Previous Releases

805.0.0-alpha.1 (current public alpha)

First public compiler alpha. GitHub Release tag v805.0.0-alpha.1. MAJOR 805 means the emit ceiling is PHP 8.5 (the compiler still targets 8.2–8.4 via output.phpVersion). Runtime packages version independently as 80N.X.Y (source 0.0802.0.0805.0.0).

This is a prerelease. Semver compatibility guarantees apply from the first stable 805.0.0, not from alpha. See Roadmap and Release Planning.

Release History

| Version | Notes |
|---------|--------|
| 805.0.0-alpha.1 | Public alpha. Tier 1 (stories 01–16.5) plus generic type-parameter defaults. LSP, sourcemaps, Xdebug proxy, and generate_tyhpdef are not included. |

Note

Compiler MAJOR encodes the highest supported PHP version (805 = PHP 8.5 and below). Tyhp syntax removal happens on MINOR. Runtime Composer packages do not use the compiler version string. See Release Planning.
