There is a new command that allows you to kill jobs other admins have left running:

/System script job print
/System script job remove numbers=1

There is also the addition of BFD:

BFD protocol for routing
Starting from RouterOS version v4.4, BFD is
supported.
BFD is a protocol intended to detect faults in the
bidirectional path between two forwarding engines,
including physical interfaces, subinterfaces, data
link(s), and to the extent possible the forwarding
engines themselves, with potentially very low latency.
It operates independently of media, data protocols,
and routing protocols.
Bidirectional Forwarding Detection (BFD):
* hello protocol for checking bidirectional neighbor
reachability;
* provides sub-second link failure detection support;
* not routing protocol specific, unlike protocol hello
timers or such
Features supported:
* asynchronous mode (draft-ietf-bfd-base-09.txt)
* BFD timer and detection multiplier configuration per
interface;
* enabling BFD for OSPF interfaces
* enabling BFD for BGP peers
* single hop IPv4 and IPv6 transport (draft-ietf-bfdv4v6-
1hop-10.txt)
* multihop IPv4 and IPv6 transport (draft-ietf-bfdmultihop-
08.txt)
Using it:
OSPF:
/routing ospf interface add interface=all use-bfd=yes
BGP:
/routing bgp peer add remote-address=x.x.x.x remoteas=
xxxxx use-bfd=yes
BFD timer configuration:
/routing bfd interface
BFD neighbor status:
/routing bfd neighbor

Wikipedia has more on it here.
It appears to be a standalone mechanism that establishes a connection after a 3way handshake. So, if you have two pieces of gear connected, this little protocol will connect between the gear and ensure the link is still up.
