### Added

- Add "test_disable_sandbox" option to disable use of sandbox while running
  tests.
- Cross compilation should now work out of the box and not require any patches.
- Setting `GLYCIN_DISABLE_SANDBOX=i-know-the-risks` will disable the sandbox if
  `SandboxSelector::Auto` is used.
- Support conversion of pixel densities between different units.

### Fixed

- Don't report JPEG 2000 images as format name ICO.
- libglycin: Build errors on Windows MSVC and macOS. Builds unter Windows GNU
  are still not completely working.

### Changed

- The pixel density is now provided as it's own object. This is a breaking
  change towards the previous alpha version.
- sandbox: Use seccomp blocklist instead of allowlist.      The allowlist has
  repeatedly caused issues because it's not clear when new syscalls need to be
  added. Since seccomp is a second line of defence on top of namespaces anyway,
  this should be totally fine. Don't block socket calls for now since it's a bit
  complicated and they were allowed before.  This also fixes issues where
  multiarch setups would run into a second arch not being properly handled by
  seccomp. #269
