In 20190822-2e2a2f9739-win_x86-devprev, the new function structure.GetSymCount is missing. (There's no new "symmetry" function that I can find, either.)

The help for band.AddBetweenSegments doesn't show the new chain identifier. Attempting to call the function with a chain identifier results in an error stating that 2 to 4 arguments are valid.

When I opened the DevPrev client, it didn't update the version.

Should we use "experimental" or something else instead ?

No, it should be devprev. What platform is this on?

I'm on Windows, and I finally noticed that the build id is 20190822-2e2a2f9739-win_x86-devprev, so 22 August 2019. This was definitely an update, so maybe the August build was pushed instead of the new October version.

I just tried starting a new client and paying a little more attention. There was no update, and the build id remains at 20190822-2e2a2f9739-win_x86-devprev. The function structure.GetSymCount is still absent.

There's a new hotfix to devprev. The latest version has structure.GetSymCount in it, so that's progress.

More progress. The function structure.GetSymCount works, and so does the new version of band.AddBetweenSegments with a fifth parameter.

On trimer puzzle 1752, GetSymCount returns 2.

The following code bands segment 2 on the main chain to segment 2 on each of the symmetric chains, specifically atom 5, the beta carbon of each.

print ( "symmetric chains = " .. structure.GetSymCount () )

for ii = 1, structure.GetSymCount () do
   band.AddBetweenSegments ( 2, 2, 5, 5, ii )
end

There is no update for Mac
(OS 10.8.5)

Version.database: 5 dec 2018

Windows is at 20191029-32048a6a12-win_x86-devprev.

(For those just tuning in, see devprev on the wiki for how to get the developer preview release.)

The version is found as "Build ID" under General Options, control + T or the equivalent. The same dialog shows the "Update Group" the client is using.

The build id also appears in log.txt, but it can be hard to find. It looks something like this:

buildid: 20191029-32048a6a12-win_x86-devprev

The symmetry functions seem to be working on Windows devprev, so I'm closing this feedback.
