Today (2018-07-31) we have reached the "Software String Freeze" deadline. Beyond this deadline there should not be any changes in strings.
If you want to help with translations, please check the packages that follow Fedora release cycle (Main projects): https://fedora.zanata.org/version-group/view/main
The deadline for translations is 2018-08-28 (Software Translation Deadline). See the translation schedule[1] for more detail.
