2.13.0

Bug fixes

• Fixes duplicated records in paginated results when limit is forced via
  settings (fixes #588)

New features

• Allow to keep the last_modified field of records when updating or
  creating them. Useful for replication of remote collections (fixes #604)

Internal changes

• Documentation has been updated to explain better how versionning is
  handled (fixes #603)

2.12.0

Protocol

Minor changes in the root URL (hello view):

• Added http_api_version (#600)
• Renamed hello to project_name
• Renamed protocol_version to cliquet_protocol_version
• Renamed documentation to project_docs
• Renamed version to project_version

Breaking changes

• When using cliquet-fxa, the setting multiauth.policy.fxa.use must now
  be explicitly set to cliquet_fxa.authentication.FxAOAuthAuthenticationPolicy
• Fields in the root view were renamed (#600)

Bug fixes

• Include plugins after setting up components (like authn/authz) so that plugins
  can register views with permissions checking
• Remove __permissions__ from impacted records values in ResourceChanged
  events (#586)

New features

• New options in configuration of listeners to specify filtered actions and
  resource names (#492, #555)
• Add ability to listen to read action on resource (disabled by default)
  (#493)

Internal

• Fixed a few details in quickstart docs since backends are not Redis by default
  anymore
• Replace usage of assert by explicit exceptions since the former can
  be ignored when python is ran with -O (fixes #592)
• Improved documentation about permissions (#572, thanks for the feedback @MrChoclate)
• Fixed docs building under Python 3 (#591)

2.10.3

Bug fixes

• Fix Service CORS not being set when plugins are included
• Fix principals of permission backend not being plugged by default (#573)
• Fix pagination loop when number of records is multiple of page size (fixes #366)
• Fix Redis error traces not being logged (#560)

2.11.0

Protocol

• _since and _before now accepts an integer value between quotes ",
  as it would be returned in the ETag response header.
• A batch request now fails if one of the subrequests fails (#510)
  (see new feature about transactions)

Breaking changes

• For PostgreSQL backends, it is recommended to specify postgresql://.

New features

• A transaction now covers the whole request/response cycle (#510, Kinto/kinto#194).
  If an error occurs during the request processing, every operation performed
  is rolled back. Note: This is only enabled with PostgreSQL backends. In
  other words, the rollback has no effect on backends like Redis or Memory.
• Add the protocol_version to tell which protocol version is
  implemented by the service in the hello page. (#324)
• New settings for backends when using PostgreSQL: *_pool_maxoverflow,
  *_pool_recycle, *_pool_timeout to control connections pool
  behaviour.
• Add custom pool supporting a max_backlog parameter that limits the
  number of threads waiting for a connection (#509)
• Add impacted_records attribute on ResourceChanged event (#501)
  This also allows listeners to react on particular field change, since old and
  new version of records is provided.

Bug fixes

• Fix Service CORS not being set when plugins are included
• Fix crash with Redis backend if record parent/id is unicode (fixes #556)
• Fix principals of permission backend not being plugged by default (#573)
• Fix Redis error traces not being logged (#560)
• Fix principals of permission backend not being plugged by default. (#573)
• Maintain pagination offset to prevent pagination loop in some cases. (#366)

Internal changes

• Switch to SQLAlchemy for smarter connections pools.
• Added a simple end-to-end test on a Cliquet sample application, using
  Loads <http://github.com/loads/>_. (fixes #512)
• Switched to SQLAlchemy sessions instead of raw connections and cursors. (#510)
• Refactor Redis clients instantiation to avoid repeated defaults. (#567, #568)
• Initialize Service class attributes before including plugins. (#578)
• Add a statsd_count helper function to ease the usage of statsd. (#574)
• Mention SQLAlchemy on missing PostgreSQL dependencies. (#545)

Bug fixes

• Fix sharing records with ProtectedResource (fixes #549)
• Fix notifications on protected resources (#548)
• Log any heartbeat exception (fixes #559)
• Fix crash with Redis backend if record parent/id is unicode (fixes #556)
• Fix Redis client instantiation (fixes #564)

2.10.1

Bug fixes

• Make sure read enpoints (GET, OPTIONS, HEAD) are activated in readonly mode. (#539)

2.10.0

Protocol

• Moved userid attribute to a dedicated user mapping in the hello
  view.
• Fixed 503 error message to mention backend errors in addition to unavailability.
• Set cache headers only when anonymous (fixes #449)
• Follow redirections in batch subrequests (fixes #511)
• When recreating a record that was previously deleted, status code is now 201
  (ref #530).

New features

• Follow redirections in batch subrequests (fixes #511)
• Add a readonly setting to run the service in read-only mode. (#525)
• If no client cache is set, add Cache-Control: no-cache by default,
  so that clients are forced to revalidate their cache against the server
  (#522, ref Kinto/kinto#231)

Bug fixes

• Fix PostgreSQL error when deleting an empty collection in a protected
  resource (fixes #528)
• Fix PUT not using create() method in storage backend when tombstone exists
  (fixes #530)
• Delete tombstone when record is re-created (fixes #518)
• Fix crash with empty body for PATCH (fixes #477, fixes #516)
• Fix english typo in 404 error message (fixes #527)

Internal changes

• Better pycache cleaning

2.9.0

New features

• Added Pyramid events, triggered when the content of a resource has changed. (#488)
• Added cliquet.includes setting allowing loading of plugins once Cliquet
  is initialized (unlike pyramid.includes). (#504)

Protocol

• Remove the broken git revision commit field in the hello page. (#495).

Breaking changes

• Renamed internal backend classes for better consistency. Settings
  remain unchanged, but if you imported the backend classes in your
  Cliquet application, it will break (#491).
• cliquet.schema is now deprecated, and was moved to a cliquet.resource
  module. (#505)
• Resource collection attribute is now deprecated. Use model attribute instead. (#506)

Internal changes

  client code. (#491)

  thanks @rodo)

  configure public_settings to expose them (with cliquet. or
  project_name.) (ref #476)
