New version 3.1 → 3.3

Refresh older workouts. • When you import a file again, you can now replace the existing workout: zones, best efforts and TSS are recalculated, title and sport stay. The preview shows the previous TSS first. • Several files at once: Debrief re-imports workouts that already exist after a single confirmation. • This way, GPX and TCX runs from before 3.2 get the more accurate pace zones too. • Importing several files: a note when GPX rides contain no power data. • More accurate fitness curve when replacing workouts around midnight. As long as you don't re-import anything, all existing values stay unchanged.
