# ISSUES:
|
|
#
|
|
# - There are some repos who maintain different major versions over
|
|
# some time in specific branches and that the release not on
|
|
# master/main/whatever but on these version branches. This may
|
|
# result in issues when using the sorting of tags retrieved by this
|
|
# script somewhere else.
