Hi there,

As the title suggests, \iff used in math mode will increase indentation
level while it is not supposed to behave like this. I have briefly
skimmed through the code and it seems to be related to the new function
LaTeX-indent-commands-regexp-make introduced in 0ce906c. The relevant
code is:

(funcall func
              LaTeX-indent-begin-list
              "if[a-zA-Z@]*\\b"
              'LaTeX-indent-begin-regexp-local)

Best,
Ruiyang
