Labeled Events in Custom Events

Description: Labeled events can now be used in custom events as well as inline custom events on charts. Why: As part of the continued push for autotrack, labeled events deserve to be more of a first class citizen in Amplitude - customers aren't going to understand the nuance that a labeled event is a custom event "under the hood".

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.

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.
