Release Notes
iTach 710-XXXX-05 Release
*******************************

**Intro**
This update introduces two new LED Lighting modes, handles some bugs resulting in connectivity loss between wireless routers/access points, as well as other minor changes.

***Changes from the iTach 710-XXXX-04 Release***

*iTach IR units now have two dedicated LED Lighting modes, wherein a button can be wired into either the second connector alone (single button mode) or into both the first and second connector (two button mode). For more information, see the iTach API specification.

*iTach SL units now support 14400 baud.

*WiFi model iTach units now broadcast gratuitous ARP packets every 3 seconds in order to work around routers which do not accept 802.11b ARP replies and, therefore, operate outside of specifications.

*WiFi model iTach units now work around a reconnection issue with some routers, wherein units would be unable to reconnect to the network after being disconnected.

*WiFi model iTach units are now compatible with all testable router implementations of 128 bit WEP encryption.

*WiFi model iTach units are now capable of accepting WPA passphrases up to 63 characters (up from 32 characters).

Release Notes
iTach 710-XXXX-04 Release
*******************************

**Intro**
This update introduces the new LED Lighting type connector, as well as simplifies the process of unit configuration and fixes minor implementation bugs.

***Changes from the iTach 710-XXXX-02 Release***

*LED Lighting connector is now a choice in the web configuration page for IR connectors, and as well is a valid choice in the set_IR command. For more information, see iTach API specification.

*Units not containing a username and password will no longer prompt you for credential information.

*Fields not used by units, or that are automatically filled by communication with the router (Default Gateway, DNS information etc...) have been removed from the network page.

*Embedded web pages now hide unnecessary fields, helping to prevent misconfiguration of parameters such as the network settings.

*Enabling the configuration lock now activates a message window confirming that a unit must be defaulted to remove configuration lock.

*Fixed a rare occurence wherein a web server would not correctly apply settings saved by the user.

*Fixed a browser interaction problem causing the configuration lock to prevent new settings from being applied in the case that those settings were applied in the same save as the configuration lock.

Release Notes
iTach 710-XXXX-02 Release
*******************************

**Intro**
This update deals with some minor implementation and initialization bugs.

***Changes from the iTach 710-XXXX-01 Release***

*iTach units will now immediately shut down standard I/O when issued a command to initialize learner mode. I/O will resume once learner mode is deactivated.

*WiFi iTach units now run a routine during startup to increase wireless radio initialization, preventing a rare event wherein a WiFi module would fail to initialize.

Release Notes
iTach 710-XXXX-01 Release
*******************************

**Intro***
Several changes have been made to the iTach firmware suite in the new 710 firmware level.

***Changes from the 700 Firmware Level***

*The iTach firmware level has been changed to 710 and the revision level has been returned to 01 for all iTach products.

*iTach units no longer broadcast a terminating period in their IP address(192.168.1.70. -> 192.168.1.70).

*iTach relay connectors will now respond to the getstate command with the state of the connector.

*iTach IR connectors configured as Sensor Notify will now respond to the getstate command with the state of the connector.

*iTach IR codelength has been extended to 260 pairs, or a total of 520 total pulse values.

*The iTach IR repeat value has been extended to 50, and all values outside the legal range of 1-50 will be treated as a value of 50.

*The IR repeat value of 0 has been reinstated for backward compatibility. A repeat count of 0 will play IR commands 50 times.

*iTach units will now broadcast beacon information prior to successfully negotiating a DHCP address. Units in DHCP mode with no DHCP server present are now visible with the iHelp utility.

*iTach units will now hold their IP address after a power cycle. Routers that will not reassign an address when requested will still assign units a new DHCP address.

*Serial Multiconnection Mode has been altered to read input buffers one at a time, cycling through each connection individually and emptying buffered information to each connection. For proper application of Serial Multiconnection mode, information streams must be interpretable in 256 byte pieces, or transmissions must be limited to 256 bytes (one TCP packet).

*InterruptIR has been replaced with busyIR. Commands are now executed on a first come first serve basis and will not be interrupted by another IR command. Commands sent to a connector during transmission will return a busyIR response, and the original command will continue until completion. A command to stopir will halt any ongoing IR transmission.

*An IR command halted from a separate TCP/IP connection by stopir will cause the iTach to return a stopir response to both connections.
