Full Changelog: v1.0.0...v1.1.0

v1.0.0

The nim-libp2p library has been used in production for over a year in high-stake scenarios, so its core is considered stable. Some modules are more recent and less stable.

The versioning follows semver, with some additions:

Some of nim-libp2p procedures are marked as .public., they will remain compatible during each MAJOR version
The rest of the procedures are considered internal and can change at any MINOR version (but remain compatible for each new PATCH)
We aim to be compatible at all times with at least 2 Nim MINOR versions, currently 1.2 & 1.6
