GoKawiilGforth 1.0 released with new stability guarantees for word set
The Gforth Forth system has reached version 1.0, introducing formal 'Stability Goals' documentation that specifies which words are guaranteed for long-term support versus those that may be deprecated. The release also adds several previously undocumented features while continuing to leave Gforth EC (Embedded Controller) development paused since version 0.7, with users still directed to that earlier version for embedded work.
GoKawiil's interpretation of the reporting above, not reported fact.
Formalizing a stability policy suggests the Gforth project is maturing toward a more predictable API for developers building long-lived Forth applications, reducing the risk of breaking changes in future releases. The continued stall on Gforth EC indicates embedded-systems users may need to rely on older tooling, which could affect projects targeting microcontrollers via Forth.
- Gforth 1.0 formally documents which words are stable versus deprecated, via new 'Stability Goals' guidance.
- Several features already present in earlier builds are now documented for the first time in this release.
- Gforth EC (embedded controller variant) has seen no development since version 0.7, and users are advised to keep using that older release.
