   were specified. Should the sharding keys not match the values in the actual document
   a not found error will be returned.
 
+* Bugfix: In an AQL cluster query, when gathering unsorted data in combination
+  with a LIMIT with non-zero offset, if this offset exactly matches the number
+  of documents in the first shards consumed, the rest of the documents was not
+  returned.
+
+* Show shards of all collections (including system collections) in the web UI's shard
+  distribution view.
+
+  This is necessary to access the prototype collections of a collection sharded via
+  `distributeShardsLike` in case the prototype is a system collection, and the prototype
+  should be moved to another server.
+
+* RCLone URL normalization
+
+* Fixed Unintended multiple unlock commands from coordinator to
+  transaction locked db servers
+
+* Disallow using `_id` or `_rev` as shard keys in clustered collections.
+
+  Using these attributes for sharding was not supported before, but didn't trigger
+  any errors. Instead, collections were created and silently using `_key` as
+  the shard key, without making the caller aware of that an unsupported shard
+  keys was used.
+
+* DB server locking / unlocking for hot backup revisited and enhanced.
+
+* Fixed unintended multiple unlock commands from coordinator to
+  transaction locked db servers.
+
+* Use execvp instead of execv in hotbackup restore.
+
+* Re-enabled the AQL sort-limit optimization rule in conjunction with fullCount
+  in the cluster. It now also may speed up fullCount with sorted indexes and a
+  limit.
+
+* Fix config directory handling, so we don't trap into UNC path lookups on windows
+
+* Prevent spurious log message "Scheduler queue is filled more than 50% in last x s"
+  from occurring when this is not the case. Due to a data race, the message could
+  previously also occur if the queue was empty.
+
+* Make the scheduler enforce the configured queue lengths. The values of the options
+  `--server.scheduler-queue-size`, `--server.prio1-size` and `--server.maximal-queue-size`
+  will now be honored and not exceeded.
+
+  The default queue sizes in the scheduler for requests buffering have
+  also been changed as follows:
+
+      request type        before      now
+      -----------------------------------
+      high priority          128     4096
+      medium priority    1048576     4096
+      low priority          4096     4096
+
+  The queue sizes can still be adjusted at server start using the above-
+  mentioned startup options.
+
+* Fix compilation issue with clang 10
+
+* Fixed issue #10062: AQL: Could not extract custom attribute.
+
+* Add replicationFactor, minReplicationFactor and sharding strategy to database creation
+  dialog in web UI. Preselect database default values for collection creation in web UI.
+
+* Add new JavaScipt function `db._properties()` and REST route GET
+  `/_api/database/properties` that provides information about the current database's
+  properties.
+
+* Add new options `sharding` and `replicationFactor` for database creation methods. The
+  specified values will provide the defaults for all collections created in a database.
+
+  Valid values for `sharding` are `""`, "flexible", "single". The first 2 values are
+  treated equally. Values for `replicationFactor` are natural numbers or the string
+  `satellite`.
+
+* Add new server option `--cluster.default-replication-factor` that allows to set the
+  default replication factor for non-system collections (default: 1).
+
+* Made the mechanism in the Web UI of replacing and upgrading a foxx app more clear.
+
+* Fix a problem with AQL constrained sort in the cluster, which might abort
+  queries.
+
+* Fix strange shutdown hanger which came from the fact that currently
+  libgcc/libmusl wrongly detect multi-threadedness in statically linked
+  executables.
+
+* Enabled IPO with cmake as an option, default is on for release builds without
+  google tests.
+
+* Bugfix: The AQL sort-limit optimization was applied in some cases it shouldn't, 
+  resulting in undefined behaviour.
+
+* Remove operations for documents in the cluster will now use an optimization, 
+  if all sharding keys are specified. Should the sharding keys not match the values in 
+  the actual document, a not found error will be returned.
+
 * Fixed AQL constrained-heap sort in conjunction with fullCount.
 
 * Fixed "ArangoDB is not running in cluster mode" errors in active failover setups.
