The last update to the R3000 compiler was in early 2008, with v9.62.The last update to the R4/5/6000 compiler was in 2012 with v10.72. And there have been no new Rabbit modules for quite some time.
Does anyone have a sense of whether the Rabbit product line is over? Digi continues to sell the existing products, and supplies tech support for those products, but I don't see any ongoing efforts to improve or expand the product line.
The R3000 is capable of addressing more than the 512K that the largest R3k module allows. Why no new R3K modules with more memory? The R3k compiler has plenty of bugs. Why no bug fixes, or updates to the compiler?
Same with the R6000 line.
