Full notes

- Commit message generation and tasks with reasoning off no longer fail with a 400 error on GPT-6 Astra, GPT-6.1 Sol, Claude Fable 5 or Claude Opus 5.5
- Cline no longer exits about 3 seconds after an MCP server or hook quits before reading all of its input
- Settings migrated from the VS Code extension no longer add an empty SAP AI Core provider
- `cline mcp add` keeps your `--header` values when it opens the setup wizard. Before, accepting the prefilled answers saved a remote server without its headers (for example, `Authorization`). The wizard now asks for one header per prompt and validates each one the same way as `--yes`
- `cline dashboard` is now `cline hub dashboard`. The old command still works as a hidden alias
- A bare `cline hub` prints its subcommands
- `cline doctor log` opens the file set by `CLINE_LOG_PATH` when that variable is set
- `cline --help` is corrected: `--retries` shows its real default of 3 (it said 6), and `--thinking` explains that it falls back to the level picked in `/model`
- A bare `--retries` with no count is now rejected with an error instead of crashing
- Options that were accepted but never did anything are removed and now fail with "unknown option": `cline history --page`, and `cline schedule create`/`update` `--autonomous`, `--no-autonomous`, `--idle-timeout`, `--poll-interval` and `--delivery-channel`. Remove them from scripts. Existing schedules saved with them still load
- `cline schedule create`, `update` and `import` reject a delivery that could never be posted, such as `--delivery-adapter` without `--delivery-thread` or an adapter that isn't a known connector. Before, the schedule was saved and its results were silently never posted. Errors name the flag or `--metadata-json` path to fix
- Refreshed the model catalog. Adds Claude Haiku 5.5. Default models change for Google Vertex AI (Claude Sonnet 5.5 → Claude Haiku 5.5), Cortecs, DevPass (LLM Gateway), Eden AI, GitHub Copilot, LLM Gateway, NanoGPT, OpenCode Go, Requesty, and Vivgrid (most now Claude Haiku 5.5)
