+features:
+ - |
+ Added container sharding, an operator controlled feature that
+ may be used to shard very large container databases into a
+ number of smaller shard containers. This mitigates the issues
+ with one large DB by distributing the data across multiple
+ smaller databases throughout the cluster. Please read the full
+ overview at
+ https://docs.openstack.org/swift/latest/overview_container_sharding.html
+
+ - |
+ Provide an S3 API compatibility layer. The external "swift3"
+ project has been imported into Swift's codebase as the "s3api"
+ middleware.
+
+ - |
+ Added "emergency mode" hooks in the account and container replicators.
+ These options may be used to prioritize moving handoff
+ partitions to primary locations more quickly. This helps when
+ adding capacity to a ring.
+
+ - Added ``-d <devs>`` and ``-p <partitions>`` command line options.
+
+ - Added a handoffs-only mode.
+
+ - |
+ Add a multiprocess mode to the object replicator. Setting the
+ ``replicator_workers`` setting to a positive value N will result
+ in the replicator using up to N worker processes to perform
+ replication tasks. At most one worker per disk will be spawned.
+
+ Worker process logs will have a bit of information prepended so
+ operators can tell which messages came from which worker. The
+ prefix is "[worker M/N pid=P] ", where M is the worker's index,
+ N is the total number of workers, and P is the process ID. Every
+ message from the replicator's logger will have the prefix
+
+ - |
+ The object reconstructor will now fork all available worker
+ processes when operating on a subset of local devices.
+
+ - |
+ Add support for PROXY protocol v1 to the proxy server. This
+ allows the Swift proxy server to log accurate client IP
+ addresses when there is a proxy or SSL-terminator between the
+ client and the Swift proxy server. Example servers supporting
+ this PROXY protocol include stunnel, haproxy, hitch, and
+ varnish. See the sample proxy server config file for the
+ appropriate config setting to enable or disable this
+ functionality.
+
+ - |
+ In the ratelimit middleware, account whitelist and blacklist
+ settings have been deprecated and may be removed in a future
+ release. When found, a deprecation message will be logged.
+ Instead of these config file values, set X-Account-Sysmeta-
+ Global-Write-Ratelimit:WHITELIST and X-Account-Sysmeta-Global-
+ Write-Ratelimit:BLACKLIST on the particular accounts that need
+ to be whitelisted or blacklisted. System metadata cannot be added
+ or modified by standard clients. Use the internal client to set sysmeta.
+
+ - |
+ Add a ``--drop-prefixes`` flag to swift-account-info,
+ swift-container-info, and swift-object-info. This makes the
+ output between the three more consistent.
+
+ - |
+ statsd error messages correspond to 5xx responses only. This
+ makes monitoring more useful because actual errors (5xx) will
+ not be hidden by common user requests (4xx). Previously, some 4xx
+ responses would be included in timing information in the statsd
+ error messages.
+
+ - |
+ Truncate error logs to prevent log handler from running out of buffer.
+
+ - |
+ Updated requirements.txt to match global exclusions and formatting.
+
+ - |
+ tempauth user names now support unicode characters.
+
+ - |
+ Various other minor bug fixes and improvements.
