SeaLion-33.0.0

This is a new milestone release. It involves over 250 commits, of which the most important ones are highlighted here.

New features:

• Implemented a restricted version of the asynchronous clipboard API (navigator.clipboard). This API is restricted to writing only for obvious security considerations. It supports both plaintext and the standard DataTransfer methods. We did not implement the reinvented wheel concept of ClipboardItem objects.
• Implemented support for SHA-2 (SHA-256/SHA-512/etc.) signatures for OCSP stapled responses.
• Implemented PromiseRejectionEvent. Although this is rarely actually used, some common JS libraries (you know who you are!) use it as a feature level canary and start loading (broken!) Promise shims if it is not found, causing compatibility issues and broken websites due to the shims.

Fixes:

• Aligned microtasks and Promises scheduling with the current spec and expected behavior.
• We now no longer send click events to top levels of the document hierarchy when using non-primary buttons (use auxclick, instead, to capture these events).
• Greatly improved the performance of box shadows.
• Fixed several issues related to focus and content selection.
• Fixed issues with the use of focus-within caused by unexpected processing of DOM events.
• Fixed an issue with CSP not behaving as-expected when using importScripts(), and fixed a number of additional CSP-related issues.
• Greatly improved the performance of file/data uploads over HTTP/2 (most of the secure websites out there).
• Fixed an web compatibility issue with CORS preflights not sending the original request's referrer policy or referrer header.
• Fixed a crash due to clamping code introduced for SetInterval and SetTimeout timers.
• Fixed a spec compliance issue with StructureClone.
• Fixed crashes when dynamic imports are canceled (e.g. by navigation).

Other changes:

• Changed to now have its .files property be writable following a spec change and recommendation.
• We are now requiring and building against the C++17 language standard.
• Updated the in-tree ffvpx lib to 6.0.
• Updated the IntersectionObserver interface to now also accept documents for the observer root instead of only HTML elements.
• Cleaned up various bits of code surrounding GMP, memory allocation, system libraries, vestigial Android code, freetype2 and developer tools.
• Improved efficiency of handling D3D textures.
• Added initial and experimental Mac PowerPC and Big Endian support.
• Security issues addressed: CVE-2024-0746, CVE-2024-0741, CVE-2024-0743 DiD, CVE-2024-0750 DiD, and CVE-2024-0753.
• UXP Mozilla security patch summary: 3 fixed, 2 DiD, 12 not applicable.

If you notice incompatible extensions that use to work, download this archive again and reinstall those extensions.

SeaLion-32.5.1

Restricted protocol fallback for TLS. SeaLion (by default) allows TLS 1.3 to fall back to earlier protocol versions during the initial handshake.
UXP longer supports the data: protocol inside SVG's statements.
Enabled more validation/error checking for WebGL to prevent potential crashes.
Improved secure context checking for iframes.
Fixed the handling of relative paths in URLs starting with multiple forward slashes.
Security issues addressed: CVE-2023-6204, CVE-2023-6210, CVE-2023-6209 and CVE-2023-6205 DiD
UXP Mozilla security patch summary: 3 fixed, 1 DiD, 14 not applicable.

SeaLion-32.5.0

Changes/fixes from upstream UXP

• Added an initial implementation of the ReadableStreams API, improving web compatibility with sites that apparently use this API in utilitarian fashion.
• Added support for transparency in WebM videos for the edge case of using
• Added support for crypto.randomUUID to allow website scripting to generate random UUIDs (universally unique identifiers) through the WebCrypto interface.
• Implemented timer nesting and clamping for workers, preventing timer hangs on bas website code.
• Improved handling of drawing SVG images on canvases without explicit width or height attributes. We now follow the css-sizing-3 Intrinsic Sizes spec.
• Improved performance of our memory allocator.
• Updated libvpx to 1.6.1.
• Cleaned up and updated some media playback code.
• Removed the inclusion of GMP (Gecko Media Plugin) support as it was only in use for EME/DRM and WebRTC, neither of which is supported.
• Removed the last vestiges of EME/DRM code from UXP, since this will never be supported in any application building on it due to the media industry's draconic policies around FOSS.
• Removed simd.js, moving actually used SIMD handling to C++.
• Removed the use of libav in our source, replacing its supply of FFT with the equivalent from FFMpeg.
• Fixed potential type confusion in IonMonkey due to 3-byte opcodes.
• Fixed an issue with tooltips persisting even if the browser window would have lost focus.
• Fixed PerformanceObserver navigation and resource timing (default disabled for privacy); our implementation now fully passes conformance tests.
• Fixed an issue where top-level SVG images would not be correctly clipped by positioned elements, giving the impression of wrong z-ordering as the SVG would overlap other elements.
• Dev: Updated setInterval to fall back to 0 if no duration is supplied.
• Dev: Updated ResizeObserver to a recent spec change, now returning an array of results for borderBoxSize and contentBoxSize instead of an object.
• Dev: Updated Intl.NumberFormat and DefaultNumberOption() to follow spec updates. Most importantly for web compatibility, we now allow the "maximumFractionDigits" option in Intl.NumberFormat to be less than the default minimum fraction digits for the chosen locale, following the general consensus in TC39 around this issue.
• Increased leniency (removed upper limit) of GLSL versions as they tend to be fully backwards compatible.
• Fixed various crashes.
• Added a safeguard to the sec-gpc header (Global Privacy Control) so it cannot be inadvertently overwritten.
• Security fixes: addressed CVE-2023-5722, CVE-2023-5723, CVE-2023-5724, CVE-2023-5727 and several other issues without a CVE number assigned to them.
• UXP Mozilla security patch summary: 6 fixed, 2 DiD, 19 not applicable.
