 Change the `ipfs key list` behavior to log an error and continue listing keys when a key cannot be read from the keystore or decoded.
 
+#### Gracefully skip socket files on add
+
+`ipfs add` previously failed with a misleading "use of closed network connection" error when encountering socket files. It now gracefully skips them.
+
 #### Accelerated DHT Client and Provide Sweep now work together
 
 Previously, provide operations could start before the Accelerated DHT Client discovered enough peers, causing sweep mode to lose its efficiency benefits. Now, providing waits for the initial network crawl (about 10 minutes). Your content will be properly distributed across DHT regions after initial DHT map is created. Check `ipfs provide stat` to see when providing begins.
