- native support for UUIDv7
- substantial speedups for bulk operations, purge operations and any btree operations by introducing a cache
- support for Debian Trixie
- Erlang 26 as minimum version
- Allow safe downgrading of CouchDB versions

Which makes it a pretty cool release :)

Most surprising though is that the scanner found more differences in SpiderMonkey versions (1.8.5, 76, 81, 115, 128) than SpiderMonkey vs QuickJS. We’ve copiously documented the differences: docs.couchdb.org/en/stable/be...

That said, the 3.5.1 highlights aside from bugfixes are:

Since version 3.4 which introduced QuickJS, CouchDB ships with a background scanner module that will urn your SpiderMonkey JS in QuickJS and reports any incompatibilities. That you you can know ahead of time if it is safe to migrate:

- we even had to ship 3.5.1 with just QuickJS because RHEL/Alma 10 doesn’t do SM anymore at all.

QuickJS is smaller, faster, lower memory footprint and we made it safe to migrate.

Heads up for the next feature release 3.6.0: QuickJS will take over from SpiderMonkey as the default JavaScript engine.

As a database, we make heavy use of automated testing and any and all contributions in this area are very welcome. Thank you DigitalOcean! www.digitalocean.com
