2-Jan-2018 2.3.5

(note: last update was Aug 2015)

• Add configure option --enable-setlibversion set mark the libs with VERS_3.52 Linux only, so any driver built with the libs will work with closed source DM's
• Add persistent storage of isql command line history if readline() is used (thanks Axel)
• Rename some local mutex functions to avoid name clashes
• Assorted fixes (Thanks Markus * 2)
• Fix regression in ini caching
• Make SQLDrivers look in user as well as system odbcinst.ini for driver attributes
• If in use, clear the ini cache when a write is done via SQLWritePrivateProfileString() so the new value is read
• Fix problem with pooling if the environment was released by the application
• Add check for SQL_COLUMN_COUNT in SQLColAttribute
• isql would not display long error messages. Fixed now.
