What is CircleCI?

CircleCI is rebuilding its API for agents and retiring the 1.0-era surface beneath it.

CircleCI shipped API v3 this week with uniform conventions (UUID resource IDs, cursor pagination, one error format, standard rate-limit headers) and named AI agents as a target consumer. The same week it set a hard February 1, 2027 removal for ten v1/v1.1 trigger and rerun endpoints, and made Slack approval notifications actionable. These sit on top of September's open preview for running GitHub Actions YAML on CircleCI compute.

What is Keycloak?

Keycloak patches its 26.4 and 26.6 lines in lockstep; the tags carry no notes.

The tracked Keycloak entries are version-set commits for two supported lines, 26.4.x and 26.6.x, cut on the same day in August and again in September. The release feed carries only the version bump, so the fixes inside each patch aren't visible here.

CircleCI is rebuilding its API for agents and retiring the 1.0-era surface beneath it.

◆ Current state

CircleCI shipped API v3 this week with uniform conventions (UUID resource IDs, cursor pagination, one error format, standard rate-limit headers) and named AI agents as a target consumer. The same week it set a hard February 1, 2027 removal for ten v1/v1.1 trigger and rerun endpoints, and made Slack approval notifications actionable. These sit on top of September's open preview for running GitHub Actions YAML on CircleCI compute.

◆ Where it's heading

The pattern is consolidation plus new entry points. Legacy surfaces are being cut (v1 endpoints, Bitbucket Data Center, old Xcode images) while new ways in are added: GHA YAML for migrants, v3 for programmatic and agent clients, Slack for approvals. CircleCI is trying to be reachable from wherever the work is triggered, not only from its own config and web app.

◆ Prediction

Expect v3 coverage to expand endpoint by endpoint, with v2 deprecation notices following once parity is reached; the GHA YAML preview is the other likely next step, most plausibly adding non-Linux runners or secret import.

0.0

Keycloak patches its 26.4 and 26.6 lines in lockstep; the tags carry no notes.

◆ Current state

The tracked Keycloak entries are version-set commits for two supported lines, 26.4.x and 26.6.x, cut on the same day in August and again in September. The release feed carries only the version bump, so the fixes inside each patch aren't visible here.

◆ Where it's heading

Keycloak is maintaining two release lines in parallel with roughly monthly patch drops. Without notes in the feed, the entries show cadence and support policy, not product direction.

◆ Prediction

Another paired 26.4/26.6 patch release around early October fits the monthly pattern; the entries don't show what features are in development.
