Just installed it, still getting the warning message "This is a changed programmer from the TL866CS!!"
When mine isn't! it still shows as a TL866A though in the programme, unsure yet if anything has been gimped.
This doesn't sound good. Does it still work? I have v6.60, works fine for me, without warnings.
For tools, IDEs etc., usually I follow the principle "if it ain't broke don't fix it", meaning if I don't need a new feature, I don't update (if the program is not security related, like the operating system, which of course needs to be updated all the time, or other internet connected programs). Just yesterday I used the programmer for an ATTiny25 and it supports the parallel programming mode, and all fuse settings in the "Config" tab, without problems, so I can set the fuse for the reset pin etc. and don't brick it. Doesn't matter much for a price of 0.70 cents per IC, but easier to develop if you can do lots of iterations and tests without fearing to pay like one postage stamp per test
