switch to a current coding standard (PER2) to make the code more readable and consistent with other projects
create a class diagram (in Mermaid embedded in Markdown) to help us understand the system
make the code coverage publicly visible, add a link or badge from the README to the code coverage reports, and have a tool report the effects of PRs on the code coverage numbers
do some automated code cleanup (using Rector)
rename internal things (including parameter names) to ditch the Hungarian notation
every now and then test the latest development version with Emogrifier
release version 9.0.0
