v0.5.0

Added

• macOS backend (AMD Hackintosh): CPU detection via sysctl, and SMU access through DirectHW.kext, with a kext-free fallback over IOPCIBridge (tuning only, no PM table)
• CLI --iopci (macOS only) forces the IOPCIBridge path instead of DirectHW
• zenmaster.hardware.detect() reads machdep.cpu.family / machdep.cpu.model / machdep.cpu.brand_string on macOS instead of /proc/cpuinfo

Changed

• --info (text and --json) omits the Backend/Driver fields entirely when the SMU hasn't been initialized, instead of printing "not initialized"
• --table, --dump-table, and --sensors point to DirectHW.kext specifically when they fail on the IOPCIBridge path, instead of a generic "not available" message

v0.4.0

Added

• CLI --sensors (and --sensors --json): compact live readout of temp, load, socket power, iGPU clock/temp, and memory clock
• CLI --info now shows a Driver line with the driver name, version, and status (or PCI direct access); same data under --info --json
• smu.read_pm_sensors(family) reads and decodes the PM table in one call, returning a PmSensors (or None). table.read_sensors(data, ver) decodes raw bytes you already have
• smu.module_status() returns one ModuleStatus verdict for the driver (ok, version, min_version, reason). Helpers: module_version(), module_version_ok(), is_available(), secure_boot_enabled(), driver_name()
• smu.ensure_backend(): like init() but returns the backend or None instead of raising
• smu.unavailable_reason(): the message explaining why the SMU can't be used, or None when it can
• smu.send_arg(family, name, value) sends one value to every mailbox the arg maps to, returning [(mailbox, opcode, status), ...]
• resolve(name, cpu_family, cpu_model) builds a CpuInfo from explicit values without reading /proc/cpuinfo
• runner.is_supported(family)
• All of the above are re-exported at the top level, so apps don't import from zenmaster.linux

Changed

• Linux now checks the ryzen_smu version (drv_version) and requires >= 0.1.7, with the installed version in the error
• Backend selection follows Secure Boot: off uses PCI direct access, on uses ryzen_smu. A loaded module is no longer preferred over PCI when Secure Boot is off
• On Windows, the driver is PawnIO with no version requirement, and Secure Boot does not apply

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

v0.2.0

Added

• Public library API: from zenmaster import detect, apply, runner, smu, CpuInfo
• runner.is_flag_arg() to query args that take no value
• vrmcvip-current (VanGogh) for full RyzenAdj arg parity

Changed

• Linux PCI backend now probes writability with a 0x47 register round-trip
  (like UXTU4Linux) instead of only checking that the config file exists, so a
  non-writable bus (no root, lockdown) fails at init with a clear message
• Unified project description to "Adjust power management settings for Ryzen
  CPUs on Linux and Windows"
• Rewrote README with a fuller overview, compatibility table, and an accurate
  RyzenAdj comparison
• Args that require a value now report an error (or show help on the CLI)
  when passed without =value, instead of silently sending 0
• apply() results always include a consistent set of keys (error is
  None on success), making the return shape stable for consumers
• Argument names are normalised to lowercase/hyphen form in apply() results
• Modernised packaging to PEP 639 SPDX license metadata

Fixed

• Windows PM table read now aborts if the final table-transfer retry is still
  rejected, instead of reading stale/garbage physical memory
• Windows SMU polling sleeps briefly after a fast initial spin, avoiding a busy
  loop that pinned a core while waiting for the mailbox
• --skin-temp-limit (a power limit in mW) is no longer multiplied by 256;
  only the temperature args apu-skin-temp and dgpu-skin-temp are scaled,
  matching RyzenAdj
• Negative values (e.g. Curve Optimiser --set-coall=-20) now wrap to
  unsigned 32-bit like RyzenAdj, instead of being clamped to 0
• Flag args (--max-performance, --enable-oc, …) always send 0, ignoring any
  value passed, matching RyzenAdj's boolean handling
• smu.send_* now raise a clear error if called before smu.init()
• smu.init() is idempotent and no longer leaks the Windows PawnIO handle
• CLI shows help for a malformed argument before requiring root
• apply() handles malformed preset strings (unclosed quotes) gracefully
• --table no longer shows duplicate TDC values in EDC rows on Zen 5 tables

v0.1.1

Fixed

• Workflow and packaging fixes for initial PyPI release
