Sep 0.12.0 was released November 12th, 2025 with a minor update to target net10.0 and use the newly available VectorXY.NarrowWithSaturation.

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 on GitHub for notes on this. Most of it is GitHub chore, though.
