PyPI: https://pypi.org/project/mcp-portainer/2.42.0/

Targets Portainer 2.42.x.

Added

Maintainer release skill at .claude/skills/portainer-mcp-release/. Project-local Claude Code skill that walks through spec-bump releases (Portainer minor → MCP minor): finding the upstream patch target, spec regeneration, op/tag delta recounting, orphan inventory refresh, pin bumps across distribution docs, CHANGELOG promotion, commit, push, merge, tag. Bundles a spec_deltas.py script that prints the new per-profile coverage and orphan table paste-ready for docs/profiles.md.

Changed

Embedded spec bumped to Portainer EE 2.42.0 (was 2.41.1). Default BASE,DOCKER,KUBERNETES profile coverage grows from ~180 to ~197 operations; the five-profile union grows from ~306 to ~342. Upstream removed the intel tag (6 operations); dropped from the orphan tag list in docs/profiles.md.
Bump actions/checkout to v6.0.2 and astral-sh/setup-uv to v8.1.0 in the CI and release workflows. Clears the Node.js 20 deprecation warning ahead of the forced Node.js 24 default on 2026-06-02.
