perl-IO-Socket-SSL/IO-Socket-SSL-2.052-use-system-default-SSL-version.patch
Paul Howarth 1a5e9cfa4d Update to 2.052
- New upstream release 2.052
  - Disable NPN support if LibreSSL ≥ 2.6.1 is detected since they've replaced
    the functions with dummies instead of removing NPN completly or setting
    OPENSSL_NO_NEXTPROTONEG
  - t/01loadmodule.t shows more output helpful in debugging problems
  - Update fingerprints for external tests
  - Update documentation to make behavior of syswrite more clear
