Baixar Thorium 3.1.0 per a Windows

Summary
Version 3.1.0 was released on 17 February 2025.

This release includes the following (notable) new features, improvements and bug fixes:
- Localization: updated translations, Weblate now recommended instead of GitLocalize
- Feature: annotations, import + export (various "selector" formats powered by Apache Annotator, tested with DOM Ranges spanning across XHTML, SVG, MathML, foreignObject, etc.) and updated graphical user interface (list filtering, etc.)
- Feature: TTS readaloud and EPUB3 Media Overlays, option to disable continuous playback (checkbox in playback settings panel)
- Feature: visual navigation indicators in HTML publication documents (temporary outline) can now be disabled
- Feature: additional information labels in the "settings" GUI to describe actions and choices
- Feature: URL query params 'lang' and 'version' to online documentation
- Feature: TTS readium-speech integration, organised and opinionated voice selector
- Feature: TTS and EPUB3 Media Overlays, popup foonotes are disabled so that they can be played inline as intended by content creators
- Feature: "preferred" settings for reader configuration, save/load/reset
- Feature: PDF.js latest library version
- Feature: latest Electron v34 (i.e. more recent Chromium web browser engine and NodeJS runtime)
- Fix: XML parsing in DAISY 2.02 NCC.html was choking on doctype with empty declaration [], also SMIL parser fix for skippables (system-required sidebar-on and note-on), and merge of contiguous SMIL SEQ/AUDIO inside PAR
- Fix: XML parser UTF8 BOM Byte Order Mark removal
- Fix: TTS readaloud SVG deep utterances (no aria-label / title), escapability
- Fix: TTS Japanese Ruby skipped (ignored) when visually hidden, played instead of base / non-Ruby when visually displayed (does not use skippability semantics of TTS / EPUB3 Media Overlays)
- Fix: accessibility labels in some user interface controls, improved GUI structure and semantics
- Fix: accessibility metadata, preliminary update (more to come in a future release) to match the latest presentation guide, support for printPageNumbers vs. pageBreakMarkers vs. pageNavigation
- Fix: download panel was reporting incorrect status (mismatched unique identification), URL was conflated with label, added support for unknown content-length (indeterminate progress bar), handling of content-disposition UTF8 percent-escaped filename, consume www-authenticate response error description, HTTP content-type was taking the precedence over content-disposition header
- Fix: LCP provider certificate expiration error messaging
- Fix: bookmarks were incorrectly synchronised when several reader windows were open
- Fix: OPDS and other publication download authentication flow across domains, also fixed OAuth 2.0 Implicit Grant flow (client ID etc.)
- Fix: added missing keyboard shortcuts in library view for first/last previous/next
- Fix: keyboard focus "inversion of control" (eliminated focus stealing), Thorium GUI now pushes requests to navigator / HTML document renderer, removed body-injected underscore / jump link, automatic vs. manual keyboard redirection from modal vs. docked navigation panels, added keyboard shortcut to force-focus deep into the webview (just in case the default method fails, depends on Chromium behaviour of out-of-process iframe inside shadow DOM / custom element)
- Fix: command line lifecycle / action flow
- Fix: various GUI issues
- Fix(dev): updated Continuous Integration / GitHub Actions scripts, added dependency analyser script, introduced support for Flox/Nix, improved Linux Docker builder, adde NPM scripts lifecycle checks (pre/post/install security)
