-   [#1523](https://github.com/eyaltoledano/claude-task-master/pull/1523) [`fc1a79f`](https://github.com/eyaltoledano/claude-task-master/commit/fc1a79f2565b0d8c24f009aec2c473a335262ae2) Thanks [@Crunchyman-ralph](https://github.com/Crunchyman-ralph)! - Codex cli Validate reasoning effort against model capabilities
    -   Add provider-level reasoning effort validation for OpenAI models
    -   Automatically cap unsupported effort levels (e.g., 'xhigh' on gpt-5.1 and gpt-5 becomes 'high')

-   [#1549](https://github.com/eyaltoledano/claude-task-master/pull/1549) [`98087ac`](https://github.com/eyaltoledano/claude-task-master/commit/98087acae91fad7345bdb4c253d4dfd0d584f81e) Thanks [@Crunchyman-ralph](https://github.com/Crunchyman-ralph)! - Improve CLI startup speed by 2x

-   [#1545](https://github.com/eyaltoledano/claude-task-master/pull/1545) [`a0007a3`](https://github.com/eyaltoledano/claude-task-master/commit/a0007a3575305c367c8561584aa0dbd181f5e1cc) Thanks [@Crunchyman-ralph](https://github.com/Crunchyman-ralph)! - Smarter project root detection with boundary markers
    -   Prevents Task Master from incorrectly detecting `.taskmaster` folders in your home directory when working inside a different project
    -   Now stops at project boundaries (`.git`, `package.json`, lock files) instead of searching all the way up to the filesystem root
    -   Adds support for monorepo markers (`lerna.json`, `nx.json`, `turbo.json`) and additional lock files (`bun.lockb`, `deno.lock`)
