New APL+Win Features Database extended (03nov18)

The New APL+Win Features Database which you can access from the Support horizontal menu has been extended to now include all new features and changes brought to APL+Win since its very first release (1.0) when the product name was still APL*PLUS III. This database allows you to:

  • find when a new feature has been added to APL+Win
  • see when a particular APL+Win feature has been changed or improved
  • search for any keyword and find the corresponding records in the database
  • see all features added or changed in a particular release
  • search by categories like: New Primitive or Enhanced System Function
  • see and search for bug fixes
  • etc.
Note: because of the size of the database, the New APL+Win Features Database page takes a few seconds to load.
