SRBase: don't use mfakto beta3
Someone is using mfakto0.16 beta3 somehow but we have not setup the app yet.

The app is not using multicore and making some results invalid due illegal checksums.

Pls stop running such apps which they are not supported yet.

SRBase: SRBase - 11 years review
The project has passed the 11th year...

Compared with last years the following process was made:

2014-2015 - 1 base proven, 314 bases unstarted
2015-2016 - 5 bases proven, 297 bases unstarted
2016-2017 - 5 bases proven, 282 bases unstarted
2017-2018 - 1 base proven, 264 bases unstarted
2018-2019 - 6 bases proven, 218 bases unstarted
2019-2020 - 4 bases proven, 120 bases unstarted
2020-2021 - 3 bases proven, 101 bases unstarted
2021-2022 - 0 bases proven, 97 bases unstarted
2022-2023 - 3 bases proven, 69 bases unstarted
2023-2024 - 4 bases proven, 69 bases unstarted
2024-2025 - 3 bases proven, 28 bases unstarted
in total - 35 bases proven, 28 bases unstarted

With the new pythonscript, available for windows, linux is planned later, we have decreased unstarted bases by a lot on manual testing.

There were many improvements like less RAM consumption and memory usage, and better distribution of workspaces among the workers.

Thx to all participated users who made this possible!

All 2025 goals are done earlier and some 2026 goals were already started.

Unfortunately, all TF applications need to be renewed, which is why all results from the GIMPs server will be rejected after the 31st except mfakto apps earlier.
