Thread:Extension talk:ParserFunctions/Are there ANY issues I should know about when updating from the last Extension:StringFunctions?

I am still using Extension:StringFunctions (version 2.0.3, Nov 30, 2008) and an old version of parser functions from about that time (v1.1.1). So I wonder what has improved in the mean time and will everything still work as expected? Are there any changes from including StringFunctions into Parser functions? Of course I could try, but I have lots of templates and very likely things would look normal for a while until somebody stumbles into some wrong template functionality where nobody knows where it could come from, requiring some ugly bug solving. Would be thankful for any information on that.
