v0.3.0

Added

• get-* query commands now return the value the SMU reports, shown in the CLI and in --json as a returned field; smu.query_mp1() / smu.query_rsmu() expose the raw read-back for library users
• --version flag, which prints the installed version and checks PyPI for a newer release; zenmaster.check_update() exposes the same check to library users
• Exception hierarchy for library users: ZenMasterError (base) with BackendUnavailable, SMUNotInitialized, UnsupportedCPU, all still subclass RuntimeError, so existing except RuntimeError keeps working
• smu.SmuStatus IntEnum for SMU status codes (SMU_OK etc. now alias it)
• ApplyResult TypedDict documenting the apply() result contract
• py.typed marker so downstream type-checkers use the bundled type hints
• PM-table support for the Raven/Picasso-era APUs (RavenRidge, Picasso, Dali, Pollock), which use a distinct table opcode set
• Linux can now read the PM table over PCI direct access (via /dev/mem) when ryzen_smu is not loaded

Changed

• tdc-limit and edc-limit now have descriptions and appear under "VRM & Currents" in --help instead of "Unknown command"
• Moved the MP1/RSMU mailbox tables, SMU status codes, and PM-table metadata into shared modules (mailbox.py, pmtable.py)
• Unified the Linux register send/poll path into one routine shared by the ryzen_smu and PCI backends; simplified apply() token parsing
• Removed unused runner helpers (get_socket_short, has_smu_support, get_commands)

Fixed

• Windows --table / --dump-table now work on VanGogh (Steam Deck) and Mendocino, which were missing from the PM-table family list
