RELEASE NOTES
Version 4.7.1
=============
- New requirements:
- uses stdbool and stdint as part of z3.h
- New features:
- none
- Removed features:
- none
- Notes:
This is a minor release prior to a set of planned major updates.
It uses minor version 7 to indicate that the use of stdbool and
stdint are breaking changes to consumers of the C-based API.
Version 4.6.0
=============
