The Debug formatter output was recently changed in #30967 to always include a decimal point, and apparently some crates' test suites depends on the exact output of the formatter. I don't know if it's worth to revert the change, but I reported it just in case.

• caldyn regressed from stable to beta (crater log)
• earlgrey regressed from stable to beta (crater log 1 and crater log 2)
• euclid regressed from stable to beta (crater log 1 and crater log 2), but it's fixed on master
• expecttest regressed from stable to beta (crater log), but it's fixed on master
• mkv regressed from stable to beta (crater log)
• postgis regressed from stable to beta (crater log)
• pretty_assertions regressed from stable to beta (crater log), but it's fixed on master
• scanlex regressed from stable to beta (crater log)
• spectral regressed from stable to beta (crater log)
• vectors regressed from stable to beta (crater log)
