This patch slightly changes the behavior of the `AUDIOBOOKSHELF_UID` and
`AUDIOBOOKSHELF_GID` options. Instead of defining a default user and
group, trying to modify files and silently failing if the filesystem
mode cannot be changed, this patch will just skip the entire process in
the first place.
If these options are defined, Audiobookshelf should behave exactly as
before. If they are not defined, Audiobookshelf will now cause fewer
file modifications (or less failures when trying to modify files).
If this patch gets applied, it should probably be highlighted in the
release notes. This usually shouldn't cause problems for migrations
since the Docker guides explicitly configure the options and the
package installations do not seem to use this at all, but there is still
a change that it will and users should be aware of that.
If a problem arises, users can easily fix the problem by either setting
the permissions once manually to the audiobookshelf user or by simply
defining the `AUDIOBOOKSHELF_UID/GID` options.
Sometimes, a book belongs to more than one series. If you listen to and
finish such a book, Audiobookshelf will list the next book in “Continue
Series” twice, right next to each other. That is not helpful.
This patch fixes the problem by not adding books to the list if they are
already in the list.
This patch changes the books displayed in “Continue Series”, avoiding
books if another book from the series is played back right now. This
prevents Audiobookshelf suggesting books to which users will not listen
to because they are still listening to the last one.
Once a book is finished, the next book in the series will pop still be
suggested to the user.
This fixes #1382
