What is CircleCI?

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

What is Terragrunt?

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

7.5

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

◆ Current state

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

◆ Where it's heading

The platform keeps pulling identity and permission checks onto the real actor: scoped tokens, V3 OIDC claims and re-run attribution. The self-hosted line follows with its own permission and link repairs. Server 5.0 is taking shape as a breaking release, at least for secret storage.

◆ Prediction

Expect more Server 4.x patches ahead of 5.0, with Tink migration guidance repeated until Vault support ends.

5.0

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

◆ Current state

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

◆ Where it's heading

The graduation model has repeated at a larger scale: six experiments in v1.1, eleven in v1.2. The candidates ran as stabilization, with fixes concentrated in the CAS, the catalog and the Provider Cache Server. Each breaking change also ships with an escape hatch, base64gzip_compat() or enable_bucket_root_access, which shows how seriously the project treats its 1.0 guarantees.

◆ Prediction

v1.2.0 final is the next release, since rc3 says only regression or urgent fixes will land first. It has not appeared in this feed in the 18 days since rc3.
