February 2026 Monthly Summary for open-source codex projects across two repositories. Focused on delivering user-visible upgrade capabilities, tightening command-control workflows, improving model identification reliability, and enhancing routing/notification observability. This work drove better upgrade visibility, reduced operational risk, and increased system-wide observability to support faster decision-making and safer operations. Key developments: - Added upgrade metadata to model listings and modelList responses to surface recommended upgrades for each model, enabling a proactive upgrade experience in the UI. - Implemented granular exec command approvals at the request level to tighten control over critical operations and reduce risk of unauthorized actions. - Improved model identification reliability by relying on the model value from the response header, eliminating false positives in slug naming across events. - Introduced a new model/rerouted notification type to surface routing changes due to high-risk activity, improving observability and incident response. - Extended model listing responses to include upgrade information in server listings, increasing visibility into upgrade opportunities and facilitating user-driven upgrade decisions.

January 2026 monthly summary for zed-industries/codex: Key feature deliveries across the repository focused on configuration exposure, server lifecycle reliability, and enhanced user prompts. These changes enable safer defaults, easier extensibility, and improved UX for approvals and planning. No dedicated bug-fix tickets were logged this month; the work primarily comprised feature delivery and reliability improvements that reduce manual steps and maintenance overhead.

December 2025 summary for zed-industries/codex: Delivered MCP integration improvements, hardened code signing, and non-blocking async improvements to boost reliability, security, and performance. Key features include MCP integration in App Server with server listing and in-session OAuth login, disk-backed MCP status refresh, and non-blocking API paths. Implemented Linux Sigstore signing and Windows Azure trusted signing, plus Mac code-sign flow refactor for parity. API and code hygiene improvements include renaming listMcpServers to listMcpServerStatus, making listMcpServerStatus and app_server.list_models non-blocking, and removing rmcp feature flags. Addressed stability issues by disabling trusted signing package cache hits and stabilizing Windows signing through a rollback and re-application as part of the release process. These changes reduce risk in distribution, improve user experience in MCP onboarding, and accelerate developer efficiency by enabling real-time status fetches and non-blocking operations.
