Livecode 10.0.0dp5 new reserved words

[Paul Dupuis]

Does anyone, including folks at the mothership, have a list of new 
reserved words in Livecode 10?

I have used a variable called "tExt" (t for temp, Ext for extension)  to 
pull of the file extension from file paths. i.e. if tFile contains 
"C:/users/paul/desktop/image.png"

set itemDel to "."
put last item of tFile into tExt -- tExt contains "png"

However, in LC 10.0.0dp5, the word "tExt" (which is "text") now appears 
to be a reserved work and you can not use it as a variable. This is not 
true in LC 9.6.9.  This has me asking: Are there any other new reserved 
words I should refactor out of my code before I get mysterious errors?
