Upgrading from R15.1

December 5th, 2016

Isode provides full support for Major and Minor releases of Isode’s server products, management tools and APIs for five years from the date of release. As of the end of November 2016, R15.1 came off of full support.

Release Notes for fully supported releases (currently R15.2, R16.0, R16.2 and R16.3) provide instructions for upgrading from R15.1. If you would like Isode advice on your upgrade and you have a current Isode support contract, then please get in touch and we’ll be happy to provide assistance with this and answer any questions you may have relating to R15.1 and support.

You can contact us either by emailing the support department or by using the Isode Self-Service Portal.

Reporting from the Nordic HF Conference – New HF ALE (Automatic Link Establishment)

August 18th, 2016

Isode CEO, Steve Kille, is attending, presenting at and reporting from the Nordic HF Conference (HF 16) on the island of Faro, Sweden.

Professor Eric Johnson led Wednesday morning’s session with an excellent presentation on new ALE work, called 4G ALE or Wideband ALE (Wideband ALE – The next generation of HF). This was followed by a presentation by Harris on preliminary measurements. Eric noted the importance of work in this area to support new WBHF and to reduce setup times. This is key technology for HF.

This work is being done by US DoD, with support from key US vendors (in particular Harris and Rockwell Collins). I asked when details of this work might be made available, and the answer was “not clear” and perhaps end of next year. This will likely be at the point when the work is published as a US Mil Spec. Then it will be shared with the rest of the world, and presented as a fait accompli for NATO to standardise. This may be a good way to achieve a solid standard. However, it feels to be locking out non-US involvement and giving unfair competitive advantage to US vendors.

Reporting from the Nordic HF Conference – Wide Band HF

August 17th, 2016

Isode CEO, Steve Kille, is attending, presenting at and reporting from the Nordic HF Conference (HF 16) on the island of Faro, Sweden.

WBHF is a key new development, and there were two good papers at Nordic HF on measurements during Session 2 on Monday.

Vivianne Jodalen, Terje Mikal Mjelde and William M. Batts reported on measurements made in the arctic (Wideband HF in the Arctic) and measurements made across the Atlantic (Performance of a transatlantic long-haul wideband HF system).

The good news is that a range of successful measurements were made in over-the-air environments. The practical results suggest that 6kHz channels (wider than 3 kHz narrowband) can often be achieved, but it was often not possible to realise the maximum of 24kHz. Throughput was generally quite a bit less than the “top end”.

While this is useful information and gives performance much better than narrow band, it is a long way short of the top end 120 kbps. I think there is a real risk that people have been over-sold WBHF and will be disappointed with the reality. This would be a pity, as it offers useful improvements.

Swift 4.0 (Beta): What’s new

August 3rd, 2016

Those of you keeping an eye on the Swift or Isode Twitter accounts will have noticed that a beta release of the new Swift 4.0 is now available for download from the Swift website .

Swift 4.0 includes a number of important functional changes compared to Swift 3.0 as well as a significant change to the look and feel of the product.

The main changes are listed in the changelog but there are two big changes that you’ll notice immediately on launching this Swift beta.

Better Chat Monitoring

Swift already makes it very easy to monitor events in multiple chat rooms through the use of keyword highlighting rules. In response to requests from a number of users we’ve supplemented this with the addition of a “trellis” layout option, allowing multiple chats and rooms to be tiled instead of being exclusively displayed as tabs within a single window.

This new option (Change Layout from the View menu) allows the user to define the number and arrangement of tiles to be displayed simultaneously and then move chats or rooms into an appropriate position. The trellis layout option and the existing tabbed layout option can be flexibly combined.

New Chat Design

We’ve introduced a new, cleaner chat design which we believe will enable users (especially in MUC rooms) to keep better track of their own contributions to conversations allows for better display of message receipts and better indication of unread messages.

The Swift 4.0 beta is available for Windows, MAC OS X, Ubuntu & Debian Linux. Please email (swift@swift.im) or tweet @swift_im any feedback you have to help us further improve Swift.
