What does 'through/before' mean here?
There is a little difference between them:
- "through" means "until and including"
- "before" means "until" without including
For example,
- through 4.10.15: versions before 4.10.15 and version 4.10.15
- before 4.10.15: versions before 4.10.15
The meaning of "before" is usually in terms of numerical order. However, it is advisable to read the Linux kernel versioning
