Changelog
PsyCloud is in early alpha. The authoritative, always-current record of changes is
CHANGELOG.md in the repository,
which follows Keep a Changelog and
Semantic Versioning. This page summarizes the highlights; consult the repo
file for the complete list.
The core library is published as 0.0.1. The 1.0.0 heading in the changelog tracks the
in-progress modernization milestone (the full TypeScript rewrite) rather than a dated public
release. Treat APIs as subject to change and pin to a specific commit if you need stability.

the DSL fits the current canonical pipeline.
