OpenZFS Developer Summit
The goal of the event is to foster cross-community discussions of OpenZFS work and to make progress on some of the projects we have proposed. This 2-day event consists of a day of presentation and a 1-day hackathon.

Congratulations to our 4 "best in show" winners, who received Intel Compute Sticks, donated by Intel.
- zpool checkpoint (Dan Kimmel, Serapheim Dimitropoulos). Allows reverting the entire pool to a previous state.
- preferred ashift (George Wilson). Allows dynamically switching to 4K sector aligned allocations
- zstd compression algo (Saso Kiselkov). Better compression ratio & faster than zlib/gzip.
- testing encryption with Illumos debug kernel (Tom Caputi & Dan McDonald). Using ::findleaks and kmem_flags=0xf to find bugs in encryption implementation
