MC V17 Early Access PREVIEW

(1/3) > >>

Mathias (Author):
Version 17 is not ready for stable release anytime soon, But it already has a lot of new things that need testing

Not everything added to v17 might be included in the final release.
v17 contain many MAJOR rewrites and new addition.


* File Tags/Labels and comments system
* Folder Specific settings
* New Keyboard customization system
* Total rewrite of List/Grid UI component used for File List view, FolderTree view, Most List/Grid UI componets. Without this rewrite all the 3 items above would not be possible
* MultiFileViewer can now show CSV/Parquet files as data in a grid. and if it is CSV it can be edited and modified and saved backed
* Some extension in MC can now be developed using .Net/C#
* Checksum extension now support Blake3 checksum algorithm
This is a early preview. Since it is a early preview it is time locked. and will stop to work after sep-30. (but a new updated version will be out.. )
However it will not be possible to auto update this version until in reached beta. there might be more 16.x releases with fixes before this is officially out

Since this is early preview. NOW is the time to come with feedback you want something to change. How a features with file tags or folder specific settings works or something like that.

Since this preview is developed separately from v16.x, When a new preview is released, it might not have all the fixes or addition that 16.x has. Right not V17 Preview has everything 16.2 build 3205 has. (I think)

It starts then hangs forever. I manually set log level to debug but didn't see any suspicious. At first start MC asked to choose the language and Look'n'Feel. Now it just hangs every launch. Task Manager shows 0% CPU. No antivirus alerts.

I don’t really like that the keyboard shortcuts no longer work. It feels a bit too “early” to me.

And I couldn’t notice any change in the scrolling behavior, except that it’s harder to follow the scrolling with your eyes. How about smooth scrolling?

Which are the new modules that I need to remove from the modules.xml file to get rid of the following error message?

“1 Extension/Modules was invalid and could not be loaded.
This can happen after a failed upgrade or with external modules that need to be updated separately.”

Its called early preview for a reason.. What keyboard shortcut does not work anymore ? Can you please be more specific so I can replicate that

Whats wrong with scrolling?, I see no difference from before.. Smooth scrolling will probably noy be added since that would slow down and eat lots and lots of cpu (Refresh everything, move 1 px down  redraw everything and so on.. ..)

In App Log you see what module failed to load..  what module failed ? they should all load in the preview.  missmatch of version normally only happens if you upgrade and some modules failed to upgrade or something.
