- [NEW] Override `dict.get` method for `CouchDatabase` to add `remote…

…` parameter allowing it to

  retrieve a remote document if specified.
- [FIXED] Fixed the documentation for `bookmarks`.
- [FIXED] Also exit `follow_replication` for `failed` state.
- [FIXED] Fixed result paging for grouped view queries.
- [FIXED] Incorrect use of username as account name in `Cloudant.bluemix()`.
- [FIXED] Use custom encoder (if provided) for all view `key` params not just `keys`.
- [FIXED] Support boolean type for `key`, `endkey`, and `startkey` in view requests.
- [DEPRECATED] This library is now deprecated and will be EOL on Dec 31 2021.
- [REMOVED] Removed Python 2 compatibility from the supported environments.
- [IMPROVED] Documented use of `None` account name and url override for `Cloudant.iam()`.
- [IMPROVED] - Document IDs and attachment names are now rejected if they could cause an unexpected
  Cloudant request. We have seen that some applications pass unsantized document IDs to SDK functions
  (e.g. direct from user requests). In response to this we have updated many functions to reject
  obviously invalid paths. However, for complete safety applications must still validate that
  document IDs and attachment names match expected patterns.

- [FIXED] Set default value for `partitioned` parameter to false when…

… creating a design document.

- [FIXED] Corrected setting of `partitioned` flag for `create_query_index` requests.
- [FIXED] Added a workaround for installation on Python 2.

- [FIXED] Correctly raise exceptions from `create_database` calls.

- [FIXED] Fix `DeprecationWarning` from `collections`.
