+Subject: [PATCH 3/3] m-reserve-device: replace the hash table key on new
+ insert
+
+We're using the WpReserveDevice's name as key in the hash table, so we
+must update the key as well when we replace an item in the hashtable -
+the old device (and its name) will be released.
+
+The side-effect of this is that the *third* device with an identical
+name will no longer replace the previous device. This results in the
+following sequence:
+
+- dev1 added: name Audio0
+  - dev1 requests name owner Audio0
+- dev2 added: name Audio0
+  - replace dev1 in the hashtable
+     - dev1 emits "release" signal
+     - dev1 unowns the Audio0 name
+  - dev2 requests name owner Audio0
+- dev3 added: name Audio0
+  - adds to the hashtable because the existing key is now undefined
+  - dev3 requests name owner Audio0
+     - error, you cannot request ownership for the same name twice
+
+Fixes #93

+Subject: [PATCH 2/3] policy-node: wait for nodes when we become unlinked
+
+If we were linked before but our node is removed, wait until a new node
+becomes available instead of failing.
+
+This fixes an issue where there is only 1 sink available and the card
+profile is toggeled between pro and stereo. After the profile is
+toggled, the sink is removed and the node would be killed with an error
+because there is no fallback sink. The fix is similar to the
+pipewire-media-session logic.
