2020-April

The release contains the following changes:

• requires C++ 14
• eliminates the use of std::auto_ptr, either by removing code in question or by replacing with std::unique_ptr.
• removes the setProperty and getProperty member functions from XMLReader. In the unlikely event you were using them, they can be replaced by setLexicalHandler/getLexicalHandler and setDeclHandler/getDeclHandler. There were some additional properties available if you were using Xerces as the parser - if removing setProperty/getProperty causes you difficulty, please get in touch and I'll reinstate them.
• Removed ParserAdaptor class. Probably never used in the entire history of Arabica. It's the result of enthusiastic (ie overly slavish) conversion from the original Java SAX implementation. There never were any SAX1 Arabica parsers to adapt to
  SAX2.
