Hi,

Here is a little heads up: in order to support Pharo 9, I made a change in a couple of my libraries/frameworks (using Integer #byteAt: instead of #digitAt:) that requires Pharo 7.0.5 (released recently) as minimum version.

If you are unable or unwilling to upgrade, you can patch this by adding the follow alias to Pharo versions < 7.0.5:

Integer>>#byteAt: index
 ^ self digitAt: index
