New mailing list created

Some weeks ago Savannah.gnu.org decided to remove the full KLog project.

I lost some information like the mailing lists.

The main lost was not the archive, as the KLog mailing list was old but not very active but the trust I had in the savannah.gnu.org support to free software as it is not the case… anyway…

I have created a list on Groups.io for KLog.

You can find all the info here:

KLog 1.5.1 – When KLog left Savannah

The last month has been the month when KLog left Savannah after being hosted for many years.
It’s been a weird story of a possible misunderstanding, an over reaction and the ego of a Savannah admin that was not able to recover from a complain…

It was really amazing that an admin of the Savannah GNU decided to delete the full KLog project and they were not supported even for a proper leave. They removed everything, including the sources, packages, mailing lists… everything! :-\

It’s been shown that https://savannah.nongnu.org/ is not a proper partner for free software as it is not reliable and hosting your project there is a risk for its availability as it depends on an admin personal decision.

Anyway, KLog is no longer hosted in Savannah, We still don’t have a mailing list but we do have the Telegram groups.

KLog 1.5.1 fixes some bugs and removes Savannah from the repository list to GitHub where KLog is happily hosted since a couple of months.

This is the changelog.

April 2021 – 1.5.1

  • Added the GitHub repository to find new releases due to the issue with savannah.nongnu.org
  • New feature: F4 toggles the real time status (on/off).
  • Improvements on call identification management on user input.
  • Bugfix: Editing removes QTH and name (Closes issue #113)
  • Bugfix: Some complex calls (i.e. F/EA4K) were causing a crash unders some conditions.
  • Bugfix: DX Entity of some complex calls where not properly identified. (Closes issue #8).

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:


Sorry for the inconvenience.
