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.

What is SimpleSAMLphp?

Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.

SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

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.

S5.0

Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.

◆ Current state

SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

◆ Where it's heading

This is pure maintenance cadence, not product development. The pattern across the last ten releases is consistent: security issues get simultaneous twin tags on both supported branches, everything else lands as branch-local bugfix points. The only release in the window that documented its own content was v2.4.6/v2.5.1 in May, which listed three GHSA advisories.

◆ Prediction

Expect the next tags to continue the twin-branch pattern — a paired 2.4.x and 2.5.x whenever an advisory lands, with content again deferred to the external changelog.
