# Application Binary Interface for the Arm® Architecture
This is the official place for the latest documents of the Application Binary
Interface for the Arm® Architecture, both for source files and officially
released documents.
## Releases
The latest ABI releases are being made available only here on Github:
https://github.com/ARM-software/abi-aa/releases and are licensed under the
Creative Commons Attribution-ShareAlike 4.0 International License + grant of
Patent License.
If there is no entry in the change history table for a release, there are no
changes to the content of the document for that release.
Previous versions of the documents were released under a proprietary license on
developer.arm.com. These are now hosted in this repo, and are to be found under
the legacy documents folder. They follow the same folder naming scheme as the
main document folders.
See the links to the individual documents in the *Document locations* section below.
## Defect reports
Please report defects in or enhancements to the specifications in this folder to
the [issue tracker page on
GitHub](https://github.com/ARM-software/abi-aa/issues).
For reporting defects or enhancements to documents that currenlty are not yet
included in this repo and are thus only hosted on developer.arm.com, please send
an email to [email protected].
## Document locations
See the tables below for the status of the various ABI specifications. A dash represents that the document isn't available either as a Github release or as a legacy release.
