                            Upgrades for Jana2020 are available several times a year. In between these upgrades, ongoing development of the program occurs, resulting in patches that are released very frequently, sometimes even several times a week.
To obtain the correct patch, you must first install the latest version of the program from the Downloads section on the program's website. After launching the program, you can download the patch by clicking the "Download patch" button in the About section of Jana2020. This will download the file jana2020-patch.exe, which can be found in the directory where the program is installed.
Next, you’ll need to complete a few manual steps: first, close the program and rename jana2020-patch.exe to jana2020.exe. Then, reopen the program and check in the About section of Jana2020 using the "Detailed info" button to confirm that you are indeed using the correct patch.

                                        Dear Michal,
I am running the latest version available for download, #1.3.61. It is not possible to patch it since it does not correspond to the 'newest version 2.1'. Where can I obtain the installation files of version 2.1?
Thank you.

                                        Dear Jana-developers team,
Recently, I found a publication devoted to the better evaluation of the Theta shift for the case of Debye-Scherrer geometry combined with the flat 2D detector.
(Please see the article doi.org/10.1107/S1600576722011360)
I would love to hear your thoughts on this. Seemingly, such a setup is fairly common (I see it often in synchrotron setups) - and, maybe, you might consider adding a similar equation / function in further Jana updates?
Do you think the existing Theta shift tools (zero shift / sycos / sysin) can still effectively describe the shifts observed in such a setup (Debye-Scherrer + 2D detector)? 
Perhaps you could recommend which option among the existing ones would be the best choice?
I would deeply appreciate your response.
Thank you very much for your time!
Sincerely,
Mariam

When I attempt to download the 2020 version I am met with a 404 not found error.
Kind regards,
Hunter

                                        Instead of left-clicking on the download link, right-click on the link and 'save link as' to save the 'Jana2020Inst.msi'.

                                        Hello Hunter, 
I was not able to replicate the issue you reported. When I click, I receive a security warning, and then I can download the file without any problems. We were fixing some issues yesterday, so it is possible you encountered a glitch during that time. Please let me know if the problem persists. 
Best wishes, 
Michal

                                        Hi, I can confirm that I cannot download 2.1 - I get a cryptic red "The version field is required" error, though I do not see a "version field" anywhere.

                            I would like to perform multipole refinements (Hansen-Coppens formalism) in Jana2020. In the Jana2006 cookbook, there is one example of this (Example 10.2 on oxalic acid), but I can't find it in the Jana2020 cookbook. Do you plan to include this example (or a similar one with multipolar refinements) any time soon? I am also interested in how to convert files from xd2024 multipolar refinements into the jana2020 format. Thanks in advance!

                                        HI Sofie, 
The example is in an unfinished state. This is a good impulse to finish it. Please have a look at the cookbook later on - I would estimate I can finish it within the next two weeks. I will also address your question regarding XD2024 files. Multipole refinement in Jana2020 is used by several users, so it should be an easy job. 
Best wishes, 
Michal

                                         Just additional information: The import from XD2024 has been tested, and it seems to be working correctly. However, as the way Jana2020 defines the local coordinate system is not entirely identical to XD2024, you should check it carefully. Please report if you have any problems.

                                        Hi Michal and Vaclav, 
Thank you for your quick response! Great to hear that the oxalic acid example will be available in the Jana2024 cookbook soon. That will be of a great help!
I cannot make the import from xd2024 work properly, unfortunately. It works before I start performing my xd refinements (on the files that emerges after solving the structure and then performing xdini2024), but not on my refined models. I have tried on some older xd projects as well (from xd2016 though) and experience the same issues. I either get a Fortran run time error (forrtl: severe (64): input conversion error, unit -5, File internal Formatted Read) or an "atom 0.0000 present only in parameter file" error. In the last case, it seems to not recognize the first atom name in the input file, and instead reads its first parameter as an atom name. 
I am currently trying to figure out why the conversion works only on the "simple" xd files before modelling etc.
Best, 
Sofie

                            Yes! Starting with version 2.1, Jana2020 can be installed in the Program Files. Older versions created temporary files directly in the installation directory, meaning that Jana2020 installed in Program Files needed to be run by an Administrator. However, with version 2.1, temporary files are stored in the %APPDATA% directory, allowing Jana2020 installed in Program Files to be run by a normal user.
