Updates harfrust from 0.12.0 to 0.13.3

Release notes

Sourced from harfrust's releases.

0.13.3

This release matches HarfBuzz v14.3.1, and has an MSRV (minimum supported Rust version) of 1.85.

• Add support for shaping legacy AAT mort tables, including language-specific morph features (#451, #453).
• Handle tuple kerning in AAT kerx tables (#452).
• Fix a debug assertion for legacy kern state tables that declare more than 256 classes (#455).
• Synthesize Arabic fallback GSUB lookups, including legacy Windows-1256 glyph layouts and no_std builds (#454, #456).
• Update read-fonts to 0.43.3.

0.13.2

This release matches HarfBuzz v14.3.1, and has an MSRV (minimum supported Rust version) of 1.85.

• Speed up contextual and chained-context lookup matching by probing raw rule offsets and reusing parsed coverage tables (#437).
• Skip the redundant per-subtable digest test for single-subtable lookups (#438).
• Set up glyph-set acceleration before applying legacy kern tables (#439).
• Precompute and pack AAT state-machine safe-to-break probes in the face cache (#445).
• Cache reusable shaping table metadata and avoid moving shaper and buffer temporaries on every shape (#446, #447).

0.13.1

This release matches HarfBuzz v14.3.1, and has an MSRV (minimum supported Rust version) of 1.85.

• Saturate shaping and positioning math across GPOS, kerx, trak, fallback, shaping, metrics, and font scaling paths to avoid overflow and better match HarfBuzz behavior (#420).
• Cache GDEF mark filtering sets in bitmaps (#421).
• Lock icu_properties to 2.2.0 (#422).
• Optimize hot loops in contextual and layout matching by probing rules before parsing, hoisting invariants, moving recursion state instead of cloning, and replacing per-element copies with block copies (#423, #424, #425).
• Optimize buffer internals by copying small counts inline and charging move_to operations against max_ops (#426, #429).
• Improve AAT shaping performance by walking morx subtables through packed descriptors, resolving subtable kinds from cached parts, and adding a state-machine fast path (#428, #430, #431).
• Skip the post-morx digest update when GPOS is not present (#433).
• Add a batched nominal-glyph callback to FontFuncs (#434).
• Update read-fonts to 0.43.2 (#432, #435).

0.13.0

This release matches HarfBuzz v14.3.1, and has an MSRV (minimum supported Rust version) of 1.85.

Full Changelog: pdeljanov/Symphonia@v0.6.0...v0.6.1

v0.6.0

Welcome to Symphonia 0.6! 👋

Symphonia 0.6 is the culmination of two years of effort to rework Symphonia from an audio-focused multimedia framework to one that can be extended to support video and subtitles as well. While Symphonia does not yet support video and subtitle decoders, the groundwork laid in this release should allow easier prototyping of those features, and to more seamlessly introduce them in the future. As such there are significant breaking changes present in this release for existing users.

See the migration guide for detailed information on how to move to Symphonia 0.6.0.

New Features

• Format readers and decoders may now be registered with a preference tier/priority
• Format and metadata readers now provide methods to get information about themselves
• Format readers can now expose attachments (e.g., attached fonts)
• Decoders can now decode from non-owning packets, eliminating a copy if using a non-Symphonia demuxer
• ID3v1, APEv1, and APEv2 metadata formats are now supported
• Added support for chapters for Matroska, ID3v2, and Vorbis Comments
• Added support for Matroska metadata
• Image format and parameter detection for visuals
• Metadata tags that have an official or defacto meaning are parsed where possible (e.g., a track number tag is parsed into an u64)
• MediaSourceStream, and all downstream consumers (e.g., FormatReader), are now generic across the lifetime
• SIMD optimizations are enabled by default

Updates egui from 0.36.2 to 0.37.0

Release notes

Sourced from egui's releases.

0.37.0 - Colored emojis! 🚀

egui is an easy-to-use immediate mode GUI for Rust that runs on both web and native.

Try it now: https://www.egui.rs/

egui development is sponsored by Rerun, a startup building an SDK for visualizing streams of multimodal data.

Highlights ✨

Emoji and glyph support

egui can now render any glyph that is supported on your system, including colored emojis and non-Latin scripts.

To enable this, the integration has to use one of two APIs:

• Context::add_glyph_rasterizer(GlyphRasterizer): a GlyphRasterizer renders a single glyph. eframe uses this on web to render individual glyphs to an off-screen canvas #8490, #8545.
• Context::add_font_provider(Arc<dyn FontProvider>): lets egui find and load whole fonts at runtime. Native eframe uses this through the new egui_system_font_provider crate, which lists system fonts with fontique #8512.

Completion popup

We've added a new CompletionPopup widget that adds autocomplete to a TextEdit. You can use it e.g. to add emoji selection like in discord:

Screen.Recording.2026-10-15.at.16.05.41.mov

Experimental theme customizations

This release adds a theme plugin system #8153 by @​AdrienZianne. Enable the new experimental feature flag, and there will be a new StyleProvider trait, which can be used to customize visuals for a widget based on the provided classes.

/// Implement the trait for each Widget you'd like to customize
impl StyleProvider<ButtonStyle> for MyTheme {
  fn style(&mut self, args: &StyleArgs<'_>) -> ButtonStyle {
    // You could construct ButtonStyle from scratch, or extend eguis built in style:
    let mut style: ButtonStyle = DefaultStyle.style(args);
    if args.has_class("primary") {
      style.atom_layout.frame.fill = hex_color!("#FF0000");
    }
    style
  }
}
/// Register all your custom style providers
fn init(ctx: &Context) {
ctx.add_widget_theme::<ButtonStyle>(MyTheme);

Record videos of integration tests

Reading an integration test to understand what its doing can be challenging, so we've added a egui_kittest/video feature that records a mp4 video from it, using ffmpeg! Enable it and pass EGUI_KITTEST_RECORD=1 or EGUI_KITTEST_RECORD=open, and a video of the test will be recorded. This is an example from one of our more complex rerun integration tests:

impl StyleProvider<ButtonStyle> for MyTheme {
  fn style(&mut self, args: &StyleArgs<'_>) -> ButtonStyle {
    // You could construct ButtonStyle from scratch, or extend eguis built in style:
    let mut style: ButtonStyle = DefaultStyle.style(args);
    if args.has_class("primary") {
      style.atom_layout.frame.fill = hex_color!("#FF0000");
    }
    style
  }
}
/// Register all your custom style providers
fn init(ctx: &Context) {
ctx.add_widget_theme::<ButtonStyle>(MyTheme);
ctx.add_widget_theme::<CheckboxStyle>(MyTheme);
// ...
}

Record videos of integration tests

Reading an integration test to understand what its doing can be challenging, so we've added a egui_kittest/video feature that records a mp4 video from it, using ffmpeg! Enable it and pass EGUI_KITTEST_RECORD=1 or EGUI_KITTEST_RECORD=open, and a video of the test will be recorded. This is an example from one of our more complex rerun integration tests:

Updates cpal from 0.16.0 to 0.18.2

Release notes

Sourced from cpal's releases.

cpal 0.18.2

Added

• AAudio: Xruns are now reported as ErrorKind::Xrun.
• CoreAudio: Xruns are now reported as ErrorKind::Xrun.
• PipeWire: Xruns are now reported as ErrorKind::Xrun.
• WASAPI: Capture xruns are now reported as ErrorKind::Xrun.

Changed

• BSD: Clarify that realtime-dbus has no effect there.
• CoreAudio: Bump objc2-core-foundation dependency lower bound to 0.3.1.
• iOS: Timestamps now include hardware latency and update when the audio route changes.
• JACK: Timestamps now include port latency.
• Linux: Clarify that realtime alone is a no-op without realtime-dbus.
• PipeWire: Devices with multiple ports now get distinct, localized, per-port names.
• WASAPI: The windows and windows-core dependencies are now both pinned to 0.62.

Fixed

• Timestamps now stay monotonic across device and graph changes.
• ALSA: A nonzero but sub-millisecond stream timeout is no longer treated as a non-blocking poll.
• ALSA: Fix compilation on FreeBSD, DragonFly, and NetBSD.
• ASIO: Fix duplex streams silently dropping audio when built from separate Device handles.
• AudioWorklet: Fix Stream operations to work when called from any thread.
• AudioWorklet: Fix stale audio output when a data callback wrote a partial buffer.
• CoreAudio: Fix stale audio output when a data callback wrote a partial buffer.
• CoreAudio: Default-output streams now report xrun status.
• iOS: Streams now resume automatically when an audio session interruption ends.
• JACK: Streams with more channels than physical system ports no longer fail to build.
• JACK: Channel enumeration is no longer capped at the physical system port count.
• JACK: Device::id no longer embeds the process ID, so DeviceId is now stable across application restarts.
• PipeWire: Fix streams starting audio before play() is called.
• PipeWire: Fix real-time promotion blocking the audio callback thread on Linux.
• PipeWire: Fix rtkit burst limit errors from repeated real-time promotion on quantum jitter.
• PipeWire: Fix 24-bit sample format mapping.
• PipeWire: Nodes with an /Internal media class are now enumerated as devices.
• PipeWire: Streams for a specific device no longer auto-reroute if it disappears.
• PipeWire: Build on 32-bit targets without native 64-bit atomics.
• PulseAudio: NoData errors are no longer misreported as buffer xruns.
• PulseAudio: Build on 32-bit targets without native 64-bit atomics.
• visionOS: The CoreAudio backend now builds.
• WASAPI: Stream::drop, play, and pause no longer panic when the device is lost.
• WASAPI: Output streams no longer reject formats that the built-in resampler can convert.
• WASAPI: Fix 24-bit samples not being packed into the upper bits of their sample container.
• WASAPI: Reported buffer sizes are no longer off by one frame.
• WASAPI: Default device changes no longer report DeviceChanged, which wrongly implied the stream had rerouted automatically.
• WebAudio: Fix stale audio output when a data callback wrote a partial buffer.
• WebAudio: Fix unsound Send + Sync on Stream when compiled with +atomics.
• WebAudio: Fix Host::is_available() always returning true, even in non-window contexts.

Looks like these dependencies are updatable in another way, so this is no longer needed.
