Hi, I watch BBC World News Today every day and I have made a scheduled script to download it automatically. My command is
I have added an option
to download the newest episode. However I found it there were two episodes yesterday. If I just want to download one episode, the most latest added one, I should I do? Would you consider adding a function to choose to download just the latest added without specifying how many hours ago added?

I don't see any compelling reason to add a new option just to deal with an edge case like this. You're merely seeing a quirk in scheduling that has World News Today broadcast twice on Fridays, on two different channels. Just run a slightly different command on Saturdays by adding --channel="BBC Four" or --channel="BBC News" to select only one of the Friday broadcasts.

Ah! I see! Thank you so much

From v3.03 you can now pick out only the latest episode with --sort=available --sortreverse --limit-matches=1

Wow, love you!!!
