How did you customize your Bootstrap 4 files Tom?
You usually have two options:
- changing the bootstrap Sass variables and compiling it
- using a CSS overwrite file, to overwrite the settings you won’t
When Wappler updates Bootstrap 4 files - it does just a timestamp check of the files. So only newer files are replaced. That is indeed unfortunate when we deliver a new version of Bootstrap 4 - you current will get overwritten.
So if you compile it on your own you will just need to recompile it with the new version,
If you were using method 2 and just having overwrites, then you shouldn’t need to change anything.
