ArangoDB version 3.11.2 released

[vadim]

We are happy to announce the release of ArangoDB version 3.11.2!

This patch version is ready for production deployment and is a recommended upgrade for all 3.11 users.

Apart from some basic cleanup and code improvements related to found issues, the following notable things have been added to the 3.11.2 version of ArangoDB:

• Updated ArangoDB Starter to 0.16.0.
• Added startup option `--database.max-databases` to limit the maximum number of databases that can exist in parallel on a deployment.
• Arangodump retries dump requests in more cases: read, write and connection errors.
• Added transparent LZ4 compression for values in the in-memory edge cache if their size exceeds a configurable threshold.
• Added startup option `--replication.active-failover-leader-grace-period`.
• Added new startup options `--cache.ideal-lower-fill-ratio` and `--cache.ideal-upper-fill-ratio` to control the minimum and maximum fill ratios for cache tables that trigger shrinking and growing of the table by the cache rebalancer.
