Version Support

Frankenstack tracks the two most recent PHP major versions. Each supported version has a dedicated branch and a corresponding image tag (e.g., 8.4, 8.5). As new PHP versions are released, we update these tags in place—so pulling ghcr.io/adiachenko/frankenstack:8.5 always gets you the latest build for that major version.

When a PHP version reaches end-of-life or falls out of our support window, its tag is frozen and remains available for historical use, but receives no further updates. This keeps the tagging scheme simple while ensuring you can always pin to a specific major version without surprises.

Immutable date tags

Each update to a version tag also publishes a date-stamped tag, e.g. ghcr.io/adiachenko/frankenstack:8.5-20260610.32. Unlike the version tags above, these are never updated after publishing, so you can pin a known-good build in production instead of tracking a moving tag.
