  • gen_statem a new state machine behavior
  • mnesia_ext: plugin of external storage solutions to mnesia
  • crypto: uses EVP interface in OpenSSL resulting in generally better performance and support for HW acceleration
  • ssh: performance improvements, uses the new gen_statem behavior
  • ssl: enhanced error log messages
  • dialyzer: the support for maps is very much extended both the type specification syntax and the type analysis.
  • erts:
