 ## WIP
 * Switch from PHP CS Fixer to PHP CodeSniffer for coding standards
+* Create class constants for the debug levels in the POP3 class
+* Improve French, Slovenian, and Ukrainian translations
 
 ## Version 6.1.8 (October 9th, 2020)
 * Mark `ext-hash` as required in composer.json. This has long been required, but now it will cause an error at install time rather than runtime, making it easier to diagnose
