- 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
- comb through the existing tests, make them more fine-grained, clean them up and divide them into unit tests (which test only one class at a time) and functional tests (which test the whole system)
- add proper dedicated getters and setters to OutputFormat and drop/deprecate the dynamic property accesses and magic methods
- add more basic unit tests so we have at least the basic functionality covered
- announce on social media that we are looking for more contributors (and possibly co-maintainers, if the collaboration is constantly good)
- add a Composer script to re-create the class diagram
- automate the Doxygen-generated documentation
- go through the open PRs one by one, from old to new, decide if we want to have it at all, and re-create it with good test coverage (and then merge it)
- go through the open tickets and categorize or close them
- fix the bugs reported in the tickets
- drop or enforce usage of
mb_*methods - add logging
- drop the switch for the lenient mode and instead use the behavior that matches what browsers do
- use PHP 7.2 language-level code features (using Rector)
- add native type declarations (using Rector)
- raise the PHPStan levels one by one and fix all warnings
- add extra-strict PHPStan rules and fix all warnings
- set up mutation testing using Infection, go through the findings, and add test for the most important missed things
- add a PHPStan extension for cognitive complexity and refactor the code to be easier to grok
- make the types less ambiguous and more strict
- find and fix the worst performance bottlenecks
- every now and then test the latest development version with Emogrifier
- release version 9.0.0
