Dyalog today announced that version 15.0 is now available on all platforms and includes performance enhancements, new system functions, improved look and feel and a new RIDE (and lots more!)

NOTE: Personal/Non-Commercial use of Dyalog APL is now completely free. The non-commercial system is a fully functional 64-bit Unicode interpreter, except on the Raspberry Pi where it remains a 32-bit application.
