+---
+
+[Sep 0.12.0 was released November 12th,
+2025](https://github.com/nietras/Sep/releases/tag/v0.12.0) with a minor update
+to target `net10.0` and use the newly available
+[VectorXY.NarrowWithSaturation](https://learn.microsoft.com/da-dk/dotnet/api/system.numerics.vector.narrowwithsaturation?view=net-10.0&viewFallbackFrom=net-9.0). 
+
+There are no other functional changes in this release and .NET 10 does not
+improve upon Sep's already world class CSV performance. Cross-platform
+ `Vector256` parser is within performance of AVX-2 specific parser, as seen
+ below. So...

+
+That's all! 😁
+
+PS: There have been a few 0.11.x release with some minor feature additions.
+Check out [releases](https://github.com/nietras/Sep/releases) on GitHub for
+notes on this. Most of it is GitHub chore, though.
