Removed '**Animated progress bars don't work in Opera 12**—as they don't support CSS3 animations.' note.
Bootstrap 4 doesn't (and doesn't need to) support the ancient Opera 12 released in 2012 with a 0.04% marketshare so no need to mention.
* Prevent print utils from overriding all other display utils
Fixes#25221.
I agree with the referenced issue—this is unexpected and also causes a serious bug when mixed with other utility classes. This wasn't an issue in v3 given we had different utilities for hiding that weren't focused on display property.
* Add printing changes to migration docs
* unrelated heading sentence case change
* List out all .d-print- classes
When changing `$input-border-width`, `$input-height-border` does not change and `select.form-control` `custom-select` `custom-file` will still have `$input-height` which is resolved from `$input-btn-border-width`
This will work in cases when want controls with border, and buttons without.
Temporary fix will be to override 2 variables
```
$input-border-width: 2px !default;
// which is
// $input-height-border: $input-btn-border-width * 2 !default;
$input-height-border: $input-border-width * 2 !default;
```
