Section 3.2 says:

      However, if the mod-sequence of any metadata item of the message
      is greater than the specified UNCHANGEDSINCE value, then the
      requested operation MUST NOT be performed.  In this case, the
      mod-sequence attribute of the message is not updated, and the
      message number (or unique identifier in the case of the UID STORE
      command) is added to the list of messages that failed the
      UNCHANGESINCE test.

      When the server finished performing the operation on all the
      messages in the message set, it checks for a non-empty list of
      messages that failed the UNCHANGESINCE test.  If this list is
      non-empty, the server MUST return in the tagged response a
      MODIFIED response code.  The MODIFIED response code includes the
      message set (for STORE) or set of UIDs (for UID STORE) of all
      messages that failed the UNCHANGESINCE test.

   Example 3:

      All messages pass the UNCHANGESINCE test.

      C: a103 UID STORE 6,4,8 (UNCHANGEDSINCE 12121230045)
          +FLAGS.SILENT (\Deleted)
      S: * 1 FETCH (UID 4 MODSEQ (12121231000))
      S: * 2 FETCH (UID 6 MODSEQ (12121230852))
      S: * 4 FETCH (UID 8 MODSEQ (12121130956))
      S: a103 OK Conditional Store completed

It should say:

      However, if the mod-sequence of any metadata item of the message
      is greater than the specified UNCHANGEDSINCE value, then the
      requested operation MUST NOT be performed.  In this case, the
      mod-sequence attribute of the message is not updated, and the
      message number (or unique identifier in the case of the UID STORE
      command) is added to the list of messages that failed the

      message set (for STORE) or set of UIDs (for UID STORE) of all
      messages that failed the UNCHANGEDSINCE test.

      S: * 1 FETCH (UID 4 MODSEQ (12121231000))
      S: * 2 FETCH (UID 6 MODSEQ (12121230852))
      S: * 4 FETCH (UID 8 MODSEQ (12121130956))
      S: a103 OK Conditional Store completed

Notes:

This erratum changes "UNCHANGESINCE" to "UNCHANGEDSINCE" in four places.
