Every release, newest first.

Hardening and tooling release. Requires Zig 0.16.0.

Added

• Command-authoring tools in the meta-CLI: zcli add option/arg/group/plugin and zcli mv/zcli rm restructure command files in place via an AST splice engine — no JSON blobs, no regeneration.
• zcli guide — version-matched, topic-based reference for the framework's idioms; zcli init scaffolds an AGENTS.md that points AI agents at it.
• zcli_secrets plugin — opt-in credential storage in the OS keychain (macOS Keychain, Linux Secret Service, Windows Credential Manager), no plaintext fallback.
• HTTP client with safe defaults over std.http.Client (credential headers stripped on cross-origin redirects), plus a canonical ghauth example showing the secrets + auth idiom.
• Arena-per-command allocator for execute(), and context.fail() for friendly, stack-trace-free command errors.
• Windows joins the first tier: unit tests and the full e2e suite (interactive tier via a ConPTY backend) run on Windows CI, upgrade self-replaces correctly on Windows, and the console is put into UTF-8 mode so multibyte I/O round-trips.

Fixed

• Two full-repo audit passes burned down 50+ findings: memory leaks in the parse pipeline, a PTY-harness deadlock, vterm out-of-bounds on resize, comptime build errors that now name the offending command, config command-scoping applied to TOML/YAML (was JSON-only), and legible errors instead of exit(1) throughout the build API.

Changed

• generate()/generateDocs()/addCommandTests() take typed configs and derive the zcli module themselves.
• The 2,460-line registry was split into focused submodules; zcli no longer re-exports all of serde.
• Releases are gated on the full test suite (including native Windows), and CI actions are pinned to SHAs.

The Zig 0.16 release — the largest since the project started. Breaking: requires Zig 0.16.0 (the new std.Io model).

Added

• zcli dev — watches your source and rebuilds on change, with restart-on-change for a running binary (native fs events via kqueue/inotify/FSEvents).
• zcli tree — prints the command hierarchy, sharing the framework's own discovery logic.
• Interactive wizard for zcli add command, plus declarative flags for scripted use.
• Interactive prompts (text, confirm, select, multi-select, password, search, number, editor), config file support for TOML and YAML with per-command scoping, and command aliases.
• Apps can name their generated Context type for full editor autocomplete in commands.
• End-to-end test suite for the meta-CLI; docs website; Windows console backend and a libc-free terminal stack (fully static musl builds on Linux).

Changed

• The monolithic interactive package was split into focused, standalone packages: zinput, terminal, vterm, zprogress, ztheme.
• vterm was removed from zcli's public re-exports — it's a testing tool, available directly.
• zcli.builtin(.help, .{}) shortcut for enabling built-in plugins.

Zig 0.15.1 era. Windows support landed (v0.15.0), std.posix.getenv was dropped for portability, repeated short options for array types were fixed, commands gained support for C dependencies and command-specific imports (v0.16.0), and a completions memory leak was fixed.

The foundation, built in ten days: build-time command discovery and routing, the plugin system (help, version, not-found, completions, config, output, upgrade), shell completions, hidden commands, shared modules, the zcli meta-CLI with init/release/upgrade, and the curl | sh install script. The dual-tag release scheme (v* library / zcli-v* CLI) was established at v0.11.0.
