v0.6.0

First PyPI release under the name mcp-sequential-thinking. Install with uvx mcp-sequential-thinking or pip install mcp-sequential-thinking.

Highlights

• Thought revisions & branching: process_thought accepts is_revision, revises_thought_number, branch_from_thought and branch_id to revise earlier thoughts or fork alternative reasoning paths, with cross-field validation, revision-aware analysis output and branch/revision statistics in generate_summary.
• Append-only JSONL session format (schema v2): O(1) appends per thought, crash recovery for interrupted writes, and automatic lossless migration of v0.5.x current_session.json files on first start.
• Import/export hardening: imports can no longer silently wipe the session (missing thoughts key, nonexistent file); exports are confined to an exports/ subdirectory and can't clobber the session file; path errors no longer leak the storage location.
• CI & release automation: Linux/Windows × Python 3.10/3.12 test matrix, Dependabot, security policy, and PyPI Trusted Publishing.

Breaking changes

• Relative export/import paths now resolve under ~/.mcp_sequential_thinking/exports/.
• Session file format is now JSONL (current_session.jsonl); migration from v1 is automatic.
• PyPI package name is mcp-sequential-thinking (previously unpublished as sequential-thinking).
