 - Built access level labels from their bits instead of a fixed table of combinations, so a level the server adds later is labelled too. A project level (bit 16 and up) is named after the project as the server reports it to its members, e.g. `Brain/MINDS 2.0 Open`, and otherwise `Project<n> Open`. A restrict network other than CBS is `Restrict<n> Open`; `0x0200`, formerly `5Kikan Open`, is now `Restrict2 Open`.
 - `chacl` takes keys built the same way: `cbs_or_pw_open`, `project0_open` and so on. `5kikan_open` is no longer accepted. Its help lists them, an invalid level lists the projects the user belongs to with their keys, and `public` and `storage`, which the server refuses, are refused before any request.
 - `ls` asks the server for the user's projects once per run when logged in.
+- Raised the minimum version of `pydantic` to 2.14.3, and of the development tools `black`, `flake8`, `isort` and `pyright` to their current releases.
 - Removed `FolderAccessLevel.ACCESS_LEVELS` and `FolderAccessLevelItem`. `FolderSimple.access_level_label()` labels a level with the project names given to it.
