Development for Lotus notes and Domino, looking for learning resources?

Question

Web development

Good afternoon.
I'm starting to work as a junior developer for Lotus notes and Domino. I will write for versions 8.5 and 9, but most of the literature found on the net refers to earlier versions. How significant are the differences between versions, and also advise resources, literature for development. The language doesn't matter.
Thank you very much.

Answer 1

The main source of information is the "red shelf" IBM, en.wikipedia.org/wiki/IBM_Redbooks
From the current Russian-language forums, you can advise sysadmins.ru/forum30.html
The main changes between versions are listed in en.wikipedia.org/wiki/IBM_Lotus_Notes
Use old documentation , as a rule, it is possible (with certain reservations), because Lotus, despite all the changes, tries to maintain compatibility with previous versions as much as possible. Those. if there is no new documentation, then the old + fresh release notes are much better than nothing.
From a very, very old one, everything that Nikolai Iontsev wrote is recommended.
