### Specific Agenda Items

#### Outstanding issues for 2.0 release ([milestone](https://github.com/aiidateam/aiida-core/milestone/18))

* Last refactorings
* Refactor `Node` methods ([discussion](https://github.com/aiidateam/aiida-core/discussions/5465)): instead of inheriting methods from mixins, the node now has an object (`NodeContext`) to better "containerize" these functions.
* [PR-5439](https://github.com/aiidateam/aiida-core/pull/5439) for `NodeRepositoryMixin`
* [PR-5442](https://github.com/aiidateam/aiida-core/pull/5442) for `EntityAttributesMixin`
* [PR-5445](https://github.com/aiidateam/aiida-core/pull/5445) for `EntityExtrasMixin`
* [PR-5446](https://github.com/aiidateam/aiida-core/pull/5446) for `comments`
* Refactor `AbstractRepositoryBackend` ([issue](https://github.com/aiidateam/aiida-core/issues/5451)): to remove the 'hardcoded' requirement in the `NodeRepository` to use the local filesystem as a temporary sandbox to put files while constructing the node and then store them all at once in the backend repository.
* Not necessary for 2.0
* Last fixes for outstanding problems
* Remove remaining django remnants ([PR #5468](https://github.com/aiidateam/aiida-core/pull/5468))
* The `get_minimum_job_poll_interval` default should be set by the `Transport` plugin instead of the `Computer` instance (an explicit non default value can still be set on the computer) ([PR #5457](https://github.com/aiidateam/aiida-core/pull/5457)).
* Not necessary for 2.0
* Fix the place where the default user is being stored (from the `User` class to the `StorageBackend`) so that it loads the correct one on switching backends ([PR #5460](https://github.com/aiidateam/aiida-core/pull/5460)).
* Reinstate old profile after using the `profile_context` ([PR #5461](https://github.com/aiidateam/aiida-core/pull/5461)).
* Add a validation to check that nodes are from the same backend in `validate_link` ([PR #5462](https://github.com/aiidateam/aiida-core/pull/5462)).
* <https://github.com/aiidateam/aiida-core/pull/5448> ("concolitdates" SQLite backend)
* Last Tests:
* Testing the repository migration and maintainance ([discussion](https://github.com/aiidateam/aiida-core/discussions/5379)) -> Migration seems tested, did people run maintainance?
* Testing the archive migration ([discussion](https://github.com/aiidateam/aiida-core/discussions/5407))
* Finishing details:
* Run the tests with full verbosity to eliminate warnings before releasing ([issue 5282](https://github.com/aiidateam/aiida-core/issues/5282))
* Make sure key external packages/plugins are updated to 2.0 ([issue 5284](https://github.com/aiidateam/aiida-core/issues/5284)): send poll through slack?
* plugin migration script for AiiDA v2.0([issue 5335](https://github.com/aiidateam/aiida-core/issues/5335))
* Event after the release, reach out to advertise just before the release.
