Full Changelog: v3.5.0...v4.0.0

v3.5.2

• Handle blank STAT values. (#388)

v3.5.1

• Client.get returns the default when using ignore_exc and if memcached is unavailable.
• Added noreply support to HashClient.flush_all.

v3.5.0

• Sockets are now closed on MemcacheUnexpectedCloseError.
• Added support for TCP keepalive for client sockets on Linux platforms.
• Added retrying mechanisms by wrapping clients.

v3.4.4

v3.4.3

• Fix HashClient.{get,set}_many() with UNIX sockets. (#314)

v3.4.2

• Remove trailing space for commands that don't take arguments, such as stats. This was a violation of the memcached protocol. (#311)

• Added missing HashClient.close() and HashClient.quit().
