v8.4.4

• #304 via #309: Refactored cheroot.connections.ConnectionManager to use selectors.BaseSelector.get_map and reorganized the readable connection tracking — by @liamstask.
• #304 via #309: Fixed the server shutdown sequence to avoid race condition resulting in accepting new connections while it is being terminated — by @liamstask.

v8.4.3

• #282: Fixed a race condition happening when an HTTP client attempts to reuse a persistent HTTP connection after it's been discarded on the server in cheroot.server.HTTPRequest but no TCP FIN packet has been received yet over the wire — by @meaksh.

  This change populates the Keep-Alive header exposing the timeout value for persistent HTTP/1.1 connections which helps mitigate such race conditions by letting the client know not to reuse the connection after that time interval.

v8.4.2

• Fixed a significant performance regression introduced in
  v8.1.0 (#305 via #308) - by @mar10.

  The issue turned out to add 0.1s delay on new incoming
  connection processing. We've lowered that delay to mitigate
  the problem short-term, better fix is yet to come.

v8.4.1

• Prevent ConnectionAbortedError traceback from being printed
  out to the terminal output during the app start-up on Windows
  when built-in TLS adapter is used (#302 via PR #306) - by @mxii-ca.

v8.4.0

• Converted management from low-level select() to high-level selectors (#249 via PR #301) - by @tommilligan.

  This change also introduces a conditional dependency on selectors2 as a fall-back for legacy Python interpreters.

v8.3.1

• Fixed TLS socket related unclosed resource warnings (PR #291 and PR #298).
• Made terminating keep-alive connections more graceful (#263 via PR #277).

v8.3.0

• cherrypy/cherrypy#910 via #243: Provide TLS-related
  details via WSGI environment interface.
• #248: Fix parsing of the --bind CLI option
  for abstract UNIX sockets.

v8.2.1

• cherrypy/cherrypy#1818: Restore support for None
  default argument to WebCase.getPage().

v8.2.0

• Deprecated use of negative timeouts as an alias for
  infinite timeouts in ThreadPool.stop.
• cherrypy/cherrypy#1662 via #74: For OPTION requests,
  bypass URI as path if it does not appear absolute.

v8.1.0

• Workers are now request-based, addressing the
  long-standing issue with keep-alive connections
  (#91 via #199).
