## 4.0.3
  - When configuring the `canned_acl` options of the plugins the role was not applied correctly to the created object: #7

## 4.0.2
  - Fixed AWS authentication when using instance profile credentials.

## 4.0.1
  - Improved Error logging for S3 validation. Now specific S3 perms errors are logged

## 4.0.0
  - This version is a complete rewrite over version 3.0.0 See #103
  - This Plugin now uses the V2 version of the SDK, this make sure we receive the latest updates and changes.
  - We now uses S3's `upload_file` instead of reading chunks, this method is more efficient and will uses the multipart with threads if the files is too big.
  - You can now use the `fieldref` syntax in the prefix to dynamically changes the target with the events it receives.
  - The Upload queue is now a bounded list, this options is necessary to allow back pressure to be communicated back to the pipeline but its configurable by the user.
  - If the queue is full the plugin will start the upload in the current thread.
  - The plugin now threadsafe and support the concurrency model `shared`
  - The rotation strategy can be selected, the recommended is `size_and_time` that will check for both the configured limits (`size` and `time` are also available)
  - The `restore` option will now use a separate threadpool with an unbounded queue
  - The `restore` option will not block the launch of logstash and will uses less resources than the real time path
  - The plugin now uses `multi_receive_encode`, this will optimize the writes to the files
  - rotate operation are now batched to reduce the number of IO calls.
  - Empty file will not be uploaded by any rotation rotation strategy
  - We now use Concurrent-Ruby for the implementation of the java executor
  - If you have finer grain permission on prefixes or want faster boot, you can disable the credentials check with `validate_credentials_on_root_bucket`
  - The credentials check will no longer fails if we can't delete the file
  - We now have a full suite of integration test for all the defined rotation

Fixes: #4 #81 #44 #59 #50

## 3.2.0
  - Move to the new concurrency model `:single`
  - use correct license identifier #99
  - add support for `bucket_owner_full_control` in the canned ACL #87
  - delete the test file but ignore any errors, because we actually only need to be able to write to S3. #97

## 3.1.2
  - Fix improper shutdown of output worker threads
  - improve exception handling

## 3.0.1
 - Republish all the gems under jruby.

## 3.0.0
 - Update the plugin to the version 2.0 of the plugin api, this change is required for Logstash 5.0 compatibility. See https://github.com/elastic/logstash/issues/5141

## 2.0.7
 - Depend on logstash-core-plugin-api instead of logstash-core, removing the need to mass update plugins on major releases of logstash

## 2.0.6
 - New dependency requirements for logstash-core for the 5.0 release

## 2.0.5
 - Support signature_version option for v4 S3 keys

## 2.0.4
 - Remove the `Time.now` stub in the spec, it was conflicting with other test when running inside the default plugins test #63
 - Make the spec run faster by adjusting the values of time rotation test.

## 2.0.3
 - Update deps for logstash 2.0

## 2.0.2
 - Fixes an issue when tags were defined #39

## 2.0.0
 - Plugins were updated to follow the new shutdown semantic, this mainly allows Logstash to instruct input plugins to terminate gracefully,
   instead of using Thread.raise on the plugins' threads. Ref: https://github.com/elastic/logstash/pull/3895
 - Dependency on logstash-core update to 2.0

## 1.0.1
- Fix a synchronization issue when doing file rotation and checking the size of the current file
- Fix an issue with synchronization when shutting down the plugin and closing the current temp file
