pfSense 2.0.1 release is now available. About half the mirrors are synced at the time of posting this, and the remainder will be synced in the next few hours. This is a maintenance release with some bug and security fixes since 2.0 release. This is the recommended release for all installations. As always, you can upgrade from any previous release to 2.0.1, so if you haven’t upgraded to 2.0 yet, just upgrade straight to 2.0.1. For those who use the built in certificate manager, pay close attention to the notes below on a potential security issue with those certificates.

Notes for certificate generation vulnerability
Certificates generated with the built-in certificate manager in all 2.0 versions prior to 2.0.1 are excessively permissive for non-CA certificates. These certificates can be used as a certificate authority, meaning a user can use their own certificate to create chained certificates. We have defaulted OpenVPN on 2.0.1 and newer versions to not accept chained certificates, which mitigates this. However, if untrusted users have certificates generated from 2.0 release, we suggest re-generating all your certificates and issuing new ones. Certificates generated by easy-rsa and imported into 2.0 are not affected.
If using certificates generated on pfSense for other purposes, you should revoke those and issue new certificates generated on 2.0.1. You must utilize a CRL in that case. To be on the safe side, you may want to start from scratch with a new CA and certificates after deleting all your existing ones if this applies to you.
Thanks to Florent Daigniere for bringing this issue to our attention and helping confirm our resolution.
It is very important to read the upgrade guide before performing an upgrade for those still on 1.2.x versions.
Files for new installs available here on the mirrors.
NOTE: With 2.0 release and newer versions, we’re now also building the oft-requested nanobsd embedded version with VGA! You’ll find alternate builds with VGA in the filename, which are the VGA-enabled versions. Only use these on hardware with VGA video. The regular serial version must be used on all hardware that has only a serial port, like the popular PC Engines and Soekris models amongst others, as they will not boot or function correctly otherwise.
