What is Drone CI?

Drone now ships as Harness Open Source, and its releases are mostly code-hosting features.

The feed tracked for Drone CI is the Harness Open Source repository, which absorbed Drone. Its two visible releases are about Git hosting, not pipelines: v3.2.0 added Git LFS, default reviewers through branch rules, PR retargeting and a revert option, and v3.3.0 in August 2025 added tag rules, a PR dashboard with favorite repositories, and a fix for a Git LFS upload path-traversal issue.

What is Harbor?

Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.

Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.

Drone now ships as Harness Open Source, and its releases are mostly code-hosting features.

◆ Current state

The feed tracked for Drone CI is the Harness Open Source repository, which absorbed Drone. Its two visible releases are about Git hosting, not pipelines: v3.2.0 added Git LFS, default reviewers through branch rules, PR retargeting and a revert option, and v3.3.0 in August 2025 added tag rules, a PR dashboard with favorite repositories, and a fix for a Git LFS upload path-traversal issue.

◆ Where it's heading

Drone's identity is being folded into a broader Harness platform that combines code hosting, review and CI. Recent work brings branch- and tag-protection rules and review workflows up to GitHub and GitLab standards. Nothing in these entries concerns Drone's pipeline engine directly.

◆ Prediction

With only two releases, three months apart, visible, the cadence is unclear. If it continues, expect more repository governance and PR workflow features rather than CI changes.

Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.

◆ Current state

Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.

◆ Where it's heading

The 2.16 line shifts Harbor from patching toward enterprise registry features: finer RBAC, deeper audit trails, and a proxy cache that handles OCI referrers such as signatures and SBOMs. Multi-arch builds make Harbor a straightforward fit for arm64 clusters. Security fixes keep landing alongside, so the 2.14 and 2.15 patch lines will likely continue.

◆ Prediction

Expect further 2.16.0 release candidates before GA, plus more 2.14.x and 2.15.x patch tags. Whether custom roles get a matching API-level story is not yet clear from these notes.
