Help with ‘Stable’ MX releases

Please read the announcement for the latest MX release in the forum before installing it.

We strongly advise updating to the latest version, if only for the fact that later versions offer more functionality, and may fix any bugs in an earlier release.

Upgrading

You can install a new release of MX directly over your existing version.

• Important, please read all of the release notes (in the appropriate forum announcement threads) for the builds since the version you are upgrading from.
• If you are currently running an old release of MX, you might want to check Updating MX to new version page, as that has some advice about whether it is best to upgrade in multiple steps.
• If you are upgrading from a previous version of the legacy Cumulus 1, then you might want to read Migrating from Cumulus 1 to MX page; and if you need more justification read Compare legacy Cumulus and MX page

Note by Steve Loft: you may find that anti-virus software flag a new release of Cumulus as a ‘threat’, 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.

If you need any help with Cumulus MX, please first consult, in this Wiki, the Category:Cumulus MX page for pointers to articles that may help. If you cannot answer your questions from those links, then use the correct MX support forum to see if others have answers.

Current MX Developed from

Cumulus 3 (MX) software was developed as a beta with limited functionality by Steve Loft.

• Steve Loft previously developed Cumulus 2 (where he tested using the C# language, now used for MX)
• Steve Loft created the original Cumulus software (now known as legacy cumulus 1) just for his use, before making it generally available, he then developed it over the next decade to include requirements suggested by thousands of users.
• Steve Loft, the author of Cumulus/Cumulus MX has since fully retired, and stopped providing support, or updates, to Cumulus 1 or Cumulus MX software.

Steve's final beta MX

You can download below the final beta release as made available by Steve Loft, and also his subsequent final source code.

If you are able to understand his source code (linked below), and compare it to the latest source code (linked above), you can appreciate the transformation that has taken place in recent years.

• Cumulus MX v3.0.0 beta 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).
• subsequent updated Cumulus MX Source Code from Steve Loft. He made the following comments, as he handed the project over to "the community":
  • This version of the code is post b3043 as it includes some changes that Steve had made, but not yet released.
  • 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.

Legacy releases

See downloads page for full details.

Cumulus 1

The installer for Cumulus 1 is available here *Cumulus 1099 installer.

• Cumulus 1.9.4 build 1099.2 patch Patched version of Cumulus.exe, allows date entries on NOAA reports and Snow Index up to the year 2030 (updated 28 Jan 2020). Note this is not the full installation version just a patched .exe.

Special Variants

• 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: These Cumulus 1.9.4 variants 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 and 1.9.4 variants migrate to Cumulus MX, which has ongoing support by mcrossley.
