## [Unreleased]

## [0.5.0] - 2026-10-17

### Added
- `get_licenses` (napalm-device-types `LicenseMixin`, 4.15) on `redfish` and `bmc`: the
  licenses the BMC asks for, as facts (NetOrk/netork#1111). A BMC that refuses Redfish
  altogether reports each license it names as `missing`, with its message. One that answers
  but withholds parts reports the license with `withholds`, e.g. DCMS withholding
  `drives` and `firmware inventory` on a Supermicro X10 with only SFT-OOB-LIC. `ipmi`
  knows no licenses and has no `get_licenses`.

### Changed
- Requires napalm-device-types 4.15 (`LicenseDict.withholds`).
- `get_device_warnings` still reports `bmc_license_required` / `bmc_license_partial` for
  callers that do not read `get_licenses` yet; it goes once netOrk derives both.

## [0.4.0] - 2026-10-17

### Added
- `bmc` NAPALM driver (`napalm_redfish.bmc:BmcDriver`): the best of Redfish and IPMI for
  one BMC, chosen by itself. It reads over Redfish where the BMC answers. A BMC that refuses
  Redfish altogether (no license) is read and switched over IPMI, and a getter that fails
  over Redfish is asked over IPMI where IPMI has it; IPMI is opened only then. Power control
  goes over Redfish when it answers. A refusal by the BMC is not retried over IPMI. The BMC
  itself is reset over Redfish only. `get_device_warnings` adds `ipmi_fallback` to
  `bmc_license_required` while it reads over IPMI. `get_management_protocols` over IPMI
  reports IPMI over LAN on, the one thing it knows. Same account for both; `ipmi_port`
  (623) in `optional_args`.

### Changed
- Discovery suggests `bmc` for a BMC it finds: the fingerprint rules and the probed
  `/redfish/v1/` path moved from `RedfishDriver` to `BmcDriver`
  (`BMC_PORT_SPECS`, `BMC_HTTP_FINGERPRINT`). `redfish` stays for choosing by hand.

## [0.3.1] - 2026-10-17

First run against real hardware over Redfish: a Supermicro X10DRL-i (BMC 3.91) with the
SFT-OOB-LIC license only, recorded under `tests/fixtures/supermicro-x10drl-i-3.91/redfish/`.

### Fixed
- A resource the BMC refuses for want of a further license (403 `OemLicenseNotPassed`) no
  longer fails the whole getter. The transport raises `RedfishFeatureLicenseError` (a
  `RedfishAuthError`); `get_hardware_inventory` reads the drives from `SimpleStorage`
  instead of a withheld `Storage`, and `get_firmware_inventory` falls back to the BMC
  firmware (`Managers/{id}`) and the BIOS (`Systems/{id}.BiosVersion`) when `UpdateService`
  is withheld.
- The model of a system that reports a placeholder ("Super Server" on Supermicro) is the
  board: the system's `PartNumber`, else the chassis model.

### Added
- `get_device_warnings` reports `bmc_license_partial` with the licenses the BMC names and the
  parts it withholds (`drives`, `firmware inventory`).

## [0.3.0] - 2026-10-17

### Added
- `IpmiDriver.set_power_state`: the server's power over IPMI chassis control (`On`,
  `GracefulShutdown`, `ForceOff`, `ForceRestart`). `get_power_state` now offers those the
  server accepts in its state (`On` when off, the other three when on). IPMI has no
  graceful restart, and pyghmi offers no power cycle; neither is offered. The driver
  still does not reset the BMC. This is for boards that offer nothing but IPMI, such as a
  Supermicro X10 without a Redfish license.

## [0.2.1] - 2026-10-13

### Added
- `IpmiDriver` and `RedfishDriver` mix in `HealthMetricsMixin`: netOrk's SNMP health
  poll reads the BMC's own load, memory and interfaces (UCD-MIB) where the BMC runs
  net-snmp, as the Supermicro X10's does. The role base stays without it.

### Fixed
- `IpmiDriver`: the second poll of a BMC in the same process failed with
  `'<' not supported between instances of 'float' and 'NoneType'`. pyghmi files a
  session in `Session.initting_sessions` under the credentials as str but deletes it
  only under bytes, so the next `Command` got the old, logged-out session back. The
  driver drops that entry itself before `open()` and after `close()`. Reproduced and
  verified live against a Supermicro X10DRL-i (three polls in one process).

## [0.2.0] - 2026-10-13

### Added
- `ipmi` NAPALM driver (`IpmiDriver`) on `ManagementControllerDriver`, read-only, over IPMI
  2.0 with `pyghmi`: facts and inventory from the FRU (manufacturer, product, serial number,
  system UUID), the BMC's LAN interface, temperatures, fans and power supplies from the
  sensor records, the power state, the system event log and the BMC firmware version. No
  power control and no BMC reset. For BMCs that refuse or lack Redfish; IPMI over LAN leaks
  password hashes (CVE-2013-4786), so it is the fallback, not the main path.
- Recorded IPMI fixtures from a Supermicro X10DRL-i (BMC 3.91).

### Changed
- A BMC that refuses Redfish for want of a vendor license no longer fails `open()`.
  `get_facts` returns what is known without Redfish, `get_device_warnings` reports
  `bmc_license_required` with the licenses the BMC names, and every other getter raises
  `ConnectionException`. A poll therefore reports the missing license instead of an
  offline BMC.

## [0.1.2] - 2026-10-13

### Fixed
- The fingerprint rules are grouped into alternatives (one Redfish answer, one landing
  page), so discovery's maximum for this driver is 21, not 41. With every alternative
  summed, a Supermicro landing page (6 of 41) lost to a bare "linux" in the BMC's own
  SNMP sysDescr (5 of 18). Requires napalm-device-types 4.8.

## [0.1.1] - 2026-10-13

### Fixed
- Discovery no longer takes every device with an open HTTPS port for a BMC: the
  `PortSpec` for 443 carries no weight, so a switch's web UI scores nothing.
- A BMC that refuses Redfish for want of a vendor license (Supermicro X10 without SUM,
  DCMS or OOB answers even `GET /redfish/v1/` with 403 `OemLicenseNotPassed`) now fails
  `open()` with `RedfishLicenseError` naming the licenses, not with a bare status code.

### Added
- Fingerprint rules for the BMC web UIs netOrk's discovery already fetches: Supermicro
  X9-X11 (ATEN firmware), iDRAC, iLO. A rule for a Redfish error body
  (`@message.extendedinfo`) for when discovery reads the service root.
- Recorded fixtures from a Supermicro X10DRL-i (BMC 3.91, unlicensed).

## [0.1.0] - 2026-10-13

### Added
- `redfish` NAPALM driver (`RedfishDriver`) on `ManagementControllerDriver` from
  napalm-device-types 4.7, registered as the `napalm.drivers` entry point `redfish`
- NAPALM getters for the BMC: `get_facts`, `get_interfaces`, `get_interfaces_ip`,
  `get_environment` (fans, temperatures, power supplies; `cpu` and `memory` empty),
  `get_users`, `get_ntp_servers`, `get_snmp_information`
- Role methods for the managed server: `get_power_state`, `set_power_state`,
  `get_hardware_inventory`, `get_event_log`, `get_firmware_inventory`,
  `get_management_protocols`; `reboot_host` resets the BMC (`Manager.Reset`)
- HTTPS transport on the DMTF `redfish` library: Redfish session login with the session
  deleted on close, basic auth fallback only when sessions are unsupported, certificate
  verification on by default (`verify_ssl` accepts a CA file), collections followed by
  `@odata.id` including `nextLink` pages, links to other hosts refused
- Environment from `ThermalSubsystem`/`PowerSubsystem`/`Sensors` where present, legacy
  `Thermal`/`Power` otherwise
- Pure parsers for every resource in `docs/redfish-map.md`
- Tests against DMTF Redfish mockups (public-rackmount1, public-localstorage,
  public-telemetry) over mocked HTTP

### Known limitations
- Not yet run against real hardware; Supermicro X10 behaviour is from the design notes
- No `ipmi` fallback driver yet
- `get_config` is not implemented (a BMC has no configuration file)
