Prometheus vs uproot5
A side-by-side editorial comparison of Prometheus and uproot5 — release velocity, themes, recent moves, and the top alternatives to consider.
Prometheus vs uproot5: at a glance
What is Prometheus?
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.
What is uproot5?
Uproot quietly made RNTuple the default write format — filed under 'chore'.
Uproot ships small, frequent 5.7.x releases in which the RNTuple work dominates and is often buried below the feature list. Since switching the default write format to RNTuple in 5.7.0, the releases have been about making that path complete: entry bounds and report=True for RNTuple.iterate, GPU interpretation of RNTuple data with nvCOMP decompression, support for the v1.0.1.0 format, and the library kwarg finished. Two of the six releases in this window list no new features at all.

Prometheus
5.0DEVOPS
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
◆ Current state
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.
◆ Where it's heading
PromQL is the centre of gravity. Features enter behind promql-experimental-functions or a dedicated flag, get renamed once while experimental (min/max to min_of/max_of), then graduate — first_over_time and duration expressions are the current graduates, start_timestamp the next candidate behind use-start-timestamps. The API is simultaneously being tightened, with the stats parameter deprecated ahead of rejection in the next major and credential forwarding across redirects already removed in 3.13. Service discovery keeps absorbing clouds as their APIs change, OCI added and a Hetzner label dropped in the same release.
◆ Prediction
A 3.14.0 final should follow the release candidate within weeks, carrying the duration-expression and first_over_time promotions with it.
uproot5
0.0DEVOPS
Uproot quietly made RNTuple the default write format — filed under 'chore'.
◆ Current state
Uproot ships small, frequent 5.7.x releases in which the RNTuple work dominates and is often buried below the feature list. Since switching the default write format to RNTuple in 5.7.0, the releases have been about making that path complete: entry bounds and report=True for RNTuple.iterate, GPU interpretation of RNTuple data with nvCOMP decompression, support for the v1.0.1.0 format, and the library kwarg finished. Two of the six releases in this window list no new features at all.
◆ Where it's heading
This is a migration project wearing patch-release clothing. The direction is that RNTuple, ROOT's newer columnar format, becomes what Uproot writes and reads by default, with the older TTree path maintained rather than developed. The GPU decompression work points further out: reading physics data straight into accelerator memory rather than staging it through the CPU. Expect the remaining gaps to keep surfacing as bug fixes in the RNTuple path as more of the field writes in the new format.
◆ Prediction
Continued 5.7.x patches closing RNTuple feature parity with TTree, with the GPU and nvCOMP path the most likely area to gain rather than just get fixed.
