++## Upgrading to > 1.2.0 (**PRERELEASE**)
++
++* After v1.2.0 we modified how we invoke `poll(2)` to wait for connections to complete, such that we will now retry
++  the call if it is interrupted by a signal until:
++
++  a) The connection succeeds or fails.  
++  b) The overall connection timeout is reached.
++
++  In previous versions, an interrupted `poll(2)` call would cause the connection to fail 
++  with `c->err` set to `REDIS_ERR_IO` and `c->errstr` set to `poll(2): Interrupted system call`.  
++
+ ## Upgrading to `1.1.0`
+ 
+ Almost all users will simply need to recompile their applications against the newer version of hiredis.

+Subject: [PATCH] Retry poll(2) if we are intterupted.
+
+This commit adds logic to retry our poll call when waiting for the
+connection to complete, in the event that we are interrupted by a
+signal.
+
+Additionally we do some simple bookkeeping to keep track of the overall
+timeout specified by the user.
