Hello,

The Apache Software Foundation recently changed its policy regarding the "Facebook BSD+patents" license that applies to zstd and many other FB open-source projects, and now considers it unsuitable for inclusion in ASF projects. There is a discussion of this in the context of RocksDB on LEGAL-303, which was resolved when RocksDB was relicensed as dual ALv2 and GPLv2.

Is the zstd community also open to relicensing with ALv2? This change would be helpful for Apache Hadoop (of which I'm a PMC member) since it would let us bundle zstd as part of our release artifacts. @omalley also expressed interest in this relicensing as an Apache ORC PMC member.

Thanks in advance!
