Diesel 2.0.0 RC1

We are happy to announce the release of Diesel 2.0.0 RC1

This release contains a number of fixes and improvements compared to the previous 2.0.0 RC0 release.

Notably the following fixes and improvements are included:

• A fix for an issue preventing connection reuse with the built-in r2d2 integration
• Support for types from the ipnet crate
• Support for loading values via libpq's row by row mode
• Improvements to error messages generated by #[derive(Insertable)] for the case of type mismatches

This release hopefully marks the last prerelease before a stable 2.0.0 release.
We plan to release the final 2.0.0 soon after this, as long no other blocking issues are found.

Thank you to everyone who helped make this release happen through bug reports, and discussion on Gitter. While we don't have a way to collect stats on that form of contribution, it's greatly appreciated.

• Chris Eckhardt
• Emile Fugulin
• Iban Eguia Moraza
• Jean SIMARD
• Martin Nordholts
• Otto Castle
