 Vyatta release compatiblity
 ---------------------------
-Vyatta Core releases from **6.5** to **6.6** should be 100% compatible.
 
-Vyatta Core **6.4** and earlier may have incompatibilities. In **6.5** the "modify"
-firewall was removed and replaced with ``set policy route`` command family, and
-old config cannot be automatically converted. You will have to adapt it to
-post-6.5 syntax manually.

-.. note:: Also, in **6.5** remote access VPN interfaces were renamed from pppX
-   to l2tpX and pptpX, so if you are using zone-policy in pre-6.5 versions, make
-   sure to change interface names in rules for remote access VPN.
