Bump compiler banners and package version to 1.0.0, activate SEMVER policy, and add RELEASE_v1.0.0 notes. Fix closure auto-Drop leaking outer Array drops into nested capture bodies (iter_hof). Fmt-clean examples/src for CI.

# Bux v1.0.0 — Language Freeze
|
||
|
||
**Date:** 2026-07-27
|
||
**Tag:** `v1.0.0`
|
||
|
||
## What 1.0 means
|
||
|
||
- **Language freeze** for public surface: syntax, stdlib APIs, and CLI that
|
||
scripts depend on follow `docs/SEMVER.md`.
|
||
- **Normative spec:** `docs/LanguageRef.md`.
|
||
- **Compilers:** bootstrap (`buxc`, Nim) and selfhost (`buxc2`, Bux) both target
|
||
the same language for the shipped feature set.
|
||
- **Platform focus:** Linux primary; cloud/containers; cross/static/minimal
|
||
runtime. Windows is not a product platform.
|
||
|
||
## Shipped surface (summary)
|
||
|
||
| Area | Highlights |
|
||
|------|------------|
|
||
| Frontend | Pratt parser, recovery, macros (`macro!`, fragments, juxta/`tt`/`type`) |
|
||
| Types | Generics (mono), tuples, fat `func` ABI, algebraic enums |
|
||
| Ownership | `@[Checked]`, `@[Release]`, Drop/RAII, field-move + remaining Drop |
|
||
| Concurrency | M:N tasks, channels, async |
|
||
| Stdlib | Array/Map/Set/String/Iter HOF, Net/TLS, registry, Test |
|
||
| Tooling | `fmt`, `test`, `doc`, `check`, LSP (separate versioning), DWARF `#line` |
|
||
| Ecosystem | path/git/HTTP registry, lock + `--locked`, 4 apps, benches |
|
||
|
||
## Explicitly *not* 1.0 blockers
|
||
|
||
- True freestanding / bare-metal (`runtime_freestanding.c`, Cortex-M)
|
||
- Operators-only token paste; full `Array<int>` in `:type` fragments
|
||
- Windows product investment
|
||
- LLVM / non-C backends
|
||
|
||
## Upgrade notes from 0.5.x
|
||
|
||
No mandatory source migration for projects that already build on late 0.5.x.
|
||
New package scaffolds still default to package version `0.1.0` (package semver,
|
||
not language version).
|
||
|
||
### Fix included in 1.0.0
|
||
|
||
- **Closure Drop isolation:** lowering a nested closure no longer emits
|
||
outer-function `Array_Drop` / auto-Drop on the closure’s return path
|
||
(broke `iter_hof` and any capturing HOF over droppable locals).
|
||
|
||
## Verify
|
||
|
||
```bash
|
||
make build
|
||
./buxc --version # bux 1.0.0 (bootstrap)
|
||
make test # full gate
|
||
make selfhost # buxc2
|
||
# optional: make selfhost-loop
|
||
```
