Please help me unsubscribe from all couchdb mailing lists. I signed up many
years ago to this list when I wanted to try out couchdb. I have not been using
it since but I still receive countless emails.
I would appreciate any help I could get on this.
Thank you-- Tony

Dear community,

CouchDB 3.2.0 is a feature release and was originally published on 2021-10-12.
See the official release notes document for an exhaustive list of all changes:
http://docs.couchdb.org/en/stable/whatsnew/3.2.html#version-3.2.0
The community would like to thank all contributors for their part in making
this release, from the smallest bug report or patch to major contributions in
code, design, or marketing, we couldn’t have done it without you!
Release highlights:
- The couch_sever module is now sharded. Despite following a high-concurrency
process architecture generally, the couch_server module used in previous
versions is a single Erlang process that, on busy nodes, could become a
bottleneck. CouchDB 3.2.0 introduces a couch_server_N module per CPU core,
effectively removing the bottleneck.
- The replication scheduler manages which replications run at any one time. It
is important for setups where there are more total replications than are
configured to run concurrently. Previously, the replication scheduler would
iterate over all replications in a round-robin fashion and give them all equal
time to do their work. CouchDB 3.2.0 introduces a fair-share option that allows
you to use multiple _replicator databases each with a different relative
priority, so your important replications get more time to do their job vs. your
less important replications. See the _replicator DB docs for more details:
https://docs.couchdb.org/en/stable/replication/replicator.html#replicator
- Support for Erlang versions 23 and 24, dropped support for version 19.
- Support for SpiderMonkey versions 78 and 86.
- Addresses CVE-2021-2838295
- Reduced occurrence of the “No DB shards can be opened”
- Support specifying password requirements via regex
- Logs no longer include credentials in almost all cases
- More fine-grained CSP configuration
- Easier development setups via .devcontainer for the 3.x series.
- Makes auto-compaction less aggressive, saves CPU and I/O on busy clusters.
- Includes weatherreport module for advanced diagnostics:
-

- Includes a dedicated prometheus endpoint for stats and metrics:
-
https://docs.couchdb.org/en/latest/api/server/common.html#api-server-prometheus
- All JS tests have been migrated Elixir and the JS test suite has been
retired. 🖖
