ArangoDB version 3.12.1 released

[vadim]

We are happy to announce the release of ArangoDB version 3.12.1!

This patch version is ready for production deployment and is a recommended upgrade for all 3.12 users.

Apart from some basic cleanup and code improvements related to found issues, the following notable things have been added to the 3.12.1 version of ArangoDB:

• Updated ArangoDB Starter to v0.19.3.
• Use __nss_configure_lookup to opt out of /etc/nsswitch.conf.
• Support indexHint AQL option for traversals.
• Update timezone database as of 25.06.2024.
• Rebuilt included rclone v1.65.2 with go1.22.4.
• Upgrade OpenSSL to 3.3.1 and used glibc build runtime to 2.39.0.
• Make the `beginAsync()` operation for transactions fully async also in the coordinator case, where it could previously block.
• Optimize performance of in-memory cache lookups under contention.
• Added ENTRIES function, that takes an object and produces a list of key-value pairs.
• Added new REST API endpoint HTTP DELETE `/_admin/log/level` to reset all log levels to their startup values.
• Added startup option `--cache.max-cache-value-size` to limit the maximum size of individual values stored in the in-memory cache.
• Added metric `arangodb_logger_messages_dropped_total` to count the number of log messages that were discarded by the logger if its log queue was full.
• Added option `skipFastLockRound` for transactions.
• Bundle ICU library version 64 with the build, so that persistent indexes and views relying on the old sort order can still be used without problems.
• Upgrade bundled version of nghttp2 library to version 1.61.0.
• Obsolete startup option `--server.max-number-detached-threads`.
