+RPC importprivkey: new label behavior
+-------------------------------------
+
+Previously, `importprivkey` automatically added the default empty label
+("") to all addresses associated with the imported private key. Now it
+defaults to using any existing label for those addresses. For example:
+
+- Old behavior: you import a watch-only address with the label "cold
+ wallet". Later, you import the corresponding private key using the
+ default settings. The address's label is changed from "cold wallet"
+ to "".
+
+- New behavior: you import a watch-only address with the label "cold
+ wallet". Later, you import the corresponding private key using the
+ default settings. The address's label remains "cold wallet".
+
+In both the previous and current case, if you directly specify a label
+during the import, that label will override whatever previous label the
+addresses may have had. Also in both cases, if none of the addresses
+previously had a label, they will still receive the default empty label
+(""). Examples:
+
+- You import a watch-only address with the label "temporary". Later you
+ import the corresponding private key with the label "final". The
+ address's label will be changed to "final".
+
+- You use the default settings to import a private key for an address that
+ was not previously in the wallet. Its addresses will receive the default
+ empty label ("").
