Revision History

Legacy versions of the documents were released at the Github repository LoongArch-Documentation. These include version 1.00, 2.00 and 2.01.

All changes to the documents in a subsequent release should be declared in their change history section respectively. Timestamps in the form YYYYMMDD should be used for versioning of the individual documents in this folder, and a global version number which correspond to a combination of individual document versions will still be assigned to every new release of this collection.

This global version number will continue to follow the legacy versioning scheme, where a change of the major version (currently 1 and 2) could potentially degrade binary compatibility between objects conforming to these specifications, while a change to the two-digit minor version signifies other bugfixes and improvements.

Please note that we do not expect the major version to change at any time in the forseeable future, and the minor version may increase by more than 1 in a new public release for project management purposes.

I18n

This specification is written in both English and Chinese. In the event of any inconsistency between the same document version in two languages, the Chinese version shall prevail.
