Haproxy 1.6-dev2 正式发布，更新内容如下：
- DNS-based server name resolution : haproxy is now able to periodically
ask a set of resolvers for the IP address of some servers and to update
them without restarting. This will make life much easier for people
running in AWS where IP address change randomly. Some more stuff was
planned for this such as marking the server as unresolvable if resolving
fails, but we found that people would probably like to have a configurable
behaviour. Feedback on this is desired and will drive the next steps.
- peers protocol v2 : haproxy 1.6 and 1.5 will not be able to synchronize
their stick tables but on the other hand the new protocol is much better
and more extensible. First it uses a single connection regardless of the
number of tables to synchronize. Second it will support synchronizing
much more than just stick tables. For now it replicates all stick-tables
contents (including gpc, etc...). This allows reloads to keep entries,
rates, etc... as well as to pass them to a backup node in case of a
switchover. It's very likely that during 1.7 development we'll further
extend the amount of information that can be exchanged
