I have not been able to find any clear descriptions: what are the major differences from v2 to v3. What are the notable improvements? Any breaking changes?
I have long been using v2.46 for all my installers. Will upgrading to the latest v3 keep compatibility with all older installers? Can/should I keep v2 and v3 installed side by side on same machine?
NSIS v3 differences from v2

Unicode support is the big change. There are some security changes so some 3rd-party plug-ins might not work but NSIS 2.5x has this same issue. We have tried to not make breaking changes so hopefully everything will just work.
You can keep as many side by side versions as you want, the only issue is that MakeNsisW stores the recent file list in the registry so that list will be shared by all versions.
