[3.9.0] - 2026-06-29

Rasa Pro Services 3.9.0 (2026-06-29)

Improvements

Added created_at UTC insertion timestamp column and corresponding index to all analytics tables. Added indexes on timestamp and inserted_at where those columns exist.

Bugfixes

Fixed a long-standing bug in the analytics legacy session-detection path that split a single Rasa conversation session into two analytics sessions. action_session_start and the session_started_metadata slot both unconditionally marked a new session, so every Rasa session start produced a first session holding only the events between the two markers and a second session holding the rest. The slot check is now symmetric to the action check and treats the slot as part of an in-flight session start when action_session_start was the most recent anchor event for the sender.
Upgraded versions of urllib3, idna, mako, and redshift-connector and accompanying dependencies because of reported vulnerabilities.
Removed the unused cargo build toolchain, including its bundled rustc source tree, from the production image.

[3.8.1] - 2026-04-17

[3.8.0] - 2026-03-26

Rasa Pro Services 3.8.0 (2026-03-26)

Improvements

Add the ability to disable stack event processing by the analytics service through an environment variable. Set the DISABLE_STACK_EVENT_PROCESSING variable to true to disable analytics stack event processing. By default, stack event processing is enabled.
Add new composite and covering indexes to existing tables in Rasa Analytics to improve the performance of high-load analytics queries and reduce CPU utilization.
Add a new stack event query for the event_was_processed check to handle edge cases when stack events are stored in the rasa_event table but not in the rasa_dialogue_stack_frame table because of being skipped during processing and published to the DLQ.
Update Analytics session processing to use the session_id provided by Rasa Pro 3.16 in event.metadata.session_id directly as the session identifier, replacing the Analytics-generated UUID. A new rasa_user table is introduced to track end users across multiple conversations, populated from the user_id field on Kafka event payloads.

Bugfixes

Upgrade urllib3, werkzeug, and brotli to fix security vulnerabilities.
Update urllib3 to 2.6.3 to address CVE-2026-21441.

[3.7.0] - 2025-11-26

Rasa Pro Services 3.7.0 (2025-11-26)

Improvements

Add the original Rasa event message offset to the header of the message being sent to the Kafka dead-letter-queue. This allows easier tracing of the original message in case of errors.
Allow skipping of db migration run when starting the Analytics service by setting the environment variable RUN_ANALYTICS_DB_MIGRATIONS to "false".
Add database indexes to analytics tables to improve query performance.

[3.6.2] - 2025-11-25

Rasa Pro Services 3.6.2 (2025-11-25)

Bugfixes
