Disable the "std" feature and enable the "alloc" + feature. [#138][] [#271][] + +* Added support for DWARF 5 `.debug_rnglists` and `.debug_loclists` + sections. [#272][] + +* Added support for DWARF 5 `DW_FORM_ref_sup` and `DW_FORM_strp_sup` attribute + forms. [#288][] + +* Added support for DWARF 5 operations on typed values. [#293][] + +* A `dwarf-validate` example program that checks the integrity of the given + DWARF and its references between sections. [#290][] + +* Added the `EndianReader` type, an easy way to define a custom `Reader` + implementation with a reference to a generic buffer of bytes and an associated + endianity. [#298][] [#302][] + +### Changed + +* Various speed improvements for evaluating `.debug_line` line number + programs. [#276][] + +* The example `dwarfdump` clone is a [whole lot faster + now][dwarfdump-faster]. [#282][] [#284][] [#285][] + +### Deprecated + +* `EndianBuf` has been renamed to `EndianSlice`, use that name instead.

[#233][] + +* Added more robust error handling in our example `dwarfdump` clone. [#234][] + +* Added `FrameDescriptionEntry::initial_address` method. [#237][] + +* Added `FrameDescriptionEntry::len` method. [#237][] + +* Added the `FrameDescriptionEntry::entry_len` method. [#241][] + +* Added the `CommonInformationEntry::offset` method. [#241][] + +* Added the `CommonInformationEntry::entry_len` method. [#241][] + +* Added the `CommonInformationEntry::version` method. [#241][] + +* Added the `CommonInformationEntry::augmentation` method. [#241][] + +* Added the `CommonInformationEntry::code_alignment_factor` method. [#241][] + +* Added the `CommonInformationEntry::data_alignment_factor` method. [#241][] + +* Added the `CommonInformationEntry::return_address_register` method. [#241][] + +* Added support for printing `.eh_frame` sections to our example `dwarfdump` + clone. [#241][] + +* Added support for parsing the `.eh_frame_hdr` section. On Linux, the + `.eh_frame_hdr` section provides a pointer to the already-mapped-in-memory + `.eh_frame` data, so that it doesn't need to be duplicated, and a binary + search table of its entries for faster unwinding information lookups. [#250][] + +* Added support for parsing DWARF 5 compilation unit headers. [#257][] + +* Added support for DWARF 5's `DW_FORM_implicit_const`. [#257][] + +### Changed + +* Unwinding methods now give ownership of the unwinding context back to the + caller if errors are encountered, not just on the success path. This allows + recovering from errors in signal-safe code, where constructing a new unwinding + context is not an option because it requires allocation. This is a **breaking + change** affecting `UnwindSection::unwind_info_for_address` and + `UninitializedUnwindContext::initialize`. [#241][] + +* `CfaRule` and `RegisterRule` now expose their `DW_OP` expressions as + `Expression`. This is a minor **breaking change**. [#241][] + +* The `Error::UnknownVersion` variant now contains the unknown version + number. This is a minor **breaking change**. [#245][] + +* `EvaluationResult::RequiresEntryValue` requires an `Expression` instead of a + `Reader` now. This is a minor **breaking change**.

[#192][] + +* All the constants from DWARF 5 are now defined. [#193][] + +* Added support for the `DW_OP_GNU_parameter_ref` GNU extension to parsing and + evaluation DWARF opcodes. [#208][] + +* Improved LEB128 parsing performance. [#216][] + +* Improved `.debug_{aranges,pubnames,pubtypes}` parsing performance. [#218][] + +* Added the ability to choose endianity dynamically at run time, rather than + only statically at compile time. [#219][] + +### Changed + +* The biggest change of this release is that `gimli` no longer requires the + object file's section be fully loaded into memory. This enables using `gimli` + on 32 bit platforms where there often isn't enough contiguous virtual memory + address space to load debugging information into. The default behavior is + still geared for 64 bit platforms, where address space overfloweth, and you + can still load the whole sections of the object file (or the entire object + file) into memory. This is abstracted over with the `gimli::Reader` + trait. This manifests as small (but many) breaking changes to much of the + public API. [#182][] + +### Fixed + +* The `DW_END_*` constants for defining endianity of a compilation unit were + previously incorrect. [#193][] + +* The `DW_OP_addr` opcode is relative to the base address of the `.text` section + of the binary, but we were incorrectly treating it as an absolute value.
