Changelog

All notable changes to this project are documented here. Dates use the ISO format (YYYY-MM-DD).

[3.2.0] - 2025-11-14

Added

• GPT 5.1 model family support: normalization for gpt-5.1, gpt-5.1-codex, and gpt-5.1-codex-mini plus new GPT 5.1-only presets in the canonical config/full-opencode.json.
• Documentation updates (README, docs, AGENTS) describing the 5.1 families, their reasoning defaults, and how they map to ChatGPT slugs and token limits.

Changed

• Model normalization docs and tests now explicitly cover both 5.0 and 5.1 Codex/general families and the two Codex Mini tiers.
• The legacy GPT 5.0 full configuration is now published as config/full-opencode-gpt5.json; new installs should prefer the 5.1 presets.

[3.1.0] - 2025-11-11

Added

• Codex Mini support end-to-end: normalization to the codex-mini-latest slug, proper reasoning defaults, and two new presets (gpt-5-codex-mini-medium / gpt-5-codex-mini-high).
• Documentation & configuration updates describing the Codex Mini tier (200k input / 100k output tokens) plus refreshed totals (11 presets, 160+ unit tests).

Fixed

• Prevented Codex Mini from inheriting the lightweight (minimal) reasoning profile used by gpt-5-mini/nano, ensuring the API always receives supported effort levels.

[3.0.0] - 2025-11-04

Added

• Codex-style usage-limit messaging that mirrors the 5-hour and weekly windows reported by the Codex CLI.
• Documentation guidance noting that OpenCode's context auto-compaction and usage sidebar require the canonical config/full-opencode.json.

Changed

• Prompt caching now relies solely on the host-supplied prompt_cache_key; conversation/session headers are forwarded only when OpenCode provides one.
• CODEX_MODE bridge prompt refreshed to the newest Codex CLI release so tool awareness stays in sync.

Fixed

• Clarified README, docs, and configuration references so the canonical config matches shipped behaviour.
• Pinned hono (4.10.4) and vite (7.1.12) to resolve upstream security advisories.

[2.1.2] - 2025-10-12

Added

• Comprehensive compliance documentation (ToS guidance, security, privacy) and a full user/developer doc set.

Fixed

• Per-model configuration lookup, stateless multi-turn conversations, case-insensitive model normalization, and GitHub instruction caching.

[2.1.1] - 2025-10-04

Fixed

• README cache-clearing snippet now runs in a subshell from the home directory to avoid path issues while removing cached plugin files.

[2.1.0] - 2025-10-04

Added

• Enhanced CODEX_MODE bridge prompt with Task tool and MCP awareness plus ETag-backed verification of OpenCode system prompts.

Changed

• Request transformation made async to support prompt verification caching; AGENTS.md renamed to provide cross-agent guidance.

[2.0.0] - 2025-10-03

Added

• Full TypeScript rewrite with strict typing, 123 automated tests, and nine pre-configured model variants matching the Codex CLI.
• CODEX_MODE introduced (enabled by default) with a lightweight bridge prompt and configurability via config file or CODEX_MODE env var.

Changed

• Library reorganized into semantic folders (auth, prompts, request, etc.) and OAuth flow polished with the new success page.

[1.0.3] - 2025-10-02

Changed

• Major internal refactor splitting the runtime into focused modules (logger, request/response handlers) and removing legacy debug output.

[1.0.2] - 2025-10-02

Added

• ETag-based GitHub caching for Codex instructions and release-tag tracking for more stable prompt updates.

Fixed

• Default model fallback, text verbosity initialization, and standardized error logging prefixes.

[1.0.1] - 2025-10-01

Added

• README clarifications: opencode auto-installs plugins, config locations, and streamlined quick-start instructions.

[1.0.0] - 2025-10-01

Added

• Initial production release with ChatGPT Plus/Pro OAuth support, tool remapping, auto-updating Codex instructions, and zero runtime dependencies.
