What is Coolify?

Coolify is in a sustained security-hardening run while the v4 beta inches forward.

Coolify is releasing roughly weekly beta builds dominated by security and reliability work: mass-assignment protection, query scoping, input validation, encrypted webhook secrets, accidental-prune protection. Each release also slips in small bug fixes and the occasional new service template. The same release is published across two feeds, so duplicates are common in the changelog.

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.

Coolify is in a sustained security-hardening run while the v4 beta inches forward.

◆ Current state

Coolify is releasing roughly weekly beta builds dominated by security and reliability work: mass-assignment protection, query scoping, input validation, encrypted webhook secrets, accidental-prune protection. Each release also slips in small bug fixes and the occasional new service template. The same release is published across two feeds, so duplicates are common in the changelog.

◆ Where it's heading

The product is hardening for production self-hosted use rather than expanding feature surface. Several recent fixes — team-scoped queries, locked properties, encryption for secrets — are the kind of multi-tenant defenses that matter when self-hosted PaaS instances start hosting more than one team's workloads. The v4 beta is converging toward stable, but security debt is still being paid down before that happens.

◆ Prediction

Expect a v4 GA cut once the security backlog drains and the new-template flow stabilizes, plus an explicit audit/security advisory listing the hardening work. New service templates will continue to drip in opportunistically.

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.
