### Added

- Expose more API in libglycin that was needed by gdk-pixbuf glycin loaders to
  work correctly.

### Fixed

- Allow `exit_group` syscall, needed by some systems to load SVGs.
- Allow recv syscall since it is needed on PowerPC64 LE.
- Apply rotation to the dimension in `Image` as well. They were correct in
  `Frame`s already.
- Bump gufo-jpeg to fix editing some JPEGs saved with progressive mode.
- Fix glycin-thumbnailer not working inside the thumbnailer sandbox due to an
  issue introduced in zbus 5.7. Pin to zbus 5.6 for now. See
  <https://github.com/dbus2/zbus/pull/1472>
- Regular unnecessary recompiles of components.
- glycin/sandbox: Allow `{get,set}priority` syscalls, since they are used by
  libheif on Gentoo.

### Changed

- Don't use the image-rs feature in jpegxl-rs to convert texture date to avoid a
  copy of the data. This speeds up loading.
- glycin: Parallelize ICC profile transformations.
- jxl: Use a parallel runner for decoding, reducing image loading times.

## 2.0.beta.2 (2025-08-01)

- libglycin-gtk4: gly_gtk_frame_get_texture now sets the GdkColorState if a CICP
  value is present.

### Fixed

- glycin: Pool according to sandbox mechanism. Previously, a wrong mechanism
  could be used, if different mechanisms inside the same process were requested.

## 2.0.alpha.7 (2025-07-07)

This release contains the following new component versions:

- glycin-common 1.0.0-alpha.7

- Instead of using the STDIN of the loader/editor for the D-Bus connection, use
  a new FD, specified via the command line.
- Moved some type definition to a new glycin-commons crate for better API
  stability.
- Rename various fields in the internal API for clarity.
- The editing API is now split into two steps: First the image is loaded. Then,
  onto the loaded image, differente editing operations can be applied. This can
  speed-up the preview of editing operations, since the image doesn't need to be
  loaded each time.
- glycin: Wrap the internal APIs into glycin specific types to guarantee API
  stability.
- jxl: Require libjxl 0.11

## 2.0.alpha.6 (2025-07-03)

  EXR, QOI. Without these, the creator API is not working.

### Changed

- glycin: The sandbox selector now also disables the sandbox for app IDs that
  end in `Devel`, not just `.Devel`.

## 2.0.alpha.5 (2025-06-27)

## 2.0.alpha.2 (2025-06-13)

This release contains the following new component versions:

- glycin-tools 2.0.0-alpha.2

- glycin-raw 2.0.0-alpha.2
- glycin-svg 2.0.0-alpha.2
- glycin-thumbnailer 2.0.0-alpha.2

### Added

- Added specific error for when requesting the next frame and there are no more
  frames left.
- Pooled loaders and editors. Pooled loaders will re-use existing loader
  processes, without having to go through the costly process of spawning a new
  loader. Using pooled loaders will drastically increase the speed for loading a
  lot of small images, like, for example, thumbnails. Loader and editor pools
  are now used by default. Loader processes are spawned on demand. The pools are
  not shared between processes or apps.
- Return `key_value` metadata from PNG's tEXt and zTXt chunks.
- glycin: Create loaders from bytes in memory or a `GInputStream` instead of a
  `GFile`.
- glycin: Support setting accepted memory formats. If a texture isn't using a
  specifieds memory format, it will be transformed into one specified as
  supported.

### Fixed

- Previously, loaders could exit early if the thread in which they were created
  was terminated.

### Changed

- Exposing the base directory is no longer enabled by default. For loading SVGs
  that include external images, `loader.use_expose_basedir(true)` has to be
  used.
- Use a new loader/editor D-Bus API version 2+ and simultanously bump libglycin
  to 2.0 and glycin (Rust API) to 3.0. This was required for supporting pooled
  loaders.

## 1.2.4 (2025-09-11)

This release contains the following new component versions:

- glycin 2.1.4
- libglycin 1.0.4
- glycin-svg 1.2.4

### Fixed

- glycin/sandbox: Allow `recv` syscall. Needed on powerpc.
- jpeg: Bump gufo-jpeg to fix editing some JPEG with progressive mode.
- svg: Correctly define data from rsvg as premultiplied.

## 1.2.3 (2025-08-01)

This release contains the following new component versions:

### Fixed

- Fix editing for PNGs and JPEGs that are already rotated via an orientation tag
  in the Exif data.
- Remove rotation via legacy Exif rotation entries when editing PNG images to
  not make them aditionally rotated after editing. This is a fix just for legacy
  Exif entries via tEXt and zTEx chunks with keyword "Raw profile type exif".
- Revert to using sRGB instead of Rec2020 to pass images with ICC profile to
  GTK. This fixes some color deviations when displaying the images.
- glycin: Allow additional syscalls needed for armv7 and on Alpine Linux in
  sandbox.

## 1.2.0 (2025-03-14)

This release contains the following new component versions:

  color space to GTK, supporting a far wider color gamut than the sRGB format
  before

## 1.1.6 (2025-02-27)

### Fixed

- apng: Also support image/apng mime-type in loader.

## 1.1.5 (2025-02-24)

### Fixed

- apng: Support image/apng mime-type to support animated PNGs again. This mime-
  type is now detected due to upstream changes at xdg/shared-mime-info.

## 1.1.4 (2024-01-03)

This release contains the following new component versions:

- libglycin 1.0.0
- libglycin-gtk4 1.0.0

### Fixed

- image-rs: Support `image/qoi` mime-type for QOI in addition to `image/x-qoi`.
- libglycin: Include stdint.h.
- libglycin: Remove dependency on gtk in header and move it to libglycin-gtk4.

## 1.1.2 (2024-11-22)

### Added

- Output loader output as debug messages. The loader output is captured and
  added to errors. But it's not accessible if the loader doesn't return. In that
  case, this feature is useful.

### Fixed

- Fix jpegxl-rs version to 0.10.3. Version 0.10.4 does not build on arm64 and
  builds libjxl instead of using the system library.
- Fix memory format mapping for RGBA 32bit float image from image-rs. This fixes
  rendering for a lot of OpenEXR images.
- glycin-heif: Disable bindgen for libheif-rs since it won't build with libheif
  1.19 or newer otherwise.

## 1.1.1 (2024-09-16)

### Fixed

- Glycin failed to detect the SVGZ format since the files were just detected as
  gzip files via the magic bytes.

## 1.1.0 (2024-09-13)

### Fixed

- tests: Update to test image which uses an explicit font name in SVG, not
  depending on the correct default font setting on the system for the test to
  pass.

### Changed

- glycin-utils: Don't use regex feature of env-logger to save almost 1 MB binary
  size in each loader

## 1.1.beta (2024-08-02)

### Added

- Add tests for animations
- Automatically detect if glycin is used inside a Flatpak development
  environment and disable sandbox in that case. Otherwise, flatpak-spawn
  wouldn't use the loaders from the right Flatpak or might not find a installed
  Flatpak at all.
- Capture the stderr and stdout from loaders and editors and included it in the
  new ErrorCtx type that the API now returns

### Fixed

- Also include free swap as free memory in the calculation of how much memory a
  loader can use
- If the fontconfig cache was not up-to-date, rendering SVGs with text would
  fail. There is now a loader config option to enable passing a writable
  fontconfig cache dir into the loader sandbox. This fixes the issue. The cache
  is per loader binary.
- Sealing memfds sometimes fails. Is is solved via retrying the seal until it
  works. In the past this was limited to very short time of retries. The
  interval is now much longer and properly async.
- There was an error in the hardcoded limit for the texture size. The limit is
  now fixed and 8GB as intended.

## 1.1.alpha (2024-06-28)

### Added

- A specific error if no loaders are configured instead of giving an unknown
  format error
- Bindings for C and other languages via GObject Introspection under the name
  libglycin and libglycin-gtk4
- Loaders are now accompanied by editors that can return an image with image
  operations applied
- Option to use tokio throughout instead of async-io
- glycin: List of mime types `glycin::DEFAULT_MIME_TYPES` that the default
  loaders support
- glycin: New loader option to apply transformations like rotate/mirror from
  metadata by default
- loaders: Use specific OutOfMemory error type

- glycin: Don't allow access to / in bwrap sandbox
- glycin: Limit memory using when using bwrap sandbox
- glycin: Don't block on applying ICC profiles
