This is a service release which corrects a few issues found in the R16B03 release. The corrections are:

  • The ODBC application was missing in the prebuilt Windows installers
  • 3 corrections in the SSL application:
    • Add missing validation of the server_name_indication option and test for its explicit use.
    • Elliptic curve selection in server mode now properly selects a curve suggested by the client, if possible.
    • The server did not indicate support for secure renegotiation during TLS extension handling.
  • In the syntax tools application a bug was introduced which broke reverting of local funs. This is now corrected (thanks to Anthony Ramine)
  • wx - Solved a problem which caused the debugger to crash when closing a window. Fixed static linking on Mac.
  • xmerl - Fixed a problem in the SAX-parser when the header of the next document was appearing in the buffer when using the xmerl_sax_parser:stream/2 function.
