-* The Eth2 spec has been upgraded to 1.0.1.
+* We're now consistent with the v1.0.1 Eth2 spec
 
 **We've fixed:**
 
+* A frequent crash occurring on certain hardware configurations after
+  building Nimbus from source.
+
 * Long processing delays triggered by the reception of attestations that
   reference already pruned states.
 
-* LibP2P peer management issue leading to accumulation of inactive
+* LibP2P peer management issue which led to an accumulation of inactive
   connections.
 
 * A false-positive in doppelganger detection triggered by rebroadcasted
   older attestations arriving with a significant delay.
 
+**New features**:
+
+* A new improved format of the slashing protection database:
+
+  - Significantly reduces the disk load with a large number of validators (1000+).
+
+  - Makes it possible to enhance our doppelganger detection in the future such that
+    waiting for 2 epochs before attesting is not necessary.
+
+  To ensure smooth upgrade and emergency rollback between older and future Nimbus
+  versions, v1.0.10 will keep track of your attestation in both the old and the
+  new format. The extra load should be negligible for home stakers.
