The release announcement above has some interesting back-of-the-envelope calculations for the wall-time required to crack a master key from a LUKS keyslot with PBKDF2 vs Argon2id.
And they also link to Matthew Garrett’s article, which describes how to manually upgrade your (non-TAILS) LUKS header to Argon2id.
