs. list items.
* Fixed cropped list bullets when using Literata.
* Fixed whitespace normalization in plain text files (tab characters).
* Fixed issues buffering window contents, possibly causing missing font glyphs.

## 1.3

Localization:
* Added the first set of UI translations: Chinese (Simplified, Traditional), Finnish, Russian, and Spanish. Many thanks to the translators!
* Added page content translation using a LibreTranslate instance running on `xlt.skyjake.fi`. This is somewhat experimental and may occasionally mess up Gemtext markup. Expect long pages to be quite slow to translate (more than a minute).
=> https://weblate.skyjake.fi/projects/lagrange/ui  Lagrange UI translations (Weblate project)
=> https://libretranslate.com                       More information about LibreTranslate
=> gemini://skyjake.fi/lagrange/privacy.gmi         Lagrange privacy policy

Resources:
* Added Noto Sans CJK (Simplified Chinese) font.
* Added Noto Sans Arabic font. Note that right-to-left/bidirectional text rendering is *not* implemented yet.
* Added "about:about" that lists all the available "about:" pages.

Browsing:
* Alt text is shown when hovering over a preformatted block.
* Clicking on a preformatted block collapses it, leaving only the alt text.
* Added option to collapse all preformatted blocks on page load.
* A server certificate can also be verified by Certificate Authorities. When "CA file" and/or "CA path" are set in Preferences, CA verification will mark a certificate as trusted.
* Relaxed TOFU certificate checking when it comes to domain names: `domain.tld` in a certificate is implicitly considered to also mean `*.domain.tld`.
* Fixed handling of IDNs when the user sets a server certificate as trusted via the UI.
* Fixed handling of unknown URI schemes. Previously they were forcefully converted to absolute URIs, breaking them.

Page content and rendering:
* Color adjustments to the "Colorful Dark", "Colorful Light", and "Gray" themes. "Gray" looks different in dark and light UI modes.
* Spacing of bullet lists vs. link lists is more consistent.
* Links are shown in bold, and tinted with the page theme color for more coherent appearance.
* Custom link icons: Gemini links whose destination is on the same domain use as icon the Emoji or other pictograph at the start of the link label. (For example, see Astrobotany menus.)
* Added option to wrap lines in plain text files. This is on by default because there is no horizontal scrolling for plain text.
* Large images are downscaled to an appropriate size for presentation.
* Improved font glyph caching to reduce stuttering during scrolling. All required glyphs are cached after a page load finishes. This allows more efficient copying of glyphs as the operations can be batched.
* Larger content buffers for scrolling, reducing need to redraw content.
* Gopher: Handling the 'h' line type.
* Fixed minor issues with word wrapping.
* Fixed minor blending artifacts with the current heading shown on the right side of the page.

User interface:
* Improved event handling to support touch screens on any platform (if supported by SDL).
* UI scaling factor is applied immediately when closing Preferences. Restarting is no longer necessary.
* Window rescaled automatically when moving it to a display with a different DPI.
* Added unread feed entry count to the sidebar.
* Added a context menu for toggling sidebars. The menu appears when right-clicking on the navbar or on the sidebar tab buttons.
* Double/triple click selection modes. Double click and drag will select by word, triple click by paragraph.
* Popup menus have icons for items to make it faster to find the item you're looking for.
* Soft shadows for popup menus.
* Scrollbars fade away on macOS/iOS and dim on other platforms.
* Reload button moved into the URL field.
* Narrow URL input fields will not display the default "gemini" scheme.
* Domain name is highlighted in URL fields.
* Added a cut/copy/paste context menu to input fields.
* Added an "Import..." button to the empty Identities sidebar.
* Preferences dialog was partially reorganized for clarity.

* Editable bookmark icons: use your favorite Unicode character as the symbol to represent a bookmarked site.
* Searching via URL field: non-URL text entered in the field is passed onto the configured search query URL (Preferences > Network). An indicator is shown if a query will take place.
* Tab auto-reloading: configure a reloading interval using the page context menu ("Set Auto-Reload..."). Auto-reloading is part of the persistent state of the tab.
* "Iosevka" and "Source Sans Pro" (the UI font) can be used as heading and body fonts.
* User preference for aligning all pages to the top of the window.
* Keybinding (F11) for toggling fullscreen mode. On macOS, the shortcut is ⌃⌘F as before.
