Where are the downloads?

A couple of days ago I noticed that the KLog files, hosted in Savannah.nongnu.org were not existing anymore…

I am in contact with the Savannah admins to try to recover the repositories but just while the repositories are back or the final decision is to move to another place, the latest release is here:

https://github.com/ea4k/klog/releases/tag/1.4.7

Sorry for the inconvenience.

I am releasing today KLog 1.4.6.

It is a very special release, even if not too big, because the work has not been done by EA4K 🙂

KLog 1.4.6 changes have been coded by EA5WA who is working hard to understand how KLog is done and sending many improvements, comments, testing support to the users and during the last weeks also code! (Congratulations!)

This is the Changelog:

 January 2021 - 1.4.6
 - Bugfix: Improved the way the QSOs come from WSJT-X. (EA5WA)

We have also changed QRZ to Callsign, something that has been requested by users 🙂

KLog is in GitHub

From time to time some people ask me to push my code to GitHub.

I must admit that I am confortable having KLog in the Savannah SVN. It works without any error, not a single problem since I started to use it many years ago, I also have some automations built at home, in my development environment… I though that it made no sense to migrate to GitHub.

Some days ago I decided to move my code to GitHub, I will probably keep Savannah and GitHub repositories until (hopefully) I finally get the same feeling with GitHub than Savannah.

I am doing this with the hope that some of you will be contributing to KLog easily if it is in GitHub and maybe KLog improves 🙂

If KLog development is mainly mine, it makes no sense to move to GitHub.

Anyway, you can find two repositories:

https://github.com/ea4k/klog This repository hosts the code of KLog.

https://github.com/ea4k/klog-data This repository hosts files that are useful for KLog users or developers.

I hope this changes are useful for KLog!

KLog wiki

Many times, many people have asked for a manual, documentation, guide or similar.

A document explaining how to do something in particular or define some feature.

I admit, I prefer to code than to document but the manual could not wait any longer.

I have installed a Dokuwiki instance so we (yes, not only me, you also can support) write a manual for KLog.

You can find the manual in the KLog wiki.

If you want to contribute, register with your callsign and send me an email so I can change your profile to the editor profile… yes, it is not done automatically but I prefer to go this way to have the wiki full of spam in some days.

I will work on the wiki, trying to explain how to use KLog and I will also try to not releasing a new feature that is not explained I the Wiki.
