Release 0.7.1

Fixes

• Fix stack unwinding past Reset function (#337)

Release v0.7.0

New Features

• Add support for CMSE secure gateway veneers (#297).
• Allow using the crate with custom target JSON specs (#304).
• Export Exception enum for other crates to use (#224).

Fixes

• Various fixes to the linker script (#265, #286, #287, #323).
• Use the correct ABI for the main symbol (#278).
• Add barriers after FPU enabling (#279).
• (ARMv6-M) Set LR value to a known value on reset (#293).
• Added CFI and size info to external assembly subroutines (HardFaultTrampoline and FpuTrampoline) (#294).
• Allow building the crate for macOS targets (#306, #310).
• Perform RAM initialization in assembly, to avoid potential UB in Rust (#301).
• Perform volatile reads of ICSR in DefaultHandler (#315).

Breaking Changes

• Make ExceptionFrames fields private, adding setters and getters instead (#239).
• Only allow certain attributes on handlers, and apply them to the trampoline too (#228).
• Make it unsafe to define exception handlers for NMIs (#289).
• Check that exceptions exist on the target chip when registering a handler for them (#308).

Other

• Change macros crate to use same version number as cortex-m-rt crate (#245).
• Discourage use of pre_init in documentation (#248).
• Backport: Use links in Cargo.toml to prevent multiple linking of cortex-m-rt (#276).

Backport Release v0.6.15

Fixed

• Backport: Mark .bss as NOLOAD (#265)
• Backport: Fix possible overflow of .data region (#286)
• Backport: Perform volatile reads of ICSR in DefaultHandler (#315)

Other

• Backport: Use links in Cargo.toml to prevent multiple linking of cortex-m-rt (#276)
• Backport: Use same verison for macros crate as for cortex-m-rt itself (#245)

Backport Release v0.6.14

Fixed

• Backport: Allow building the crate for macOS targets (#306, #310).

Backport Release v0.6.13

Fixed

• (ARMv6-M) Set LR value to a known value on reset (as the ARM spec requires)
• Added CFI and size info to external assembly subroutines (HardFaultTrampoline)

Backport Release v0.6.12

Fixed

• Fixed lint warnings getting emitted on macro-generated code.

Release v0.6.11

Changed

• Macros now generate a second trampoline function instead of randomizing the function's symbol name. This makes the build deterministic.
• [breaking-change] static mut resources no longer have 'static lifetime except in the #[entry] function (this is a soundness fix; see #212).

Release v0.6.10

Fixed

• Linker template now takes and discard *(.ARM.exidx)

Release v0.6.9

Added

• Input .uninit.* sections are now collected into an output .uninit section. Uninitialized static variables are meant to be placed in these sections. The output .uninit section is not initialized by the runtime.

Release v0.6.8

Fixed

• Correct stack-pointer is selected on HardFault
• Linker template now takes and discard *(.ARM.extab.*)
• Misc. documentation fixes

Changed

• Architecture added: armv8-m.main
• Cortex-M team added to authors
• The nightly build is allowed to fail in CI
