This allows resuming ``smoosh`` operations after a node + restart. This is disabled by default and can be enabled with ``[smoosh] persist + = true``. + +* :ghissue:`3798`: Add ``libicu`` version and collation algorithm version to + ``/_node/_local/_versions``. + +* :ghissue:`3837`: The Erlang source tree is now auto-formatted with ``erlfmt``. + +* :ghissue:`3845`: Clean up the ``couch_ejson_compare`` C-module and squash + Microsoft compiler warnings. + +* :ghissue:`3832`: Add ``GET`` variant to ``_dbs_info`` endpoint, used to be + ``POST`` only. + +* :ghissue:`3864`: Improve ``erlang_ls`` configuration. + +* :ghissue:`3853`: Remove legacy ``ddoc_cache_opener`` gen_server and speed up + event routing. + +* :ghissue:`3879`: Remove use of ``ERL_OPTS`` environment variable. All + supported Erlang version now use ``ERL_COMPILER_OPTIONS`` for the same + purpose. + +* :ghissue:`3883`: Add support for SpiderMonkey 91. + +* :ghissue:`3889`: Track ``libicu`` collator versions in the view header. + +* :ghissue:`3952`: Make the timeout for receiving requests from attachment + writers configurable. + +* :ghissue:`3927`: Include index signature in ``_search_info``. + +* :ghissue:`3963`: Optimtize key tree stemming by using maps instead of + sets. This greatly reduced memory usage for heavily conflicted docs in some + situations. + +* :ghissue:`3974`: Create new config options in ``[couchdb]`` and ``[smoosh]`` + sections to enable finer control of compaction logging levels. + +* :ghissue:`3983`, :ghissue:`3984`, :ghissue:`3985`, :ghissue:`3987` + :ghissue:`4033`: Add various functions to ``couch_debug`` module. + +* :ghissue:`4000`: Ensure ``Object.prototype.toSource()`` is always available. + +* :ghissue:`4018`: Update ``jiffy`` to 1.1.1 and ``b64url`` to 1.0.3. + +* :ghissue:`4021`: Reduce smoosh compaction log level to ``debug``. + +* :ghissue:`4041`: Allow and evaluate nested json claim roles in JWT token. + +* :ghissue:`4060`: Add support for Erlang 25. + +* :ghissue:`4064`: Enable replicating purge requests between nodes. Also avoid + apploying interactive purges more than once. + +* :ghissue:`4069`, :ghissue:`4084`: Drop support for Erlang < 23, update + ``vm.args`` settings to match. Review this if you have customized your + ``vm.args``. + +* :ghissue:`4083`: Support Elixir 13. + +* :ghissue:`4085`: Add an option to let ``custodian`` always use ``[cluster] n`` + value. + +* :ghissue:`4095`: Implement `winning_revs_only` option for the replicator. It + replicates only the winning revisions from the source to the target, + effectively discarding conflicts. + +* :ghissue:`4135`: Separate search IO from file IO. + +* :ghissue:`4140`, :ghissue:`4162`: Upgrade hash algorithm for cookie auth (sha1 + -> sha256). This introduces a new config setting ``hash_algorithms``. New cookie + values are hashed with sha256, sha1 hashes are still accepted. Admins can set + this to sha256 only. Sha1 will be disallowed in the next major release. Show + supported hash algorithms in ``/_node/_local/_versions`` endpoint. + +* :ghissue:`4179`: Don't double-encode changes sequence strings in the + replicator. + +* :ghissue:`4182`: Explicitly maintain a fully connected cluster. Previously, it + was possible for the nodes to disconnect, and for that state to persist util + the nodes restarted. + +* :ghissue:`4198`: Redact passwords in log file. + +* :ghissue:`4243`: Update ``mochiweb`` to 3.1.1. + +* :ghissue:`4254`: The ``_dbs_info`` access control is now configured with the + ``[couchdb] admin_only_all_dbs`` setting. Defaults to true. This was a + leftover from the 3.0.0 release. + +Performance +----------- + +* :ghissue:`3860`: Add sharding to ``couch_index_server``, similar to + :ghissue:`3366`:, avoids processing bottlenecs on servers with a lot of + concurrent view indexing going on. + +* :ghissue:`3891`: Avoid decoding JWT payloads when not necessary. + +* :ghissue:`4031`: Default ``[rexi] use_kill_all`` to ``true``. This improves + intra-cluster-node messaging. Set to false if you run a cluster with nodes + tthat have a version <3.0.0. + +* :ghissue:`4052`: Optimize ``couch_util:reorder_results/2,3``, which speeds up + ``_bulk_docs`` and ``_revs_diff``. + +* :ghissue:`4055`: Avoid using ``length/1`` guard for ``>0`` or ``==0`` tests in + ``couch_key_tree``. + +* :ghissue:`4056`: Optimize ``couch_key_tree:find_missing/2``. This speeds up + ``_revs_diff``. + +* :ghissue:`4059`: Reduce complexity of ``possible_ancestors`` from quadratic to + linear. This speeds up working with heavily conflicted documents + significantly. + +* :ghissue:`4091`: Optimize ``couch_util:to_hex/1``, this speeds up all + operations that need to encode a revision id into JSON (this is most + operations). + +* :ghissue:`4106`: Set ``io_priority`` in all IO paths. Introduces ``system`` + ``io_priority``. + +* :ghissue:`4144`, :ghissue:`4172`: Implement ``_bulk_get`` support for the + replicator. Backward compatibility is ensured. This speeds up all + replications. Add option to disable new behaviour for legacy setups. + +* :ghissue:`4163`: Statistically skip ``_revs_diff`` in the replicator. This + improves performance for replications into empty targets. + +* :ghissue:`4177`: Remove the long deprecated ``bigcouch 0.4`` change sequence + support. + +* :ghissue:`4238`: Optimize ``_bulk_get`` endpoint. This speeds up replication + of 1M docs by ~2x. Individual ``_bulk_get`` requests are up to 8x faster. + +Bugfixes +-------- + +* :ghissue:`3817`: Fix undefined function call in ``weatherreport``. + +* :ghissue:`3819`: Return ``400`` instead of ``500`` response code for known + invalid ``_bulk_docs`` with ``new_edits=false`` request. + +* :ghissue:`3861`: Add ``SameSite`` setting when clearing session cookies. + +* :ghissue:`3863`: Fix custom TLS distribution for Erlang 20. + +* :ghissue:`3870`: Always send all cookie attributes. + +* :ghissue:`3886`: Avoid changes feed rewind after shard move with no subsequent + db updates. + +* :ghissue:`3888`: Make ``_stats`` endpoint resilient against nodes that go + offline. + +* :ghissue:`3901`: Use db-creation time instead of ``0`` for + ``instance_start_time`` to help replicator recognise whether a peer database + was deleted and recreated. + +* :ghissue:`3909`: Fix ``new_edits:false`` and VDU ``function_clause``. + +* :ghissue:`3934`: Fix ``replicated_changes`` typo for purge doc updates. + +* :ghissue:`3940`: Ensure the multipart parser always monitors the worker and + make sure to wait for attachment uploads before responding. + +* :ghissue:`3950`: Ignore responses from timed-out or retried ``ibrowse`` calls. + +* :ghissue:`3969`: Fix ``skip`` and ``limit`` for ``_all_dbs`` and + ``_dbs_info``. + +* :ghissue:`3979`: Correctly respond with a ``500`` code when document updates + time out under heavy load. + +* :ghissue:`3992`: Show that Search is available if it was available + before. Avoid Search availability disappearing just because a Search node was + temporarily not available. + +* :ghissue:`3993`: Return a ``400`` error when decoding a JWT token fails, + rather htan crashing and not responding at all. + +* :ghissue:`3990`: Prevent creation of ddocs with no name through Mango index + creation. + +* :ghissue:`4003`: Improve index building during shard splitting. + +* :ghissue:`4016`: Fix ``function_clause`` error for replicated changes with a + target VDU. + +* :ghissue:`4020`: Fix ``maybe_handle_error`` clauses. + +* :ghissue:`4037`: Fix ES{256,384,512} support for JWTs. + +* :ghissue:`4040`: Handle ``exit(shutdown)`` error in ``chttpd``. + +* :ghissue:`4043`: Fix purge request timeouts (5s -> infinity). + +* :ghissue:`4146`: The ``devcontainer`` has been updated. + +* :ghissue:`4050`: Handle ``all_dbs_active`` in ``fabric_doc_update``. + +* :ghissue:`4160`: Return a proper ``400`` error when an invlaid object is sent Review Comment: ```suggestion * :ghissue:`4160`: Return a proper ``400`` error when an invalid object is sent ``` -- This is an automated message from the Apache Git Service.
