+Introduction of assumed-valid blocks
+-------------------------------------
+
+- A significant portion of the initial block download time is spent verifying
+ scripts/signatures. Although the verification must pass to ensure the security
+ of the system, no other result from this verification is needed: If the node
+ knew the history of a given block were valid it could skip checking scripts
+ for its ancestors.
+
+- A new configuration option 'assumevalid' is provided to express this knowledge
+ to the software. Unlike the 'checkpoints' in the past this setting does not
+ force the use of a particular chain: chains that are consistent with it are
+ processed quicker, but other chains are still accepted if they'd otherwise
+ be chosen as best. Also unlike 'checkpoints' the user can configure which
+ block history is assumed true, this means that even outdated software can
+ sync more quickly if the setting is updated by the user.
+
+- Because the validity of a chain history is a simple objective fact it is much
+ easier to review this setting. As a result the software ships with a default
+ value adjusted to match the current chain shortly before release. The use
+ of this default value can be disabled by setting -assumevalid=0
+
+Fundrawtransaction change address reuse
+----------------------------------------
+
+- Before 0.14, `fundrawtransaction` was by default wallet stateless. In
+ almost all cases `fundrawtransaction` does add a change-output to the
+ outputs of the funded transaction. Before 0.14, the used keypool key was
+ never marked as change-address key and directly returned to the keypool
+ (leading to address reuse). Before 0.14, calling `getnewaddress`
+ directly after `fundrawtransaction` did generate the same address as
+ the change-output address.
+
+- Since 0.14, fundrawtransaction does reserve the change-output-key from
+ the keypool by default (optional by setting `reserveChangeKey`, default =
+ `true`)
+
+- Users should also consider using `getrawchangeaddress()` in conjunction
+ with `fundrawtransaction`'s `changeAddress` option.
