Breaking changes in 1.4.5 + missing changelog

Hello,

I tried updating from 1.4.4 to 1.4.5, but all my tests fail with some variations of this message:

WARNING: '--some-filepath--/a.txt' is locked by another process, there are a few common causes for this:
	- Another application accesses this file:
		Nothing you can do about it, it's out of your control.
	- 2 instances of this application run simultaneously:
		Use SingleInstanceManager to restrict running more than one instance.
	- You are calling Update.finalizeUpdate() after launch() and files are already loaded onto JVM:
		Call Update.finalizeUpdate() before launch to complete the update process.
	- You are attempting to update a file that runs in the bootstrap application:
		Bootstrap dependencies cannot typically be updated. For services, leave
		the old in place, just release a newer version with a higher version
		number and make it available to the boot classpath or modulepath.
	- A file that's required in the business application was added to the boot classpath or modulepath:
		Much care must be taken that business application files should NOT be
		loaded in the boot, the JVM locks them and prevents them from being updated.

Are the breaking changes expected?

This is a bug! This change explains it very well.

Used to be I would only check for file lock status, and only on Windows. But this change adds accessibility checks on other platforms as well. This explains why this happens when using 1.4.5 only.

I have to add a simple Files.createDirectories(path.getParent())

No, the update fails.

As marked above the version 1.4.5 of finalizeUpdate replaced FileUtils.verifyNotLocked by FileUtils.verifyAccessible.

Also, I’ve noticed that the update will succeed without issues if I manually create all the sub-directories.
