2.4.1 (2020-03-06)

• [IMPROVED] Record checkpoint on empty _changes result in pull replications. This change optimizes
  filtered replications when changes in remote database doesn't match the replication filter.
• [UPGRADED] Upgraded to version 2.19.0 of the cloudant-http library.

2.4.0 (2019-01-15)

• [NEW] Database methods read, contains, create, and delete now accept local (non-replicating documents). These documents must have their document ID prefixed with _local/ and must have their revision ID set to null (where applicable).
• [FIXED] Fixed purge_seq to return a String object when replicating with CouchDB 2.3 databases.

2.3.0 (2018-08-14)

• [NEW] Added API for specifying a list of document IDs in the filtered pull replicator.
• [IMPROVED] Forced a TLS1.2 SSLSocketFactory where possible on Android API versions < 20 (it is already enabled by default on newer API levels).

2.2.0 (2018-02-14)

• [NEW] Added API for specifying a mango selector in the filtered pull replicator
• [IMPROVED] Improved efficiency of sub-query when picking winning revisions. This improves performance when inserting revisions, including during pull replication.
• [UPGRADED] Upgraded to version 2.12.0 of the cloudant-http library.

2.1.0 (2017-12-04)

• [NEW] Added API for upcoming IBM Cloud Identity and Access
  Management support for Cloudant on IBM Cloud. Note: IAM API key
  support is not yet enabled in the service.
• [IMPROVED] Updated documentation by replacing deprecated links with the latest Bluemix or CouchDB links.
• [IMPROVED] Added seq_interval to improve Changes API throughput when replicating from
  a CouchDB 2.x endpoint.
• [UPGRADED] Upgraded to version 2.11.0 of the cloudant-http library.

2.0.2 (2017-06-20)

• [FIXED] Removed cloudant-sync-datastore-android project dependency
  on com.google.android:android. This dependency was inadvertently
  made a run-time dependency where it should have been a build-time
  dependency.

2.0.1 (2017-04-26)

• [IMPROVED] Increased the resilience of replication to network failures.
• [FIXED] NPE when accessing indexes created in earlier versions that were
  migrated to version 2.
• [FIXED] Exception fetching attachments on a deleted revision.

  been lost.

2.0.0 (2017-02-07)

• [BREAKING CHANGE] With the release of version 2.0 of the library,
  there are a large number of breaking changes to package names,
  classes and methods. API users will need to make changes to their
  existing code in order to use this version of the library. Consult
  the migration guide for a comprehensive list of
  changes and suggested strategies to migrate your code.
• [BREAKING CHANGE] The name field has been removed from
  Attachment. Additionally, the name argument has been removed
  from the UnsavedStreamAttachment constructors. The name of the
  attachment is the key used to add or retrieve the attachment to or
  from the attachments map.
• [IMPROVED] DocumentStore.getInstance() will try to create all
  necessary sub-directories in order to construct the path represented
  by the File argument. This differs from the behaviour of the 1.x
  versions of the library which would only attempt to create one level
  of directories.
• [REMOVED] The batchLimitPerRun property has been removed from the
  Pull and Push replicator builders. There is no limit to the number
  of batches in a replicator run - the replicator will run to
  completion unless an error occurs.
• [IMPROVED] Removed limitation on DocumentStore names. Under the
  old Datastore API, the directory containing the SQLite database
  had to conform to the CouchDB database name restrictions. This no
  longer applies.
• [NOTE] The "CRUD Guide" markdown document (previously located in
  doc/crud.md) has been migrated to a
  java source file.
• [NEW] advanced() getter on DocumentStore for specialist advanced use cases.
  Adds support for creating specific document revisions with history.
• [FIXED] Issue with double encoding of restricted URL characters in credentials when using
  ReplicatorBuilder.
• [FIXED] Issue where push replicating a large number of attachments
  could exhaust the operating system file handle limit, on some
  platforms.
• [FIXED] Issue querying indexed fields when combining the $not and
  $size operators.

1.1.5 (2016-12-08)

• [FIXED] Issue where replicator would not get the latest revision if _bulk_get
  was available.

1.1.4 (2016-11-23)

• [FIXED] Issue performing cookie authentication in version 1.1.3.
