• native-tls is now optional (thanks to @TheDutchMC) and the new rustls-based TLS backend added to the library. Please see the "SSL Support" section in the crate docs.
• now the buffer pool is lock-free and optional (controlled by the buffer-pool feature). Please see the "Buffer Pool" section in the crate docs.

  • mysql_common/bigdecimal replaced with mysql_common/bigdecimal03

• chrono, time and uuid reexports are removed
