The Live edition of Zenwalk Linux 7.4 has been announced and it does away with the OpenSSL Heartbleed issue and other problems. This Zenwalk Linux release also does away with the AuFS-enabled kernel.
Zenwalk Live 7.4 does a UnionFS file-system in user-space via FUSE with the Slackware Linux kernel in place of AuFS.
Zenwalk Live 7.4 is also likely to be the last distribution release with the 32-bit system support. This new release is also a DVD-ROM release rather than fitting to the constraints of a CD for the Slackware-based Linux distribution.
There's also other fixes and improvements that will be found via Zenwalk Linux Live 7.4 via the official release announcement
