GravityKit
GravityKit ships weekly across a whole plugin suite, with an MCP server now part of the lineup.
A side-by-side editorial comparison of GoCD and Heroku — release velocity, themes, recent moves, and the top alternatives to consider.
GoCD's changelog is one maintainer keeping a 2010s CI server running on current runtimes.
The visible work is almost entirely platform upkeep, and nearly all of it is authored by a single contributor. The baseline has been walked forward repeatedly — Java 17 minimum, then building and packaging on Java 21, then Java 21 as the hard minimum with macOS x64 support dropped — while container images moved from Alpine and CentOS Stream to Wolfi and Chainguard, Rails went from 6.1 through 7.1, and Hamcrest was replaced by AssertJ across the test suite. 26.1.0 is the exception in substance: it carries security fixes described as affecting all prior GoCD versions, with an explicit recommendation to upgrade as soon as possible.
Runtime bumps fill the changelog; the managed Postgres line is where Heroku actually moves.
Day to day, Heroku's changelog is language-runtime upkeep: Python, Node, Ruby, Go, PHP, JRuby and .NET point releases, buildpack refreshes for Pipenv and uv, and periodic rebuilds of the Heroku-22, Heroku-24 and Heroku-26 stacks now maintained in parallel. The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.

This is a mature product in custodial maintenance rather than development. The pattern across releases is dependency deduplication, dead code removal, deprecation cleanup and base image swaps — the work that keeps a large Rails and Java codebase installable and patchable on current operating systems. Feature entries are rare enough that their absence, rather than any particular change, is the signal.
Given the security advisory in 26.1.0 covers all earlier versions and the release notes point offsite for detail, the practical next step for operators is that upgrade. The entries show no queued feature work to project from.

The exception is the managed database. Postgres 18 entered beta on 14 July and reached general availability on 4 August, and Heroku deprecated Postgres 15 on the same day.
The platform is running two clocks at once. One is a near-daily maintenance cadence that keeps supported runtimes current and rarely changes behaviour. The other is a deliberate, publicly staged lifecycle for the data services, where a major version is walked from beta to GA and the version three releases behind is retired in the same announcement. Kafka is on the same track, with 2.8 and 3.7 deprecations and a revised version-support policy posted in late July.
Given that Postgres 15's deprecation was announced alongside 18's general availability, the next concrete step is a published end-of-life date and forced-upgrade window for Postgres 15. The runtime bumps will continue at their current weekly rhythm.

They serve adjacent needs but don't currently overlap on shipped themes. GoCD and Heroku are shipping at a similar cadence (velocity 5.0 vs 5.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. GoCD and Heroku are shipping at a similar cadence (velocity 5.0 vs 5.0, both within Sparkpulse's "active" band).
