We have tagged the current SBI specification as a release candidate for
v0.3[1]. It is tagged as v0.3-rc1 which includes few new extensions and
cosmetic changes of the entire specification.
Here is a detailed change log:

- New extensions:
- SBI PMU extension
- SBI System reset extension
- Updated extensions:
- Hart Suspend function added to HSM extension
- Overall specification reorganization and style update
- Additional clarifications for HSM extension and introduction section
- Makefile support to build html & pdf versions of the specification

We don't expect any significant functional changes. We will wait for
any further feedback and release the official v0.3 in a month or so.

Thank you for your contributions!
