Remark 15.90.20. In [Beauville-Laszlo] it is assumed that $f$ is a nonzerodivisor in $R$ and $R' = R^\wedge $, which gives a glueing pair by Lemma 15.90.6. Even in this setting Theorem 15.90.16 says something new: the results of [Beauville-Laszlo] only apply to modules on which $f$ is a nonzerodivisor (and hence glueable in our sense, see Lemma 15.90.10). Lemma 15.90.19 also provides a slight extension of the results of [Beauville-Laszlo]: not only can we allow $M$ to have nonzero $f$-power torsion, we do not even require it to be glueable.
