The first release of binpatch is out. Three years have passed since the first time binpatch saw the light, building binary patches for OpenBSD 3.1 and four years since the messages that started it all.
Back then binary patches for OpenBSD was a crazy idea. Nowadays a hand of different proposals have arised, each of them with its own particular approach. binpatch's approach is to be true to the OpenBSD philosophy of simplicity.
This release comes with documentation and a sample Makefile to help you create your own binary patches.
