Is The Automatic Update For Unicode Whitespace in Member and Alias Names Part of 26.04

Summary:

In the 26.04 monthly updates under Important Actions and Considerations, there is a note about Unicode Whitespace in Member and Alias Names. While I never used or relied on leading, trailing spaces or unicode whitespaces, I wanted to ask some questions to ensure there are no issues with this update on my end.

1. Is this update part of 26.04 or a future update?
2. What do you mean by automatic? Do I now need to "Validate" the metadata when I import from EDM using the Validate button / Is the validation part of refreshing the database and an error will return if there is a unicode whitepace?
