There’s a “Zip Archive” link on the bottom of https://bbpress.trac.wordpress.org/browser/branches/plugin – this will be the latest development version.
Just keep in mind, while 2.1 is general stable, it’s still beta so make a backup of things first!
Do you have an approximate ETA when 2.1 will come out of beta and be officially released as a plugin?
jjj is the primary/lead developer for bbPress so he might be able to give you a more specific answer.
Right now there are only 3 remaning tickets for 2.1 (https://bbpress.trac.wordpress.org/query?status=assigned&status=new&status=reopened&group=status&milestone=2.1) so my guess would be sooner than later.
Just thought I’d post back in the event anyone else is considering doing the same but it hesitant:
Installation was seamless, and I have had no problems what-so-ever running it.
Awesome, thanks for reporting back. If you find any bugs please come back and report them 
Having trouble installing 3786.
Extracted everything. Renamed plugin to bbpress. Put bbpress in zip archive bbpress.zip
From WP Admin > Plugins > Add New > Upload
Selected bbpress.zip
Selected Yes from “update existing plugin” dropdown (I am using Easy theme and plugin updgrades https://wordpress.org/extend/plugins/easy-theme-and-plugin-upgrades/ )
Clicked upload.
Getting this message:
Unpacking the package…
Installing the plugin…
Destination folder already exists. ...../wp-content/plugins/bbpress/
Plugin install failed.
Please help!
I’m I really can’t say because I use SVN to sync up with the latest version. Maybe jjj will have some input.
@OC2PS
I was testing and got the same error message using the standard upload (didn’t use the plugin you have listed) but after I clicked on Installed Plugins and went back to try it again, it went through fine. At that point, I see two bbpress installs listed with the 2.0.2 version active and 3786 inactive.
Very strange.
I ended up overwriting my installed bbpress files with new ones via FTP. JJJ says you should delete all bbpress files and then write the new ones there.
