1. PTP Option: Fixed mishandling of packet sequence numbers when packets are dropped.
2. Fixed bug where password is displayed when upgrading firmware using the Web Interface.
3. Fixed bug that prevents you from upgrading firmware using the Web Interface and the
"Upgrade From Local File" option. Because of this flaw in your current version
you must upgrade using the Web Interface and the "Upgrade From FTP Server" option, or
by using the command line interface.
4. Fixed bug introduced with change to NTP distribution 4.2.6p3 where ntpd would terminate if user did not configure network settings.
RECOMMENDATION: Upgrade if you have the PTP Option or use the Web Interface.
NOTE: A major change occurred at version 2.60. If you are upgrading and the current version in your unit is prior to that, then please read the
information on version 2.60.
NOTE: If you are looking for the IPv6-capable kernel please see version 2.60 information.

1. Updated NTP distribution version to 4.2.6p3 which solves the vulnerability below (item #5) and also
improves timing jitter performance.
2. Added version 2 for PTP/IEEE-1588. This only pertains to those who have purchased
the PTP Option.
3. Fixed network domain name bug for domains with more than one '.' in them.
4. Fixed rare Secure Shell permissions bug.
5. Workaround for ntpq/ntpdc remote query vulnerability. Did this even though
the updated NTP distribution should solve the problem.
RECOMMENDATION: Upgrade if one of the above items is important to you.

| 5.50 |
1. Added capability for PTP/IEEE-1588 Option that allows setting of multicast time-to-live (ttl) variable.
2. Added capability to edit and view the Domain Name Server (DNS) via the front-panel keypad/display.
3. Fixed a bug related to erroneous SNMP FaultStatus2 traps.
4. Fixed a bug in the "gpsrefpos" command which inhibited showing reference position
in "unknown" and "dynamic" modes.
5. Fixed a bug in the SNMP MIB related to the plug-in options.
6. Added Web Interface (HTTPS) for monitoring status of all functions and for upgrading software. This
new capability is only for units with Software Number 6010-0044-000. The Web Interface is disabled for units with
Software Number 6010-0042-000 (because these are older units and the required hardware is not available).
RECOMMENDATION: Upgrade if one of the above items is important to you.

Fixed a bug related to the gsysuser login. If you are having trouble logging in to your
unit then upgrading your software will not correct the problem. Please see this Field Service Bulletin.
RECOMMENDATION: No need to upgrade.
|
| 5.10 |
New option added to the product line: Precision Time Protocol (PTP/IEEE-1588).
RECOMMENDATION: No need to upgrade.
|
| 5.00 |
Added software support for new features: Telecom Clock Output Module and Dual Power Supplies.
RECOMMENDATION: No need to upgrade.

1. Modified the start-up sequence to eliminate the need for operator intervention in order
to show the time on the display. Now the unit will go to the time display 30 seconds after
the startup sequence has finished.
2. Added additional format selections to the Serial Time Output Option.
3. Changed TFOM value to be in the range of 9-3 (was 9-4). A TFOM of 3 indicates
synchronization accuracy to within 100 nanoseconds.
4. Added CRC checking on the time information going from the GPS Subsystem to the Linux Subsystem.
This will further bulletproof the timekeeping ability of the product and prevent any possible time jumps
in the rare case (seen only once) of a hardware glitch on the circuit board.
RECOMMENDATION: Upgrade if you would like the features listed in #2 or #4.

| 3.02 |
1. To enhance SSH security, the default was changed from accepting versions 1 and 2 protocol connections
to only accepting version 2 protocol connection. Version 1 is considered insecure.
2. Fixed a bug wherein the NTP Server continued to serve time for too long after loss-of-lock to GPS synchronization signal.
RECOMMENDATION: Please upgrade.

| 3.01 |
1. Fixed a bug related to the AM/PM local time display.
2. Added 0.1 meter resolution capability to the console "setgpsrefpos" script.
RECOMMENDATION: Upgrade if you use local time 12-hour mode for your display.

| 3.00 |
1. Added ability to change TFOM level at which alarm occurs.
2. Added ability to set optional Serial Time Output format via front-panel keypad/display.
3. Added ability to mask off certain alarms - the Antenna Fault and the
Signal Loss Fault.
4. Added more selections for the optional Programmable TTL Output.
5. Added alternative Time Display that shows the time with Day-Of-Year as: DOY:HH:MM:SS.
6. Fixed a bug related to unprivileged user in cntpstat/gntpstat reporting.
RECOMMENDATION: Upgrade if you care about one of the items above.

use the Daylight Savings Time (DST) feature.

Major upgrade with updated versions of all applications, utilities and shared
libraries typically installed in an embedded Linux-based system. Please click
here
for IMPORTANT information.
RECOMMENDATION: Please upgrade.
NOTE: This software release is IPv6-capable. IPv6 is in the experimental stage but some
of our customers want it now. In order to enable IPv6 operation you
must perform a second upgrade operation to replace your IPV4-only kernel. If you want IPv6 operation then:
