Rasa_Sdk 3.18.1 (2026-09-24)

Improvements

• #1408: The rasa/rasa-sdk Docker image is now built on Ubuntu 24.04 with Python 3.12, aligning the action-server image with Rasa Pro 3.18+. The supported Python range for the rasa-sdk package itself is unchanged (>=3.10,<3.15).

Bugfixes

• #1412: Bumped multidict from 5.2.0 to 6.9.1. The old pin has no prebuilt wheel for Python 3.12 and fails a PEP 517 source build (missing compiler in the published Docker image), which blocked building the rasa/rasa-sdk image on the Ubuntu 24.04 / Python 3.12 base used to align with Rasa Pro 3.18+. main already carries this fix (originally #1294); this backports it to this release line.
