What is Apache TomEE?

A Jakarta EE server whose changelog is mostly dependabot — until EE11 moved to main

TomEE ships a steady stream of 10.1.x and 10.2.0 patch releases whose release notes are dominated by dependency bumps and regenerated BOMs, with one or two real TOMEE- ticket fixes buried in each. The genuinely new thing is 11.0.0-M1, the first milestone of the next major line, created when Jakarta EE 11 work moved onto the main branch. The 10.x line continues in parallel as the stable target.

What is Prometheus?

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

Apache TomEE vs Prometheus: editorial side-by-side

A2.5

A Jakarta EE server whose changelog is mostly dependabot — until EE11 moved to main

◆ Current state

TomEE ships a steady stream of 10.1.x and 10.2.0 patch releases whose release notes are dominated by dependency bumps and regenerated BOMs, with one or two real TOMEE- ticket fixes buried in each. The genuinely new thing is 11.0.0-M1, the first milestone of the next major line, created when Jakarta EE 11 work moved onto the main branch. The 10.x line continues in parallel as the stable target.

◆ Where it's heading

The project is running the classic app-server two-track pattern: keep 10.x boring and current on its dependency surface, while the EE11 rearchitecture accumulates on main behind milestone tags. Nearly all visible energy goes into staying aligned with Tomcat, ActiveMQ, Hibernate, Jackson and MicroProfile versions — which for a server whose value is spec compliance is the actual product work, not a distraction from it.

◆ Prediction

Expect further 11.0.0 milestones with EE11 certification as the gate, while 10.1.x/10.2.x continue absorbing upstream dependency updates and isolated ticket fixes.

Prometheus logo5.0

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default

◆ Current state

3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

◆ Where it's heading

The project is spending its feature budget on start timestamps, appearing across PromQL, TSDB encoding, and remote write V2 in the same release but held behind use-start-timestamps and histograms-st-encoding. Everything else follows the established rhythm of promoting one experimental function per cycle and adding a cloud discovery source. The API deprecations are being staged carefully, warning now and rejecting at the next major.

◆ Prediction

Start timestamps are the obvious candidate to lose their feature flags once the encoding and remote-write halves have run together, and the stats parameter values now warned on will be rejected in the next major.
