uefi-v0.37.0

uefi - v0.37.0 (2026-03-22)

Added

• Added proto::ata::AtaRequestBuilder::read_pio().
• Added proto::shell::Shell::{var(), set_var(), vars()}
• Added proto::pci::root_bridge::PciRootBridgeIo::configuration().
• Added proto::pci::root_bridge::PciRootBridgeIo::enumerate().
• Added proto::nvme::pass_thru::NvmePassThru::broadcast().
• Added proto::media::block::BlockIO2.
• Added proto::device_path::DevicePath::to_pool().
• Added proto::device_path::DevicePathUtilities::duplicate_path().
• Added proto::pci::enumeration::PciTree::device_path().
• Added revision() and device_type_guid() to Serial protocol
• Implemented Display for DevicePath, DevicePathNode and ScopedProtocol,
  enabling an easy and convenient way to visualize a device path. For example,
  this may print PciRoot(0x0)/Pci(0x6,0x0)/MAC(525400000001,0x1).
  ScopedProtocol only implements Display if the underlying protocol also
  implements Display.
• Added Handle::component_name() and Handle::device_path() to simplify the
  common use-case of querying more information about a handle.
• Added fs::path::Path::join().
• Added Serial::read_exact() and Serial::write_exact()
• CStr16::from_bytes_with_nul(): This is especially useful to transform the
  retrieved value from a UEFI variable into a UCS2 (CStr16) string.

Changed

• export all text::{input, output}::* types
• Changed ordering of proto::pci::PciIoAddress to (bus -> dev -> fun -> reg -> ext_reg).
• Return request with status as error data object for proto::ata::pass_thru::AtaDevice.
• Breaking: SimpleNetwork::wait_for_packet
  • has been renamed to wait_for_packet_event
  • now returns Result<Event> instead of &Event
• Breaking: Http::get_mode_data doesn't consume a parameter anymore and instead return
  an owned value of type HttpConfigData
• Input::wait_for_key_event() now returns Result<Event> rather than an
  Option.
• Pointer::wait_for_input_event() now returns Result<Event> rather than an
  Option.
• Breaking: boot::check_event now consumes &Event rather than Event, removing the
  need for unnecessary Event::unsafe_clone()s.
• MSRV increased to 1.88.
• Breaking: Renamed DevicePath::to_string() to DevicePath::to_string16()
  to better differentiate with the new to_string() coming from the new
  Display.
• Breaking: Renamed DevicePathNode::to_string() to DevicePathNode::to_string16()
  to better differentiate with the new to_string() coming from the new
  Display.
• Fixed potential partial writes in fmt::Write impl for Serial protocol

uefi-raw - v0.14.0 (2026-03-22)

Added

• Added Tcpv4Protocol.
• Added StorageSecurityCommandProtocol.
• Added FirmwareManagementProtocol.
• Added HiiFontProtocol, HiiFontExProtocol.
• Added HiiImageProtocol, HiiImageExProtocol.
• Added HiiStringProtocol.
• Added HiiPopupProtocol.
• Added FormBrowser2Protocol.
• Added new type SerialIoProtocolRevision
• Added new type SerialIoProtocol_1_1 as companion for SerialIoProtocol
  that includes the device_type_guid parameter

Changed

• Switched *const Self to *mut Self in SerialIoProtocol::set_attributes()
• Switched field revision in SerialIoProtocol from u32 to new type
  SerialIoProtocolRevision
