Hello,

For the second time in the last 2 years we have issues with your module and your way of updating. When you updated the module from 6.6.0 to 6.8.0, you jumped the stdlib module from < 8.0.0 to >= 8.0.0. According to semver, this should be a major update. Because in the higher stdlib versions, a lot of deprecated functions are removed.

We will be going through all of our modules very soon to move the lower bounds of stdlib back to 7.0.0 instead of 8.0.0. We apologize for any breakage/inconvenience this has caused you.
