*) wireless - fixed AES encryption speed issues (upgrade suggested);
On 6rc? this did great things in some situations for me.
Uldis, why you first post have only two lines? CHangelog have 6lines
Now no NV2 freezing with 5.24

why don’t you guys write full change reports ? ? ?
Is their any changes regarding NV2?
Looks like the v5.23 and v5.24 changelog mixed together that is why you see 6 lines.
There are some few fixes for Nv2 that will increase the stability so If you are using Nv2 we recommend to upgrade the AP and the Clients to this version.
If you still see some lockups please report back and write to support.
Every time something is omitted from the changelog, a kitten dies.
will help a little spreading the torrent 
I see in changelog

ROS 5.23 and ROS 5.24 start problem with protocol ssh in mpls , when is used pptp.
H1----R1–(MPLS)—R2–(MPLS)—R3—(MPLS over pptp)–R4—H2
Host H1 can’t connect to host H2 used ssh.
Interesting first-hand notice of ROS 5.24 and RB2011.. On the spur of the moment I decided to try MetaROUTER after upgrade. I imported same OpenWRT image as earlier, made same basic setup as earlier and started to load it, just like I have done several times before (with different ROS versions).
BUT! This time is totally different than those previous times, because after 1,5 hours I have lost exactly Zero (0) packets from my datastream. Time period is not so long that no-one can say anything sure, but so far this seems very stable. Response times for ping are varying from <1ms to ~10ms (mostly <1 as it should be of course).
Previous times I had constant freezes every ~10 minutes or so, so something has changed somewhere. My device is exactly in same room and in same temporature and in same load and in same everything than earlier.
Edit: Have to say that I didn’t try MT with 5.23, because I had other problems and I was forced to downgrade back to 5.22.
Edit#2: Ok, had first freeze after 2 hours, so forget. Everything is like before.
What exactly is this change? Can I please get more info on this?
how about wds and ospf?
with 5.24 and nv2 we have a lockup when data gets to 40mbs tx and 40mbs rx simultaneously
must then disable and enable the link
Upgrade from 5.23 to 5.24 yesterday and it seems that I can’t see the graghing any more on: routerIP/graghs - It just shows a blank page below “Traffic and system resource graphing” headend.
I’ve enabled graghing as I did on 5.23 release but I can’t see the graphs any more! 
Can you replicate it with a simple bandwidth test?
Where is 5.23 ?
Have you changed MPLS MTU to make it work over pptp tunnel? PPTP adds overhead and reduces MTU.
