New Features

  • Updated Firefox to 158.0
  • Added a --space <id|name> option to the command line interface.
  • Library will now show a 'Open in Folder' option and download speed when hovering over the toolbar icon.
  • Zen now creates more accessible PDFs when saving a page as PDF, and when printing on Linux and macOS. This also fixes a variety of PDF rendering issues, such as missing math symbols.

Fixes

  • Fixed various animation, urlbar and UI performance issues.
  • Fixed Library media tab requesting onedrive to download all files from cloud. (#15888)
  • Fixed unwanted label next to the search icon in urlbar. (#14856)
  • Fixed Avahi access so CUPS printers are listed in flatpak sandbox. (#9651)
  • Fixed various memory leak issues. (#15954)
  • Fixed a crash that could occur while Zen loaded website icons (favicons).
  • Fixed menus such as List all tabs, Settings, etc being hard to read with a Windows High Contrast theme. Menu background and text colors now follow the Background and Text colors chosen for a custom contrast theme in Windows Settings.
  • Other bug fixes and improvements.

Changes

  • Space routing regex will now match URLs as case-insensitive.
  • Library's widget hover list will now only display recently downloaded files.
  • Zen no longer rounds scroll positions to whole screen pixels. Scrolling is now smoother and more precise, especially on high-resolution displays or when a page is zoomed.
