Released this week was Rav1e 0.5 as the newest feature release for this Rust-written AV1 video encoder backed by Xiph.Org and self-proclaimed to be the world's "fastest and safest" AV1 encoder.

With Rav1e 0.4 having debuted back in January, there has been a lot of code churn since that point now part of Rav1e 0.5. There has been rebalancing of the speed levels and a variety of other enhancements over the course of the year.

Rav1e 0.5 sources along with Windows and macOS binaries are available for download from GitHub .

Our rav1e benchmarking test profile for the Phoronix Test Suite was already updated for rav1e 0.5 so from OpenBenchmarking.org are a lot of metrics for this new version on various processors.

Meanwhile on the open-source AV1 decode front, it's looking like dav1d 1.0 will be released soon. Dav1d developers are preparing their next release with a new threading model, AVX-512 code, and other improvements and looks like will christen it as v1.0.
