ccc 0.4.2

ccc 0.4.2

• Added post-run version update detection in Python and Rust: after a coding-CLI run, ccc may warn on stderr when a newer version is available (crates.io + GitHub releases, cached under ~/.cache/ccc/update-check.json). New [update] config keys check, auto_update, and interval_hours, plus env overrides CCC_UPDATE_CHECK, CCC_AUTO_UPDATE, CCC_UPDATE_CACHE, and CCC_UPDATE_INTERVAL_HOURS. Optional auto_update starts a background cargo install ccc --force for cargo-installed binaries.
• Extended the thinking ladder to +0..+5 in Python and Rust and added support for all OpenAI gpt-5.6 reasoning-effort tiers (none/low/medium/high/xhigh/max, excluding the ultra run mode). +xhigh now maps to level 4 and +max to level 5 (previously both were level 4); +5 is a new token. The codex runner maps each level to codex exec -c model_reasoning_effort=<value> and defaults to medium via a new per-runner default; runners with fewer tiers clamp +5 down to their top tier (e.g. claude +5 → max, pi +5 → xhigh). Behavior change: codex now always emits a reasoning-effort override (previously none), defaulting to medium.

ccc 0.4.0

ccc 0.4.0

• Fix Pi aliases with configured providers so ccc passes Pi's explicit --provider flag alongside --model.
• Fix Rust Client planning so pi command specs are classified as RunnerKind::Pi, enabling CCC_REAL_PI and library binary overrides.
• Add Python/Rust resolver, Rust Client, and cross-implementation CLI regression coverage for @pi-mimo25p.

ccc v0.3.0

What's Changed

New Features

• --timeout-secs - Add watchdog timeout control that kills the wrapped runner after N seconds, prints a stderr warning, and exits with status 124. Available to both CLI and library callers via CommandSpec::with_timeout_secs.

• Pass-through output modes - Four new modes pass raw output without JSON parsing or formatting:

  • pass-text (.pt) - raw stdout/stderr, non-streaming
  • stream-pass-text (..pt) - raw output while runner is working
  • pass-json (.pj) - raw structured output, non-streaming
  • stream-pass-json (..pj) - raw structured output while runner is working

JSON Event Handling

• OpenCode reasoning normalization - OpenCode type:"reasoning" events are now parsed into the shared thinking event path, with sessionID captured even when it arrives before step_start.

• Claude Code event coverage expanded - Added 11 new system subtypes, 7 new top-level message types, new delta/content block types, and new error subtypes. Previously-unhandled events now properly handled.

Other Changes

• 8345681b - add failover to tasks

v0.2.0

0.2.0 - 2026-04-17

• Added a typed Rust invocation API around Client, Request, Plan, Run, and typed transcript/output models, plus a compatibility sugar parser for ccc-style tokens.
• Changed the Rust CLI to plan and execute through the new library path instead of wiring directly through parser internals, while keeping top-level help, version, config, config --edit, and add flows CLI-owned.
• Improved the published Rust crate surface with stronger docs.rs metadata, crate-level API documentation, and clearer library examples for both typed requests and direct runner execution.

ccc 0.1.2

What's changed

This release supersedes v0.1.1. v0.1.1 was published successfully to crates.io, but the first GitHub binary workflow exposed a Windows-only Rust compile issue in the release build.

• Fixed Windows Rust builds by constructing ExitStatus with platform-specific raw status values.
• Kept the 0.1.1 user-facing changes: ccc help, unknown JSON artifact retention, formatted Codex error rendering, run artifacts, config editing, version reporting, Gemini/Cursor support, and the polished Rust crate README.
• GitHub release binaries are built by the release workflow for Linux, macOS, and Windows.

Install

cargo install ccc

Verification

• cargo check --manifest-path rust/Cargo.toml --target x86_64-pc-windows-gnu
• cargo package --manifest-path rust/Cargo.toml
• cargo publish --manifest-path rust/Cargo.toml --dry-run
• ./test_impl.sh python
• ./test_impl.sh rust
• env RUSTUP_TOOLCHAIN=stable PYTHONPATH=. python3 tests/test_harness.py Rust -v

ccc 0.1.1

Superseded by v0.1.2

v0.1.1 was published successfully to crates.io, but the first GitHub binary workflow exposed a Windows-only Rust compile issue in the release build.

Use v0.1.2 instead:

cargo install ccc

The v0.1.2 release includes the same user-facing changes plus the Windows release-build fix.
