• ChangeLog

• Changes in version 2.2.1-alpha (21 May 2023)
  
   Libevent 2.2.1-alpha includes a number of new features and performance
   improvements.
  
   The log below tries to organize them by rough area of effect.
  
   This release contains around 1000 patches (without merges) with 151 new
   contributors!
  
   This changelog omits some commits which were pure bugfixes on other commits
   listed below. typos, some minor CI changes and similar things.
  
   Some keywords highlights of this major release:
   - wepoll backend (by Nick Grifka)
   - signalfd backend (by Dmitry Antipov)
   - DNS over TCP for evdns (by ayuseleznev)
   - websockets layer (by Dmitry Ilyin)
   - "prepare" and "check" watchers (by Dan Rosen)
   - MbedTLS support (okhowang)
   - unix domain sockets for HTTP
   - cmake over autotools/automake
   - extensive CI
  
   For more detail, see the git changelogs. For more insight, see the
   "whatsnew-2.2.txt" document included in the Libevent 2.2.1-alpha
   distribution.
  
   SSL layer gains MbedTLS support, and had been tested with LibreSSL too. And
   of course with OpenSSL 1.1/3.0.
  
   From now on, the autotools is considered as deprecated, and you should use
   cmake instead.
  
   And now we are using github actions for CI, previously we had travis-ci for
   linux/macos and appveyor for win32 (removed in #951), and also I used testing
   vagrant for some time, but it had been moved into a separate repository
   (8c1838be). But actually this is not required anymore since github actions
   supports:
   - linux
   - freebsd
   - windows
   - macos
   - openbsd
   - and also tests under Thread/Address/Undefined sanitizers
  
   Now documentation is automatically deployed to https://libevent.org/doc/
