Up until now, pressing on the Share button was opening a menu allowing you to select the information you wanted to Share.
For example you could share a short message on social networks with the episode title, description and URL, but also the complete episode description, the downloaded file, ...
Those options are still available but, you can select the default share mode that will be triggered when pressing on the Share button.
For example you can set the app to still offer you all the sharing option, or to share the episode URL, or to Share as an Instagram Story, ...
The default action is the most popular sharing mode amongst Podcast Addict's users which is sharing a small message limited to 240 characters. This is the best option to share an episode on Social Networks.
You can go into Settings/Share to customize this.
The app Sleep Timer wasn't available when Casting an episode.
This is now 'fixed' with this new version.
All the usual features including lowering the volume right before the sleep timer will end playback and Shaking to reset the sleep timer are available.
The sleep timer can be enabled at any time manually but there was also a setting called 'Always ON' that was enabling the sleep timer any time an episode was being played.
This option still exists but it has been renamed as 'Auto enable' and improved so it can enable itself depending on the time.
For example, you can set the app to enable the Sleep Timer automatically between 10pm and 2am. This also works when using the Chromecast.
You can now press on the Sleep timer button when it's enabled and press on the '+ 5 minutes' button to quickly increase the sleep timer duration.
The Restore process has been improved.
If you try to manually restore a backup, the app will now ask you if you want to restore a local file or a cloud backup.
The app also allows you to select which backup you want to restore from the cloud.
Of course this is only useful if you signed-in into your account.
Support for mp3 files' chapters has been improved.
The app can now show custom images at any time while playing an episode with chapters.
Up until now the app was showing those images as chapters...
Thanks a lot to @marcoarment for the help (documentation and sample file).
