This release includes some dependency updates, but the center piece is a bigger update for lestrrat-go/jwx:
This might introduce some breaking changes, if you rely on specific jwx behavior (functionality introduced with 1.6.0 of jwtcache-go). This is unfortunate, but the breaking change is part of jwx, so this is mostly mitigation work.
On the other hand, we adjusted the supported Go range to 1.15.X and 1.16.X, effectively dropping Go 1.13.X and 1.14.X. We would have liked to keep 1.14.X, but again jwx now required 1.15.X as a minimum, so we had to follow for the time being.
