Final Cumulus 1 version

The final production version of Cumulus 1 (running in Windows for all supported weather stations) is not being supported any more. Existing Cumulus 1 users can update to this final stable installation version, download it here.

Having updated to that version, there is a patch available here which simply replaces the file "Cumulus.exe" from above version. Whilst you can type any year you like into selection boxes on view month, view year, view period, and view NOAA report, this patch allows you to select years up to 2030 from a drop down in the relevant screen box.

The 1.9.4 helpfile can be viewed at Cumulus Top Weather Sites and downloaded (for viewing using Windows Help) at Cumulus.chm. Other resources are listed at Software#Resources.

Earlier Versions

Steve Loft, as well as updating the support forum with announcements about his releases for Cumulus 1, maintained an abbreviated summary in changes.txt, find it at File:Changes.zip. It covers releases back to version 1.0, the first release on 27 January 2004, although the documentation for a small range within that was lost.

For the way dayfile.txt changed between versions, see that link.

Note about this article

When Steve Loft was about to retire from involvement with Cumulus, he wanted to close his web server. His server (sandaysoft.com) had hosted the wiki, the support forum, and some of the downloads were at http://sandaysoft.com/downloads. The other downloads (used mostly for beta and special releases) were at http://www.nybbles.co.uk/downloads which was also closed.

In October 2018, Ken True ("saratogaWX") offered to host the Wiki on his site. The Cumulus 1 software files were downloaded from the links mentioned above, and then added to this "Downloads" page by Ken as part of the migration of the Wiki.

The next month (November 2018), Steve Loft sought a new host for the support forum, as next part of closing his web server. The Cumulus MX beta that Steve Loft was writing and hosting on his web server was available as a download within the support forum. When Niall Hosiene ("Freddie") took over hosting of the forum, all the forum contents, including attached files, were moved to his server.

It appears (as the main page suggests "We've added download links for Cumulus V1 and Cumulus MX in the new Software/Downloads page ") there was a bit of conflict between Downloads page and Software page.

• Ken True created new "Downloads" section in this Wiki referenced from other pages; to this were added the Cumulus 1 final version software download, the help file download and the Cumulus 1 special downloads for Instromet.
• Mark Crossley on taking over Cumulus MX development created a new Wiki page just for links to his GitHub pages where the source and distributions for MX are now held (instead of as attachments to forum posts).
• Niall Hosiene edited the new Software page to make it one destination for both MX and Cumulus 1 software, he overlooked that other pages in this Wiki were linking to the original Downloads page. He was so keen to promote MX, his edit downgraded Cumulus 1 to legacy and the links to the various Cumulus 1 downloads were consequently made harder to spot.

Subsequently:

1. this wiki page has been resurrected for Cumulus 1
2. the Software page has been improved by Ken True, and now has better links to Cumulus 1 and the patch.
