CHANGELOG for crate multiboot2

0.16.0 (xxxx-xx-xx)

• Add TagTrait trait which enables to use DSTs as multiboot2 tags. This is mostly relevant for the command line tag, the modules tag, and the bootloader name tag. However, this might also be relevant for users of custom multiboot2 tags that use DSTs as types. See the example provided in the doc of the get_tag method.
• renamed MULTIBOOT2_BOOTLOADER_MAGIC to MAGIC
• added a builder feature and a builder module with a builder::InformationBuilder struct
• EFIMemoryDesc was removed and is now an alias of uefi_raw::table::boot::MemoryDescriptor
• EFIMemoryAreaType was removed and is now an alias of uefi_raw::table::boot::MemoryType
• MSRV is 1.68.0

0.15.1 (2023-03-18)

• BREAKING MemoryMapTag::all_memory_areas() was renamed to memory_areas and now returns MemoryAreaIter instead of impl Iterator<Item = &MemoryArea>. Experience showed that its better to return the specific iterator whenever possible.
• BREAKING MemoryMapTag::memory_areas() was renamed to available_memory_areas (Sorry for the breaking changes in a minor release, but I just stumbled upon this und since the last breaking release was just yesterday, users have to deal with changes anyway.)
• BREAKING ElfSection::name() now returns a Result instead of just the value. This prevents possible panics.
• fix: prevent a possible panic in ElfSection::section_type()

0.15.0 (2023-03-17)

• BREAKING MSRV is 1.56.1
• BREAKING fixed lifetime issues: VBEInfoTag is no longer &static
• BREAKING: TagType is now split into TagTypeId and TagType
  • TagTypeId is a binary-compatible form of a Multiboot2 tag id
  • TagType is a higher-level abstraction for either specified or custom tags but not ABI compatible.
  • There exists a seamless integration between u32, TagType, and TagTypeId via From and PartialEq-implementations.
• fixed another internal lifetime issue
• BootInformation::framebuffer_tag() now returns Option<Result<FramebufferTag, UnknownFramebufferType>> instead of Option<FramebufferTag> which prevents a possible panic. If the --unstable feature is used, UnknownFramebufferType implements core::error::Error.
• Fixed misleading documentation of the BootInformation::efi_memory_map_tag
• BootInformation now publicly exports the get_tag function allowing you to work with custom tags. An example is given in the function documentation. (check docs.rs). There is also a small unit test that you can use to learn from.

0.14.2 (2023-03-17)

• documentation fixes
• MbiLoadError now implements Display
• Added the unstable feature, which enables nightly-only functionality. With this feature, MbiLoadError now implements core::error::Error and can be used with anyhow::Result for example.

0.14.1 (2023-03-09)

• fixed the calculation of the last area of the memory map tag (#119) (Previously, iterating the EFI Memory map resulted in a superfluous entry as it ran over the next tag)

0.14.0 (2022-06-30)

• BREAKING CHANGES \ This version includes a few small breaking changes that brings more safety when parsing strings from the multiboot information structure.
  • BootLoaderNameTag::name now returns a Result instead of just the value
  • CommandLineTag::command_line now returns a Result instead of just the value
  • ModuleTag::cmdline now returns a Result instead of just the value
  • RsdpV1Tag::signature now returns a Result instead of an Option
  • RsdpV1Tag::oem_id now returns a Result instead of an Option
  • RsdpV2Tag::signature now returns a Result instead of an Option
  • RsdpV2Tag::oem_id now returns a Result instead of an Option
• internal code improvements

0.13.3 (2022-06-03)

• impl Send for BootInformation

0.13.2 (2022-05-02)

• TagType now implements Ord so that it can be used in BTreeSet
• small internal improvements and restructuring of the code (no breaking changes to public API)

0.13.1 (2022-01-09)

• minor fix

0.13.0 (yanked)

• added missing getters for tag ImageLoadPhysAddr
• added missing getters for tags EFIImageHandle32 and EFIImageHandle64

0.12.2 (2021-10-02)

• TagType now implements Eq and Hash
• internal improvements
  • std can be used in tests; the crate is still no_std
  • this implies that cargo test doesn't work on "non-standard" targets
  • CI (Ubuntu) still works.
  • code formatting/style
  • sensible style checks as optional CI job
  • .editorconfig file
  • prepared co-existence of crates multiboot2 and multiboot2-header in a Cargo workspace inside the same repository

0.12.1 (2021-08-11)

• TagType-enum introduced in v0.11 is now actually public
• internal code improvements

0.12.0 (2021-08-06)

• breaking: load() and load_with_offset now returns a result
• added public constant MULTIBOOT2_BOOTLOADER_MAGIC
• Rust edition 2018 (instead of 2015)
• internal code improvements

0.11.0 (2021-07-07)

• breaking: iterator functions (e.g. ElfSectionsTag::sections()) return impl Iterator instead of a concrete type
• lib now contains TagType-enum that contains all possible mbi tags that are specified (taken from spec)
• much improved debug-formatting of BootInformation
• internal code improvements / formatting

0.10.0 (2020-11-03)

• allow access to all memory regions (MemoryMap-Tag)
• internal code improvements

0.9.0 (2020-07-06)

• Add a checksum_is_valid method to the RSDP tags (#64)

0.8.2 (2022-03-02)

• Add some basic documentation (#62)
• Add MemoryAreaType, to allow users to access memory area types in a type-safe way (#61)
