Release Notes

Note to users who created volumes with 1.17 version of VeraCrypt or earlier:
To avoid hinting whether your volumes contain a hidden volume or not, or if you depend on plausible deniability when using hidden volumes/OS, then you must recreate both the outer and hidden volumes including system encryption and hidden OS, discarding existing volumes created prior to 1.18a version of VeraCrypt.
