Signatures are more reliable than offsets, for your information.
Offsets change at each update. Signatures are based on bytes, and won't change by magic unless code has been changed in this area.

If the current known signatures have changed, it's because Valve has updated their compiling tools recently and because the jump was big (gcc v2 -> v4), a lot of changes have happened. That's something which happens one time.

Offsets are generally for testing purpose only.
