E'' strings are the proper way to embed backslash escapes in strings and are unaffected by this change.
Discuss general development subjects that are not specific to a particular version like the versioning control system we use or other infrastructure.

On deeper inspection this seems to only apply to "special" escape sequences like \a which we should not be using. The thing to check would be \n in strings I would think.
