Frequently Asked Questions:

What should I do if I’m using R36 or R37 packages?
Nothing – these versions are confirmed safe as they rely on API versions <45, which do not adopt ICU locale formatting.

Will my custom components break due to ICU enablement?
No, as long as they use API <45.0. However, it is still advisable to perform sandbox testing to detect any formatting inconsistencies.
