Hi, I managed to update my tiny tutorial on Spec to Pharo 7.0. Can you folks please take a look and let me know if I'm doing something unidiomatic/wrong - it's been quite a while since I coded in Smalltalk? http://www.bahmanm.com/2013/11/spec-part-i-basics.html https://www.bahmanm.com/2013/11/spec-part-ii-layout.html Thanks in advance.
