if u find 3.249 good for your purpose why bother to change to a newer version i use the older version and it fully support my use of programming and i havnt had any problems so far with older version of it so i dont upgrade at this point since i havnt been in need for support of never pics yet
I agree 3.249 is a good, stable version. I saw it used for professional projects of significant complexity with no reported problems.
Some users are just
obsessed with having the very latest version for whatever irrational reason. Sometimes the newest version does offer some new capability like compatibility with the ICD2.
