• New Bluetooth mass lock and unlock commands
• Support for new product line: Aquarius

Many system performance and stability enhancements are also included, as well as a number of bug fixes.

dig v2.0 includes an upgrade of the bootloader so there is a small chance of serious problems if the upgrade process is interrupted for any reason (although significant precautions have been taken to minimise this risk). It is recommended that the upgrade only be performed when the network and power-supply are both known to be stable.

For this reason, the upgrade dialogue in the Firmware Update section of Discovery will offer the choice of whether to accept this upgrade or not. Users wishing only to upgrade to the latest dig v1.2 or dig v1.3 can, therefore, avoid dig v2.0 if desired.

• SeedLink backfill requests based on packet sequence number are no longer rejected. However, please refer to the list of known limitations under Important notices to see what happens when backfill is requested by packet sequence number.
• SeedLink backfill time increased to cover 15 minutes.
• Usable RAM size increased to 220MB for better system stability.
• System image file pre-allocation added to prevent Minimus crashing during system update (after a long run).

• The built-in copy of the FPGA firmware file has been upgraded to v3.11.

2017-03-17 : version 0.80-21461

Eight notable changes from dig v0.80-18652 to dig v0.80-21461:

• More stable and robust Bluetooth connections – GüVü version 1.3 or older might fail to communicate with this dig version, because the Bluetooth protocol has changed.
• Feature: “temperature training”.
• Feature: “power save”.
• The U-Boot bootloader associated with this dig version has been updated to v2017.03-1, to fix the intermittent Ethernet TX timeout failures.
• More stable and robust GDI connections.
• Stability and speed improvements to “System Update”.
• Send and receive timeouts for sockets now work – lightweight IP in dig has been updated to v2.0.1.
• Very many other bugs have been fixed.

2017-01-16 : version 0.80-18652

One notable change from dig v0.80-18650 to dig v0.80-18652:

• The U-Boot bootloader associated with this dig version has been updated to v2017.01-1, to fix the intermittent initialization failures of external microSD cards.

2017-01-09 : version 0.80-18651

One notable change from dig v0.80-18650 to dig v0.80-18651:

• A bug with calvals.txt link not working was fixed.

2016-12-09 : version 0.80-18650

Three notable changes from dig v0.80-18500 to dig v0.80-18650:

• Low-latency filter coefficients improved.
• A few typos, wording inconsistencies and formatting inconsistencies have been fixed in RESP files.
• The network code in the dataless SEED file is no longer hardcoded to GU.

2016-11-28 : version 0.80-18500

One notable change from dig v0.80-18480 to dig v0.80-18500:

• Prevent dig from crashing whenever users click on the button in the Data Flow web page.

2016-11-25? : version 0.80-18480

One notable change from dig v0.80-18409 to dig v0.80-18480:

• The built-in copy of the FPGA firmware file has been downgraded from v2.10 to v2.1, because FPGAs running firmware v2.10 do not lock/sync their main clock correctly.

2016-11-21 : version 0.80.18409

With dig v0.80-18409:

• Minimuses should no longer encounter the “stuck at RomBOOT” issue.
• The Minimus’ status.txt file is now sent to Seedlink clients every 5 minutes by default, via the new SeedLink SOH channel.
