See [here](https://github.com/kmaehashi/atwiki-python/pulls?q=is%3Apr+milestone%3Av0.0.10+is%3Aclosed) for the list of all pull-requests merged.

* Fixes the issue that `AtWikiAPI.get_tags()` only returns the first 50 pages after the specification change of AtWiki around 2022-09-14. Also improves test suites to better detect such errors.

* **IMPORTANT**: In `AtWikiAPI.get_source()`, `generation` parameter must now be specified as an absolute ID of the revision, instead of a relative count from the latest revision. This change was introduced in AtWiki around 2022-09-14. Be warned that this may break existing code retrieving a source for previous revisions of a page. Code only retrieving the latest revision (by omitting `generation` parameter or passing `generation=0`) will not be affected.
* `AtWikiAPI` now serializes requests to maintain the interval when the instance is shared between threads.

See [here](https://github.com/kmaehashi/atwiki-python/pulls?q=is%3Apr+milestone%3Av0.0.8+is%3Aclosed) for the list of all pull-requests merged.
