What is Citus?

Citus is in maintenance mode across four branches, with the feature work invisible from the feed.

Citus is the Postgres extension that shards tables across a cluster, and its release feed right now is almost entirely branch upkeep. Four lines are live at once — 12.1, 13.3, 14.0 and 14.1 — and the recent tags are backports and CI fixes moving between them, authored by a small handful of maintainers. The last release with user-facing feature text is Citus 14.0 in February, which added PostgreSQL 18.1 support and pointed at a blog post rather than listing what changed.

What is Aim?

An experiment tracker grinding on storage performance — and quiet for over a year.

Aim is an open-source ML experiment tracker whose 3.2x line reads almost entirely as storage and indexing work: constant indexing of in-progress runs, reading from a single unified database, fallbacks when the index is missing, stalled-run detection. The user-facing additions in this window are narrow — a read-only UI mode, report creation, self-signed SSL support, PytorchLightning logger contexts. The most recent entry here is from May 2025, making this feed over a year stale.

Citus is in maintenance mode across four branches, with the feature work invisible from the feed.

◆ Current state

Citus is the Postgres extension that shards tables across a cluster, and its release feed right now is almost entirely branch upkeep. Four lines are live at once — 12.1, 13.3, 14.0 and 14.1 — and the recent tags are backports and CI fixes moving between them, authored by a small handful of maintainers. The last release with user-facing feature text is Citus 14.0 in February, which added PostgreSQL 18.1 support and pointed at a blog post rather than listing what changed.

◆ Where it's heading

The shape here is a mature extension keeping several supported branches alive rather than pushing new capability. Correctness is the live concern: the 12.1 patches fix wrong query results, an EXPLAIN segfault, a standby coordinator crash and a deadlock, all backported from work done on newer branches. Note that the release notes are thin by design — 13.3 and 14.1 list only PR titles for backports and test plumbing, so the feed understates whatever is landing on the main line.

◆ Prediction

More 12.1 patch tags are the safe expectation while that branch stays supported. Whether the 14.x line picks up new distributed-query features is not visible from these entries — the notes only cover backports, so the main-branch work would have to be read elsewhere.

An experiment tracker grinding on storage performance — and quiet for over a year.

◆ Current state

Aim is an open-source ML experiment tracker whose 3.2x line reads almost entirely as storage and indexing work: constant indexing of in-progress runs, reading from a single unified database, fallbacks when the index is missing, stalled-run detection. The user-facing additions in this window are narrow — a read-only UI mode, report creation, self-signed SSL support, PytorchLightning logger contexts. The most recent entry here is from May 2025, making this feed over a year stale.

◆ Where it's heading

The direction across these releases is toward making the local storage layer trustworthy at scale rather than expanding what the tracker does. Repeated fixes around index corruption, empty index.db handling, false-positive metric checks, and session refresh point at users hitting durability problems on long-running or high-volume tracking. Integration surface grows only where contributors push it — S3 client config, Lightning contexts, remote mass updates all arrive as outside contributions rather than a planned roadmap.

◆ Prediction

With no release visible in over a year, the honest read is that cadence has stopped rather than shifted; the entries give no signal of a 4.x line or a direction change. If work resumes, the pattern suggests more storage-correctness fixes before any new capability.
