The FreeCAD wiki is very good. The release notes for 26.3 are at https://wiki.freecad.org/Release_notes_26.3 and those entries link to relevant sections of the wiki that go into more detail. For example, changes to the Measurement tool on that page link to https://wiki.freecad.org/Std_Measure where you'll see notes like "introduced in 26.3".
The wiki tells you what the tools do. For learning how to use those tools to model something, YouTube channels like Mango Jelly's are a better bet. The pace of FreeCAD development has definitely picked up since the 1.0 release
