2.9.0

What's Changed

Note

Version 2.9.0 increases the minimum supported targets.

• ➕ net8.0 and netstandard2.1 were added
• ❌ net45 was bumped to net461 (via netstandard2.0)
• ❌ netstandard1.3 is no longer supported (NETSDK1215)
• ❌ net3.5 is no longer supported

These changes allow the library to utilise APIs with better performance. The removed frameworks are all very old and out of support, so we expect impact to be minimal. If you require these old targets, stick on an old version of this library.
