# Rasa Pro Services Changelog All notable changes to Rasa Pro Services will be documented in this page. This product adheres to [Semantic Versioning](https://semver.org/) starting with version 3.3 (initial version). ## [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 **Rasa Pro Services 3.8.1 (2026-04-17)** ### Bugfixes - Updated the following Poetry dependencies with vulnerability patches: - `requests` to `2.33.1` fixing CVE-2026-25645. - `cryptography` to `46.0.7` fixing CVE-2026-39892. - `setuptools` to `82.0.1` Additionally, updated pip installed in Dockerfile to `==26.x` fixing CVE-2026-24049 vulnerability in `wheel` and updated `setuptools` to the version locked in `poetry.lock` which updated `jaraco.context` dependency to `6.1.0` fixing CVE-2026-23949. ## [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 - Implement custom timestamp type inheriting from `sqlalchemy.types.TypeDecorator`. This custom type normalizes and denormalizes timestamp columns across all db tables to ensure consistent timezone handling during inserting and querying. ## [3.6.1] - 2025-10-29 **Rasa Pro Services 3.6.1 (2025-10-29)** ### Bugfixes - Catch all exceptions raised during DialogueStackUpdated event processing and skip the event if an exception occurs. ## [3.6.0] - 2025-10-10 **Rasa Pro Services 3.6.0 (2025-10-10)** ### Features - Add support for IAM authentication for AWS RDS database in the analytics service. - Add support for IAM authentication for AWS Managed Streaming for Apache Kafka in the analytics service. ### Improvements - Add new environment variables for each AWS service integration that indicates whether to use IAM authentication. ### Bugfixes - Refactor the logic for creating new sessions. ## [3.5.10] - 2025-11-25 **Rasa Pro Services 3.5.10 (2025-11-25)** ### Bugfixes - Implement custom timestamp type inheriting from `sqlalchemy.types.TypeDecorator`. ## [3.5.9] - 2025-10-29 **Rasa Pro Services 3.5.9 (2025-10-29)** ### Bugfixes - Catch all exceptions raised during DialogueStackUpdated event processing and skip the event if an exception occurs. ## [3.5.8] - 2025-10-10 **Rasa Pro Services 3.5.8 (2025-10-10)** ### Bugfixes - Refactor the logic for creating new sessions. ## [3.5.7] - 2025-10-06 **Rasa Pro Services 3.5.7 (2025-10-06)** ### Bugfixes - Add the installation of `zlib` OS dependency to Analytics Dockerfile to fix build issues when running the service. ## [3.5.6] - 2025-09-11 **Rasa Pro Services 3.5.6 (2025-09-11)** ### Bugfixes - Upgrade alpine base image to 3.19 in order to a security vulnerability in alpine:3.17. ## [3.5.5] - 2025-09-03 **Rasa Pro Services 3.5.5 (2025-09-03)** ### Bugfixes - Upgrade vulnerabilities. ## [3.5.4] - 2025-07-29 **Rasa Pro Services 3.5.4 (2025-07-29)** ### Bugfixes - Upgrade the following dependencies to fix security vulnerabilities in the analytics service. ## [3.5.3] - 2025-06-27 **Rasa Pro Services 3.5.3 (2025-06-27)** ### Bugfixes - Handle `JsonPatchConflict` exceptions gracefully when loading pre-existing dialogue stack events or when applying current event patches. ## [3.5.2] - 2025-05-21 **Rasa Pro Services 3.5.2 (2025-05-21)** ### Bugfixes - Fixed a bug in Rasa Analytics for Session Creation Logic.
