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.
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 0.0 → 802.0.0–805.0.0).
This is a prerelease. Semver compatibility guarantees apply from the first stable 805.0.0, not from alpha. See Roadmap and Release Planning.
