The bug mentioned in these two related questions (94496) and (113527) seems to be fixed in different versions.
On Windows, the bugfix version is 11.0.0. On MacOS, reading the comments, it is 10.4.0.
For each of these questions, I am wondering whether this:
Bug introduced in ... and fixed in 10.4.0 (MacOS) and 11.0.0 (Windows)
would be an appropriate form.
How the bug banner should be written for OS-dependent bugfix version?
From a quick search, OS-dependent bugs do not seem to be an issue, the OS specification being either part of the question (see, e.g., (16683) and (111719)) or part of the banner (see, e.g., (89152)).
Update 1. Following the comment of ilian, I would propose instead something like
Windows: Bug introduced in ... and fixed in 11.0.0
MacOS: Bug introduced in ... and fixed in 10.4.0
Update 2. (Follows QuantumDot comment) Bug banner standardization was discussed before in this post, but the case I mentioned here was not addressed previously as far as I know.
Would there be any advantages of having a standard header for these cases as well?
