Changes contained in version 3.0.0 (12/02/2015)

Note: Downgrading to firmware prior to v3.0.0 is not supported. Firmware updates are only supported via HTTP once a device is upgraded to v3.0.0. We are working to re-enable firmware update via HTTPS in a future release. 

* Fixed SNMP requests with long OIDs causing reboots. 
* Fixed SNMP GETNEXTs on invalid OIDs wrapping around to beginning of the MIB and causing an infinite loop in some SNMP managers. 
* Improved validation of various numeric and IP-address entry fields. 
* Removed support for deprecated SSLv3 protocol, for security reasons. Only TLS v1.2 is supported. 
* Removed support for 512-bit SSL/TLS certificates. 
* Server certificates have been upgraded to 2048-bit. 
* Added support for mail servers that use STARTTLS, such as Office 365. 
* Added support for the new Analog to Digital Converter (A2D), which will replace the CCAT interface (WD15/100; GU only). 
* Special characters '-', '!', and '~' are now permitted in SNMP community strings. 
* New web interface, including a JSON-based web API. 
* Added automatic Daylight-Saving Time (DST) adjustments. 
* Added support for SNMPv3. 
* Added support for IPv6. 
* New, more flexible and configurable alarm system: 
o Alarm triggers now have individual delays for both trip and clear. 
o Delays and Repeats can be anywhere from 0-14400 seconds (14400 seconds = 240 minutes, or 4 hours). 
o User can define up to 8 Òvalid timeÓ ranges, and set individual alarms to trip (or not trip) only within or outside of those times. 
o User can now define up to 32 alarm ÒactionsÓ, each with individually-settable delayed and repeating actions, and assign any of those actions to any alarm trigger. 
o Alarm triggers can be set to be either ÒAlarmÓ or ÒWarningÓ. 
o An alarm or warning can be made to ÒlatchÓ, requiring the user to manually log in to acknowledge and clear the event. 
* Upgraded to the new Geist web interface and web API. 
* Added IPv6 support. 
* Added SNMPv3 support. 
* Added a new, more configurable alarm system. 
* Note: Existing alarms will have their repeat timer options reset as part of the upgrade to v3.0.0. 
* Due to this change in the alarm-system behavior, be aware that any alarms which currently have Òrepeat every ÔxÕ minutesÓ set in your current v1.x.x firmware will have their ÒrepeatÓ settings reset to Ò0Ó.Ê You will need to go back into the alarm settings after the update and manually re-enable repeats on the alarm actions after updating.Ê Also, note that all delay and repeat timers are now given in seconds, not minutes; if you previously had a 30-minute repeat, for example, be sure to reprogram it as Ò1800Ó, not Ò30Ó). 
* If your unit is an ITWatchdogs-branded device with a firmware version prior to v1.6.0, you will need to install the v1.6.0 firmware before updating it to v3.0.0. 
* Watchdog 15 v1.6.0 
* Watchdog 100 v1.6.0 
* Firmware v3.0.0 is not compatible with Watchdog Console Aggregator.Ê The 3.0.0 firmware does not implement the deprecated XML-based API which Console used and Console is not able to use the newer JSON-based API.Ê Console Aggregator itself has been discontinued in favor of RackNet Node Manager (existing Console owners may be eligible for a discounted upgrade to Racknet-NM; contact Geist sales for more information).
