• Implemented getline_hr () and column_names () (RT#34474)
  (suggestions accepted from Mark Stosberg)
  
• Corrected misspelled variable names in XS
  
• Functions are now =head2 type doc entries (Mark Stosberg)
  
• Make SetDiag () available to the perl level, so errors can
  be centralized and consistent
  
• Integrate the non-XS errors into XS
  
• Add t/75_hashref.t
  
• Testcase for error 2023 (Michael P Randall)
  
• Completely refactored the XS part of parse/getline, which
  is now up to 6% faster. YMMV
  
• Completed bind_columns. On straight fetches now up to three
  times as fast as normal fetches (both using getline ())
