Release notes

- add DisableAntiAlias advanced setting and CmdToggleAntiAlias command
- add CmdShowAnnotations, CmdHideAnnotations, CmdToggleShowAnnotations commands for temporarily hiding / showing annotations
- add CmdToggleInverseSearch to temporarily disable mouse click invoking tex inverse search
- add bgcolor, opacity, textsize, borderWidth arguments to CmdCreateAnnot* commands
- add Annotations.FreeTextBackgroundColor and Annotations.FreeTextOpacity advanced settings
- sort thumbnails on home page by most recently used date. Set advanced setting HomePageSortByFrequentlyRead = true to revert to pre-3.6 behavior of sorting by frequency of use.
- support brotli compression in PDF files
- in Command Palette, if you start search with : we show everything (like in 3.5)
- in Command Palette, when viewing opened files history (#), you can press Delete to remove the entry from history
- improved zooming:
- zooming with pinch touch screen gesture or with ctrl + scroll wheel now zooms around the mouse position and does continuous zoom levels. Used to zoom around top-left corner and progress fixed zoom levels shown in menu
- include manual (F1 to launch browser with documentation)
- add LazyLoading advanced setting, defaults to true. When restoring a session lazy loading delays loading a file until its tab is selected. Makes SumatraPDF startup faster.
- new commands in command palette (Ctrl + K):
- CmdCloseAllTabs : “Close All Tabs”
- CmdCloseTabsToTheLeft : “Close Tabs To The Left”
- CmdDeleteFile: “Delete File”
- CmdToggleFrequentlyRead : “Toggle Frequently Read”
- CmdToggleLinks : “Toggle Show Links”
- CmdInvokeInverseSearch
- CmdMoveTabRight (Ctrl + Shift + PageUp), CmdMoveTabLeft (Ctrl + Shift + PageDown) to move tabs left / right, like in Chrome
- add ability to provide arguments to some commands when creating bindings in Shortcuts:
- CmdCreateAnnot* commands take a color argument, openedit to automatically open edit annotations window when creating an annotation, copytoclipboard to copy selection to clipboard and setcontent to set contents of annotation to selection
- CmdScrollDown, CmdScrollUp : integer argument, how many lines to scroll
- CmdGoToNextPage, CmdGoToPrevPage : integer argument, how many pages to advance
- CmdNextTabSmart, CmdPrevTabSmart (Smart Tab Switch), shortcut: Ctrl + Tab, Ctrl + Shift + Tab
- added UIFontSize advanced setting
- removed TreeFontWeightOffset advanced setting
- increase number of thumbnails on home page from 10 => 30
- add ShowLinks advanced setting and “Toggle Show Links” (CmdToggleLinks) for command palette
- default ReuseInstance setting to true
- added Key arg to ExternalViewers advanced setting (keyboard shortcut)
- added Key arg to SelectionHandlers advanced setting (keyboard shortcut)
- improved scrolling with mouse wheel and touch gestures
- theming improvements
- go back to opening settings file with default .txt editor (notepad most likely)
- don’t exit fullscreen on double-click. must double-click in upper-right corner
- when opening via double-click, if Ctrl is pressed will always open in new tab (vs. activating existing tab)
- register for handling .webp files
- bug fix: Del should not delete an annotation if editing content
- bug fix: re-enable tree view full row select
- change: CmdCreateAnnotHighlight etc. no longer copies selection to clipboard by default. To get that behavior back, you can use copytoclipboard argument instead.
- change: Ctrl + Tab is now CmdNextTabSmart, was CmdNextTab. Ctrl + Shift + Tab is now CmdPrevTabSmart, was CmdPrevTab. You can re-bind it if you prefer old behavior
- CmdCommandPalette takes optional mode argument: @ for tab selection, # for selecting from file history and > for commands.
- command palette no longer shows combined tabs/file history/commands. CmdCommandPalette only shows commands. Because of that removed CmdCommandPaletteNoFiles because now `CmdCommandPalette behaves like it
- removed CmdCommandPaletteOnlyTabs, replaced by CmdCommandPaletteNoFiles @
- Ctrl + Shift + K no longer active, use Ctrl + K. You can restore this shortcut by binding it to CmdCommandPalette > command.
- add Name field for shortcuts. If given, the command will show up in Command Palette (Ctrl + K)
- closing a current tab now behaves like in Chrome: selects next tab (to the right). We used to select previously active tab, but that’s unpredictable and we prefer to align SumatraPDF behavior with other popular apps.
- swapped key bindings: i is now CmdTogglePageInfo, I is CmdInvertColors. Several people were confused by accidentally typing i to invert colors, is less likely to type it accidentally
- allow creating custom themes in advanced settings in Themes section. See docs.
- improve scrolling with middle click drag #4529
- make built-in keyboard shortcuts work on non-us keyboards (cyrillic , hebrew etc.)
- add CmdDuplicateInNewTab (Open Current Document In New Tab) command
