The following is a complete list of changes made between iSymphony 3.1.3 and iSymphony 3.1.4. 

Resolved Bugs

• Resolved an issue that would cause client sessions to leak memory. These leaks could lead to JVM heap exhaustion and trigger OutOfMemoryErrors, causing the panel to become unstable and possibly trigger high CPU usage.
• Resolved an issue that would cause the system to deadlock, and hang, when communication with the Asterisk server was lost.
• Resolved an issue that would cause the Asterisk server connection socket to lock up indefinitely, when the network connection was severed unexpectedly. This would prevent any re-connection attempts to the Asterisk server, and would cause call state in the client to hang.
• Resolved an issue that would cause the chat system to stop functioning and prevent users from receiving chat messages.
• Resolved an issue that would cause errors to be thrown when sorting by Call Status, in the Users Widget.
• Resolved an issue that would cause the message "Loading Recordings" to appear indefinitely in the Recording Widget, if no recordings were available on the system.
• Resolved an issue that would prevent white space from being removed on entered username and password values, before executing login requests for the client or administrator. 
• Resolved an issue that would cause a delay when performing attended transfers or parking calls in the panel.
• Resolved an issue that would prevent updating of Asterisk channel variables and throw UnsupportedOperationExceptions, when new channels were added in Asterisk.
• Resolved an issue that would cause excessive log entries when issues occurred parsing recording file names or performing CDR lookups for non-existent channel IDs. 
• Resolved an issue that would prevent proper sorting of queue calls by position, if the number of calls in queue exceeded 9.
• Resolved an issue that would prevent license activation errors from reporting properly in the administrator.
• Resolved an issue that would prevent the license activation area, in the administrator, from re-enabling on a successful activation.
• Resolved an issue that would cause an error to be thrown when logging out of the panel, if an item was selected in the Recording Widget.
• Resolved an issue where the pause status of an agent would not update when using the FreePBX agent pause feature code.

Improvements

• The client and administrator login forms now trim any whitespace surrounding the entered username and password.
