Release Notes

Latest updates and changes to Blocks

v1.2.15

REST API

• REST API Release - Blocks now includes a REST API for creating sessions, polling replies, and sending follow-ups from your own apps. Start with the REST API Quick Start, then create a session with a request like:

curl -X POST https://api.blocks.team/rest/v1/sessions \
  -H "Authorization: ApiKey $BLOCKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"agent_name":"claude","message":"Summarize the latest PR activity."}'

• Improved Linear Session Naming - Linear-linked sessions now get clearer, more consistent names

• Creator Avatars - Sessions now show creator avatars so it is easier to see ownership at a glance
