Navigator 3.00 was the version that came to define Navision for many years. For the first time we now have a full integrated development environment (IDE) and the first version of C/AL, just called AL. This now allowed partners to change almost every corner of the system, including building new feature rich add-ons.
AL Programming Language.Design tools (object designers): Tables, Forms Reports, Codeunits and Dataports
Released in the fall of 1989.
Service releases created in 1990
General version released in 1991. This version included many minor fixes and functionality tweaks. This was the product first named "Navision" (core was still called Navigator), and really is the product that put PC&C and Navision on the map.
First version to run on IBM's OS/2 operation system as well as IBM's AIX on a RISC6000.
If any versions should be kept in Navision's Hall-of-Fame, then Navision 3.04 is one of them. It was very stable, no new versions was released for two years - next was version 3.50.
