Org Mode version 9.0 has been released and is ready for update. Take a look at the Changes file to see what’s new. I’ve had it installed for less than an hour as I write this so it’s a little too early to draw any conclusions.
The only issue I’ve had to deal with is the new Export block syntax. That’s explained near the top of the Change file and basically involves writing things like
#+BEGIN_EXPORT html #+END_EXPORT
instead of
#+BEGIN_HTML #+END_HTML
The shortcuts (<h Tab in this case) will give you the proper syntax so you need worry only about fixing up old files that you want to export. Happily, the Change file includes a bit of Elisp that will do that for you. I just pasted it into my init.el file for the time being so that I can easily fix any files I need to. That would mostly be old blog posts that I want to post an update to but there are a couple of others that I’ll need to fix the next time I export them.
There are a few other non-backward compatible changes but they probably won’t affect many people. Be sure to look at beginning (at least) of the Changes file to make sure you aren’t affected.
Many thanks to Bastien and the other developers for all their hard work. Org keeps getting better and better and I wouldn’t be nearly as productive without it.
