‘Stable’ releases

If you need any help with Cumulus, Please first use this Wiki FAQ then use the forum.

The author of Cumulus/Cumulus MX has retired and will not be providing support or updates to this software. However the source code has been released and community effort updates to Cumulus MX (only) are now being provided by mcrossley.

Cumulus MX

Current Release

Latest build is...

• Cumulus MX v3.4.6 build 3070, 23-March-2020 Cumulus MX, a cross platform version of Cumulus which runs on Windows, Linux (including the Raspberry Pi) and Mac OS X. (M Crossley update)
• Cumulus MX Current Source Code This code base is updated for all releases after b3043.

Historic

This release and source code are the last offerings from Steve Loft before he handed the project over to "the community".

• Cumulus MX v3.0.0 build 3043, 20-Jan-2017 Cumulus MX, a cross platform version of Cumulus which runs on Windows, Linux (including the Raspberry Pi) and Mac OS X (Steve Loft - final release).
• Cumulus MX Source Code The original source code from Steve Loft. Offered completely without support in the hope that it might be useful. The code is very badly structured due to the 'Frankenstein' way it was cobbled together from various places. Some of it is a machine translation of parts of Cumulus 1. This version of the code is post b3043.

Legacy releases

Cumulus 1

We do not have copies of old versions of Cumulus, so please do not ask for them. Only the current version is supported. If you obtain copies of older versions of Cumulus from elsewhere (e.g. web archives) please do not ask for help with them. We strongly advise against using an old unsupported version, if only for the fact that it is likely to have bugs which have been fixed in later releases.

Note that if you use certain anti-virus software -- in particular Avast or Symantec -- you may find that they flag the Cumulus installer, or Cumulus itself, as a ‘threat’ and block it, for a few days or weeks after a new version has been released, even though it does not actually contain a virus of any kind. This is due to a system they call ‘reputation’ where they automatically block any versions of software which have recently been released. You may want to consider complaining to the provider of your anti-virus software about this ridiculous system, or better still, use some better anti-virus software.

Please read the announcement for the latest release in the forum before installing it. If you are upgrading from a previous version of Cumulus, please read all of the release notes (in the announcement threads) for the builds since the version you are upgrading from.

• Cumulus 1.9.4 setup Cumulus setup file -- LAST stable version -- build 1099 - 14-Nov-2014
  • Cumulus 1.9.4 build 1099 patch Patched version of Cumulus.exe, allows date entries on NOAA reports and Snow Index up to the year 2030 (updated 28 Jan 2020)
  • Cumulus 1.9.4 build 1100 setup Use ONLY if you are an Instromet user, and your logger operates at 115200 baud, you should use build 1100
  • Cumulus 1.9.4 build 1101 setup Use ONLY if you are an Instromet user, and your logger operates at 19200 baud, you should use build 1101
  • NOTE: Cumulus 1.9.4 will not have any updates in the future. In 2020, some of the menu items with year choices will not display years beyond 2020. This will happen on manual generation of NOAA-style reports. The NOAA reports should continue to be automatically generated, but the capability to create them on-demand will only work through 2020. It is STRONGLY RECOMMENDED that users of Cumulus 1.9.4 migrate to Cumulus MX, which has ongoing support by mcrossley.
