ds5678 03713d8d57 Update version to 2.6.2 in Directory.Build.props
Bump the VersionPrefix property from 2.6.1 to 2.6.2 to prepare for the next release.
2026-06-02 14:44:26 -07:00
ds5678 3cf2170242 Ensure that blocks with all bits set do not throw 2026-06-02 14:32:22 -07:00
ds5678 0a8bae09cf Refactor: use Span.Fill for block color assignment
Replaced manual for loop with Span.Fill to efficiently assign a color value to the output span in ASTC block decoding. This improves code readability and performance.

ds5678 801edea4cf Bump version prefix to 2.6.1
Updated Directory.Build.props to increment the VersionPrefix from 2.6.0 to 2.6.1. This prepares the project for the next release.

ds5678 3cb859c6ac Update NuGet package versions across project files
Updated several NuGet dependencies to their latest versions:
- AssetRipper.Text.SourceGeneration to 1.2.3
- Microsoft.SourceLink.GitHub to 10.0.103
- Microsoft.NET.Test.Sdk to 18.3.0
- NUnit to 4.5.0
- coverlet.collector to 8.0.0
These updates provide bug fixes, new features, and improved compatibility.

ds5678 0738ba4b50 Multi-target .NET 8 and 10
I currently don't use any API above .NET 8, so multi-targeting 8 and 10 is fine for now. However, if I later need a higher .NET version, I won't hesitate to drop support.

ds5678 09067cecbb Replace Unsafe.As with Unsafe.BitCast where appropriate 2026-02-26 17:39:51 -08:00
