  • wildcard certificate mtching with multiple subdomains in configuration
  • diff of TCP listener configuration

0.11.1 - 2019-05-06

Changed

  • activate jemallocator and link time optimization
  • sozuctl now uses the buffer size defined in the configuration file

Removed

  • procinfo dependency

0.11 - 2018-11-15

breaking changes:

  • the public_address field for listeners is now an Option<SocketAddr>, so it's configuration file format is IP:port instead of just an IP address
  • the AddHttpsFront message does not use a certificate fingerprint anymore, so HTTPS frontends do not depend on certificate anymore

Added

  • unit tests checking for structure size changes
  • more error handling in sozuctl
  • new automatic_state_save option to store the configuration state automatically after changes
  • event notification system: by sending the SUBSCRIBE_EVENTS message, configuration clients can get regular notifications, like messages indicating backend servers are down

Fixed

  • 100 continue behaviour was broken in 0.10 and fixed in 0.10.1
  • sticky session cookies are now sent again
  • Forwarded headers now indicates correct adresses

0.10.0 - 2018-10-25

breaking change: modules have been moved around in sozu-lib

Added

  • sozuctl has a "config check" command
  • sozuctl shows the backup flag for backends
  • sozuctl shows more info for TCP proxys

Removed

  • sozuctl displays an address column for backends, instead of IP and port

Changed

  • new code organization for sozu-lib, with everything related to protocol implementations in src/protocol
  • refactoring of the HTTP protocol implementation
  • in preparation for HTTP/2, the pool now handles instances of Buffer, not BufferQueue

Fixed

  • work on TCP proxy stability
  • reduce allocations in the HTTP parser
  • integer underflow when counting backends in the master state
