v0.4.23

0.4.23 is the next 0.4 release of the popular chrono date and time library for Rust. After the 0.4.20-0.4.22 series that brought chrono back to life after a long hiatus, development has been fairly quiet, allowing us to start planning changes for the 0.5.0 release. As such, we've started deprecating some APIs that are likely to be removed in 0.5. If you have any feedback on these changes, please let us know in the issue tracker!
