Simple Machines is pleased to announce the release of SMF 2.1 RC3. Bugs that were reported after the release of RC2 have been fixed and improvements have been made to security, stability, and performance. The many fixes and improvements include the following:

- Enhanced privacy policy support.
- Several important enhancements to PostgreSQL and MySQL.
- Multiple hooks added for handling data and/or presentation.
- Language files now uses sprintf() whenever possible.
- Theme enhancements/fixes.
- Improvements on Admin session checks.
- Enhancements on security: tokens, hashing cookies and better session handling.
- Multiple calendar fixes/enhancements.
- Better hashing system for the image proxy.
- Bug fixes for alert notifications.
- Added unsubscribe links for announcement emails.
- PHP 7.4 support.
- Several misc bug fixes/improvements.
- Download of posts/PMs/profile for GDPR.

This release is considered to be an RC (Release Candidate), which means that it is sufficiently functional, but that it has known and unknown bugs. These bugs do not necessarily prevent a release, rather they need to be addressed before the next dev cycle release.

SMF RC3 can be installed as a brand new installation, or an SMF 2.0.x installation can be upgraded to SMF RC3, however, please do note that there are no updates packages for any RC releases.

We highly encourage testing this version on local or development/QA environments. Testing the release will greatly help us in narrowing down, and focusing on, issues/improvements towards the Final release... However, we do not recommend using an RC package on any live installation and/or production forum due to the very nature of RC packages.

Finally, this announcement topic is not for support. Please use the SMF 2.1 support board instead.

A very special thanks goes to our code contributors, Teamies, and non-Teamies whose reports and pull requests have greatly helped us not only to reach our goals, but also to create/grow/improve our development cycle. 

Thank you for using SMF!

Kind regards,
Simple Machines

Nice!!  Well done :D



The end is only for those who do not stop halfway.
Let's move on!

GREAT news, congrats and thank you! My forum shares hosting with a few Wordpress sites, and lately WP has been grumbling about the outdated PHP version that I've kept due to the SMF2.0.17 7.2 limitation. I may soon update to 2.1. My forum is small and very basic, so a hiccup here or there would not be a big problem for us.


Congrats Team on this release!

Is there a list of features that default 2.1 RC3 have which 2.0.17 doesn't?

That rant topic has been going for awhile now, but contrary to popular belief, it was about communication, and not specifically RC3's release. We all love SMF, and are very happy that progress is being made. :)


Congratulations to all Team.
