Ah, just found that the change in PHP 8.0.10 is due to fixing bug
#79580. Apparently, when the day-of-year is parsed before the
given year, the day-of-year is applied to the current year.

As of PHP 8.0.10, it is no longer possible to use "z.Y" at all ("A
'day of year' can only come after a year has been found"). Fixing
the unsupported format to "Y.z" brings the desired results[1].
So this is a documentation problem.

Possible workaround:
$ php -r 'echo DateTime::createFromFormat("z Y", "59 2016")->format("Y-m-d"), PHP_EOL;'
2016-03-01
$ php -r 'echo DateTime::createFromFormat("Y z", "2016 59")->format("Y-m-d"), PHP_EOL;'

$ php -v

Why is this still an issue 2.5 years later?
I see it in 5.5.12 on Ubuntu 14.10 and 5.6.5 on Windows Server 2012.
