These release notes are summaries of the most important changes for public releases.
This is a new milestone release.
Primary focus for this milestone is web compatibility, in particular Regular Expression extensions, standards compliance issues and further JPEG-XL support.
Special thanks to Martok, Job Bautista and FranklinDM without whom this milestone would not have been possible.
Most important changes:
- Implemented Regular Expression named capture groups.
- Implemented Regular Expression unicode property escapes.
- Re-implemented Regular Expression lookaround/lookbehind (without crashing this time ;) ).
- Implemented progressive decoding for JPEG-XL.
- Implemented animation for JPEG-XL.
- Renamed CSS
offset-* properties to
inset-* to align with the latest spec and the web.
- Fixed CSS inheritance and padding issues in some cases.
- Aligned parsing of incorrectly duplicated HSTS headers with expected behavior (discard all but the first one).
- Implemented a method to avoid memory exhaustion in case of (very) large resolution animated images.
- Updated the JPEG-XL and Highway libraries to a recent, stable version.
- Cleaned up some unused CSS prefixing code.
- Improved the ability to link on *nix operating systems with other linkers than gcc's default.
- Stability improvements (potential crash fixes).
- Security issues addressed: CVE-2023-23598, CVE-2023-23599 and several others that do not have a CVE number.
- UXP Mozilla security patch summary: 4 fixed, 2 DiD, 19 not applicable.
This is a major development, bugfix and security release.
- Added support for the JPEG-XL image format.
- Implemented regular expressions lookaround/lookbehind.
- Aligned CORS header parsing with the updated spec. See implementation notes.
- We no longer fire keypress events for non-printable keys. See implementation notes.
- Added support for MacOS 13 "Ventura" in the platform, primarily benefitting White Star.
- Fixed potentially problematic thread locking code on *nix platforms.
- Fixed some small issues in the display and operation of the Web Developer tools.
- Removed unused but performance-impacting panning and tab animation measuring code. (telemetry leftovers)
- Improved code for SunOS builds.
- Updated Internationalization data for time zones.
- Fixed a buffer overflow for Mac builds.
- Fixed an issue with plugins not receiving keypress events properly.
- Added some extra sanity checks to our zip/jar/xpi reader to avoid issues with corrupt archives.
- Aligned cookie checks with RFC 6265 bis. See implementation notes.
- Removed obsolete code in Windows widgets that could cause potential issues with long paths and file names on supported versions.
- Fixed several crashes.
- Security issues addressed: CVE-2022-45411, CVE-2022-46876, CVE-2022-46874 and several others that do not have a CVE number
- UXP Mozilla security patch summary: 6 fixed, 1 DiD, 1 deferred, 45 not applicable.
- RFC 6265 has been worked on with draft changes describing how cookies are actually being handled in the real world, in the bis versions of the RFC. While these changes have not yet been finalized, browsers in general do adhere to the latest available bis version of this RFC. Specifically, the long-standing exceptions for cookie names and values have been formalized, e.g. having quoted values. Our behavior has changed in that we now once again accept Tab characters (0x09) which is the one excluded control character from the range that is otherwise forbidden. We also no longer apply these checks exclusively to those in http headers, and any way of setting cookies must now adhere to the valid range. Cookies that fail these range checks for valid characters will be ignored.
- CORS support has been updated to the current spec. Most importantly, Basilisk now accepts wildcard entries ("*") for the CORS statements Access-Control-Expose-Headers, Access-Control-Allow-Headers and Access-Control-Allow-Method. Note that wildcards are ignored (according to the spec) when credentials are passed.
- Basilisk will no longer fire the keypress events in content when the key pressed is a non-printable key. This is in response to issues where webmasters would use rudimentary and naïve input-restricting scripts in onkeypress handlers that would not take into account editing keys or navigation keys, causing issues for users trying to enter data into forms (and e.g. finding they could no longer use backspace, cursor keys or tab). This aligns our behavior with other browsers for web compatibility, although it should be considered a website error expecting not all keypresses to be intercepted in keypress events.
This is a security and compatibility update.
Note: The Basilisk branding has been removed from the Basilisk repository.
- Added detection suport for the newly-released MacOS 13 (Ventura).
- Fixed a potential heap Use-After-Free risk in Expat. (CVE-2022-40674) DiD
- Fixed potentially undefined behavior in our thread locking code. DiD
- Fixed a potentially exploitable crash in the refresh driver.
- Fixed potentially undefined behavior when base-64 decoding. DiD
- Implemented a texture size cap for WebGL to prevent potential issues with some graphics drivers. DiD
- Updated site-specific overrides to address issues with ZoHo.
- UXP Mozilla security patch summary: 1 fixed, 2 DiD, 6 not applicable.
This is a major development, bugfix and security release.
Note: The default serch engines have changed. Please verify that your configuration still uses your preferred search engine.
- Implemented the use of EventSource in workers.
- Enabled the sending of the Origin: header by default on same-origin requests.
- Changed how Basilisk is built. We have made build system changes to reduce build times and pressure on the linker on all platforms. Note that Basilisk is not yet built with Visual Studio 2022. This change will be done in the next release.

This is a major update.
Very Important: This is the first public release from the Basilisk Development team. As such, the vendor name in the application has changed. This means the profile directory has changed. See here for more info.
You will have to perform a manual update if you are currently running Basilisk 2022.01.27 as it was compiled without an updater.
Note: Many things have changed since 2022.01.27 and 2022.08.06. We've tried to note all changes here but it is very likely something was missed.

- Fixed an issue with iframe sandboxing not being properly applied. (CVE-2022-22759)
- Fixed a potential leak of bookmarks from the exported bookmarks file if it included a malicious bookmarklet.
- Fixed an issue with drag-and-drop. (CVE-2022-22756)

- Implemented Global Privacy Control, taking the place of the unenforceable "DNT" (Do Not Track) signal. Through GPC, you indicate to websites that you do not want them to share or sell your data.
- Implemented "optional chaining" (thanks, FranklinDM!).
- Implemented setBaseAndExtent for text selections.
- Implemented queueMicroTask() "pseudo-promise" callbacks.
- Implemented accepting unit-less values for rootMargin in Intersection observers for web compatibility, making it act more like CSS margin as one would expect.

- Improved display of cursive scripts (on Windows). Good-bye Comic Sans!
- Updated various in-tree libraries.
- Added support for extended VPx codec strings in media delivery via MSE (RFC-6381).
- Fixed a long-time regression where the browser would no longer honor old-style body and iframe body margins when indicated in the HTML tags directly instead of CSS. This improves compatibility with particularly old and/or archived websites.

- Restored Mac OS X code and buildability in the platform.
- Removed the non-standard ArchiveReader DOM API that was only ever a prototype implementation.
- Removed most of the last vestiges of the invasive Mozilla Telemetry code from the platform. This potentially improves performance on some systems.
- Removed leftover Electrolysis controls that could sometimes trick parts of the browser into starting in a (very broken) multi-process mode due to some plumbing for it still being present, if users would try to force the issue with preferences. Obviously, this was a footgun for power users.
- Removed more Android/Fennec code (on-going effort to clean up our code).
