• Net-SSLeay now requires at least Perl 5.8.1. This is a
  formalisation of what has been the de facto case for some time,
  as the distribution hasn't compiled and passed its tests on Perl
  5.005 for several years.
  
• Increment Net::SSLeay::Handle's version number to keep it in sync
  with Net::SSLeay's, thus satisfying Kwalitee's consistent_version
  metric.
  
• Re-enable the d2i_X509_bio() test in t/local/33_x509_create_cert.t
  for LibreSSL. Thanks to Alexander Bluhm.
  
• Automatically detect new library names on Windows for OpenSSL
  1.1.0 onwards (libcrypto, libssl). Fixes part of RT#121084. Thanks
  to Jean-Damien Durand.
  
• Fix a typo preventing OpenSSL libraries built with the VC compiler
  (i.e. ones with a ".lib" suffix) from being automatically detected
  on Windows. Fixes part of RT#121084. Thanks to Jean-Damien Durand.
  
• Add missing call to va_end() following va_start() in TRACE().
  Fixes RT#126028. Thanks to Jitka Plesnikova.
  
• Added SSL_in_init() and the related functions for all
  libraries and their versions. All return 0 or 1 as
  documented by OpenSSL 1.1.1. Use of these functions is
  recommended over using constants returned by get_state() and
  state(). New constants TLSST*, used by OpenSSL 1.1.0 and
  later, will not be made available by Net::SSLeay.
