Modal 1.3.0
Modal now supports Python 3.14. Python 3.14t (the free-threading build) support is currently a work in progress, because we are waiting for dependencies to be updated with free-threaded support. Additionally, Modal no longer supports Python 3.9, which has reached end-of-life.

Streaming transformation (special property) improvements
Description: After reviewing 2025 customer tickets, the team identified a significant concentration of issues related to streaming transformation limitations around special properties. To improve customer experience and reduce support load, we prioritized a set of improvements and clarifications in Q4.
General destinations page and event streaming improvements
Description: We've leveraged our principle of customer centricity, and taken a look at recent customer tickets in the event streaming area. For each category of tickets we saw, we identified a couple of improvements to be made and, well, made them.
AI Controls + Org-Level AI Context
Description: We’ve added a new tab, AI Controls, in org settings that will be the new home for Amplitude AI configs, context management, and enterprise AI controls (in the future!). The first feature in AI Controls is an AI Context input which lets customers provide org-level context to Ask AI and Agents.
Capture Session Replays via the Chrome Extension
Description: You can now capture Session Replays directly from the Amplitude Chrome extension, no code changes required. By enabling Session Replay in Event Test Mode, you can instantly record and inspect real user experiences on any site that supports Session Replay. This is a powerful way to test run Session Replay without contacting a developer.
Improved SR querying - users can view all (or at least way more) of their replays
Description: This has to be one of the most impactful improvements that we will ever deliver for Session Replay customers. Without doing anything, customers are now able to view anywhere from 1.1-10000x more replays than they could before. Previously, to surface a replay, the session ID on the replay had to match at least one event's session ID.
Default Threshold for Session Replay List
A default threshold of 10 seconds has been implemented for the session replay list. This change is a significant quality of life improvement for organizations that collect very short replays. Who: Live for all organizations. Why: No one wants to see 0s or 1s replays.
Annotations Rest API (v3) and additional improvements
Description: We added new REST API endpoints to manage annotation categories and access new annotation fields (like end date). HC Docs have been updated with the new API. Quality of life improvement: allow bulk copying annotations across projects (from the manage annotations table in project settings). This was a requested feature.
