Goodmorning, I have a project developped whith V4.74 and now I would like to install V5.20, but I'am unable to find the corresponding legacy support. On www2.keil.com/.../ the latest version listed the legacy support package V5.18. May I use legacy V5.18 together with V5.20 or do I have to wait until the correct legacy pack is available? Do I generally need a legacy support package after updating from older version? Thank you.
