- Filter `max` and `ultra` reasoning effort levels for Codex client versions prior to `0.144.0`.
- Extract and forward the `client_version` query parameter across model catalog response handlers.
- Add dotted version parsing and comparison utilities to verify extended reasoning level compatibility.
Closes: #5262
- Add registry generation tracking and a Codex catalog revision accessor to provide stable cache keys.
- Cache parsed model templates and rendered spawn-agent markdown, and reuse them across requests when revision/generation are unchanged.
- Invalidate/recompute caches when model registrations or catalog content change, and separate rewrite handling for spawn tool descriptions vs. message encryption stripping.
Closes: #4967
- Added `grok-imagine-image-2.0` as a first-class xAI image base model across validation, canonicalization, and routing checks.
- Registered the model in built-in model definitions so it appears in model metadata.
- Updated image model allowlists and request validation error messaging to include the new model.
- Marked the new model as hidden in client visibility override handling.
- Generalize spawn_agent tool path discovery into codexToolPathsByNames
driven by a name set, and add codexCollaborationMessageTools covering
spawn_agent, send_message, and followup_task.
- Strip parameters.properties.message.encrypted from all collaboration
message tools (top-level tools and input[].additional_tools, including
nested namespace tools) via removeCodexCollaborationMessageEncryption,
invoked unconditionally before the spawn-agent optimization decision.
- Extend optimize_multi_agent_v2_test.go with coverage for the new tool
path discovery, encrypted-field removal semantics, preservation of
unrelated encrypted fields, and end-to-end OptimizeCodexMultiAgentV2Request
behavior across namespace and additional_tools payloads.

- Add optional `max-context-length` model configuration across supported provider model types and expose it via `GetMaxContextLength`.
- Propagate the override into model metadata so Codex/client model catalog responses honor the configured value (`context_window`, `max_context_window`, and `max_context_length`).
- Update example configuration with documented usage of the new option.
Closes: #4728
- Introduced a new reasoning level, `minimal`, to the `codexClientAllowedReasoningLevels` map.
- Updated response-building logic to include descriptive messaging for the `minimal` level.
Closes: #4542
- Implemented logging for Codex remote media forwarding start events, including detailed connection and credential metadata.
- Added `formatLogFieldValue` for quoting specific log fields and ensured newline safety in log output.
- Enhanced unit tests to validate log content, escaping, and field inclusion.
- Implemented a TCP proxy for WebRTC candidate tunneling in Codex Live, supporting passive TCP candidates on port 443.
- Restricted tunneling to globally routable public IPs and added safeguards for rejecting unsafe/private targets.
- Added robust validation of STUN BindingRequest frames before forwarding to upstream candidates.
- Includes extensive unit tests for proxying behavior, candidate validation, and tunnel edge cases.
- Added comprehensive diffing for Codex live media relay settings, including support for public IP, UDP port ranges, and ICE server changes.
- Introduced `displayOptionalValue` utility to handle optional values in diff outputs.
- Improved test coverage for config change detection, ensuring no sensitive information leakage.
- Replaced `allow-private-remote-ips` with the new `disable-private-remote-ips` property, adding YAML backward compatibility.
- Updated Codex live handler to differentiate media relay configuration changes and runtime updates.
- Introduced a new `models` package for organizing Codex client model templates and building responses.
- Migrated Codex response handling to `codexmodels.BuildResponse`.
- Added comprehensive tests for model metadata, reasoning levels, and input modalities handling.
- Updated Kimi and Gemini executors to use `TranslateRequestWithCodexMultiAgentV2` for improved multi-agent v2 optimization.
- Enhanced configuration and API server to support `CodexOptimizeMultiAgentV2`.
- Added codex multi-agent V2 optimizations in `config`, `executor`, and `watcher` modules.
