Pale Moon 34.3.0 (32-bit)

What's new in this version:

New features:
- Added powerPreference to canvas WebGL context for web compatibility
- Implemented support for the lch color space in CSS
- Added a base implementation for CSS stylesheet constructors
- Added a base implementation for CSS aspect-ratio sizing

- Added support for CSS shadow parts
- Added support for degenerate CSS values infinity, -infinity and NaN
- Implemented full LoongArch64 Baseline/Ion/WASM JIT compiler support
- Added AV1 decoding with Dav1d for more performant AV1 video playback on 64-bit builds. See implementation notes
- Note: AV1 is now enabled by default on Dav1d-supported configurations
- Added ES2024 Arraybuffer transfer APIs (resize, transfer, transferToFixedLength, detached, maxByteLength and resizable)
- Added support for growable/resizable SharedArrayBuffers and DataViews
- Added ES2024 grouping builtins (map .groupBy)
- Added ES2024 resolver builtins (.withResolvers())
- Added ES2024 String well-formed functions (.isWellFormed() and .toWellFormed())
- Added support for symbols as weak collection keys
- Added support for Atomics.waitAsync
- Added support for FinalizationRegistry (part of the WeakRef spec)

Changes/fixes:
- Switched our build system to Python 3. See implementation notes
- Linux: removed dbus-glib dependency
- Linux: Added EGL as a preferred OpenGL provider with GLX fallback; GLX remains the configured default as there are still some unresolved issues with EGL
- Improved JS performance by porting across various enhancements from Mozilla
- Fixed various application crashes
- Further improved compatibility with building for Loongson architectures
- Further improved hardware accelerated decoding of WMF videos
- Fixed ARM assembler issues in the Goanna back-end
- Improved parallel JS parsing tasks
- Improved CSS handling of calc() for web compatibility, allowing it in many more places (e.g. color() and z-index)
- For compatibility and performance reasons, we still strongly recommend that you use CSS variables to make calculations where possible
- Ported several smaller performance improvements from the Dactyloidae project
- Aligned CSS border width calculations with mainstream, for web compatibility. Please note that this may impact some themes that might rely on fractional border rounding (instead of truncation)
- Removed the CloudFlare workaround introduced in 34.2.0 as it should no longer be necessary with general image size handling improvements. The preference will no longer do anything
- White-listed driver vendors for VMWare, VirtualBox, VirtIO and Parallels to allow hardware accelleration as much as possible in VM environments
- Changed the implementation of WeakRef support to be always enabled in its full implementation
- Fixed some build issues on NetBSD
- Mac: Fixed a pertinent crash due to font handling on OS X 10.7 through 10.11
- Mac: Fixed build compatibility with 32-bit MacOS and Mac on PowerPC hardware
- Fixed a devtools crash on Big Endian machines
- Fixed an issue causing rendering artifacts on excessively large border-radius values (e.g. Tailwind CSS)

Security fixes:
- Fixed a stack corruption issue in nsLocaleService that could lead to crashes
- Implemented some ANGLE upstream fixes
- Updated NSS to 3.90.11 (UXP), picking up a number of upstream security fixes
- Another large security audit was performed of 190 security-sensitive reported bugs. Many security issues were addressed, including potential crash scenarios and code correctness issues.
- As a summary: 18 potential vulnerabilities were found applicable and fixed, another 18 issues had DiD code changes applied, and 4 were already mitigated by us before being reported. Of the reported security bugs, 150 were not applicable to our code (with a good portion once again pertaining to e10s/multi-process browser architectures).
