Have a matrix of iOs and Android library changes in line with code versions. We have recently spent a lot of time trying to work out why our iOs app was crashing when enabling Best Practice Tracking. After some time and discussions with Client care, it appears that this was once a plugin and not compatible with versions pre-v4. By having a release matrix of changes by code version would save us all a lot of time and make understanding implementations much easier.
Developers do not have time time to be reading through reams of release notes and instead a simple quick ref guide would be ideal.
