No description provided.

The https://github.com/mixxxdj/mixxx/blob/2.5/packaging/debian/changelog update is missing. This is unfortunatly a manual process to sync back the automatically generated debian changelog of the prvious release. Can you add:

mixxx (2.5.4-1~jammy) jammy; urgency=medium

  * Build of 2.5.4

Updated - I have also added the 2.5.5 record, tho I am not sure this was expected yet and where should the date (and time) be taken from

[daschuer]

I did a brief Smoke test on my productive Ubuntu Noble. And I can confirm it works.
There is an issue with the dead transifex link
https://www.transifex.com/projects/p/mixxxdj/
this needs to become
https://explore.transifex.com/mixxx-dj-software/mixxxdj/
The manual is shown as:

I think we need to remove the patch version ".0"

[daschuer]

The online manual is also still outdated:

Is this updated with the actual tag? This seems to be broken since 2.5.3

[acolombier]

Is this updated with the actual tag? This seems to be broken since 2.5.3

Yeah, this should get fixed when we merge with the tag fix

There is an issue with the dead transifex link

Where does this need to be updated?

[daschuer]

The windows installer works as well in my Win 10 virtual Box.

[daschuer]

We need probably check every occurrences of the old Transifex link in our repository

[daschuer]

Who can do a real windows 11 and macOS smoke test?

[tuulikauri]

real windows 11

I gave it a spin! Looks good to me.

Windows 11 x64 25H2

The artifact naming has changed. Not a big deal and maybe intentional with the shift to msi instead of zip; I presume the *.msi is the only Windows installer and so the one to use for x64. Are multiple Windows builds no longer required?
Used to have: Windows x64 Installer
Now: mixxx-2.5.4-80-g4a10a98363-amd64.msi
This is a little confusing since I'm usually looking for Windows and x64 or 64 bit. It's nicer to have the version and build in the installer name, I used to try to remember to immediately rename the various Windows Installer.zip files to add a description such as Windows Installer - mixxx - abletonLink PR testing.zip

• Running the installer with 2.5.4-xxxx installed (whichever test build I last had installed from an installer, it said it was from January...) it requests User Account Control permission and then seems to complete successfully. Git Version: 2.5.4-80-g4a10a98363 (HEAD)
• Audio works on ASIO. I didnt test any other audio settings.
• Plays, stops, beatjumps, loops, volume, filters, EQ, sync tempo leader/follower all seem to be working on two decks
• I didnt test the library functions other than dragging a track in.
• I didnt test anything else... samplers, auto-DJ, broadcast, playlists/crates, analysis, beatgrids, etc
• My Traktor Kontrol S2 mk1 works in HID mode.

When I exit mixxx with a deck playing on loop and the About Mixxx properties window open it prompts "Mixxx is playing, are you sure you want to exit?" and then closes the main window, but keeps playing until I close the About window 🫠 With the properties window open I get a 2nd prompt "properties window is open. Disgard changes and exit?" and then it fully quits properly as expected. I tested on 2.7 alpha builds and it also happens; it's not a serious issue and doesn't seem to be a newly introduced bug. I can search if this is reported already and submit it as a bug.

Z1 mk1 HID?

Z1 mk1 HID script isnt working; but I think it's a computer issue. I don't usually use my Z1 controller with Mixxx, just hooked it up to test on my test computer. The Z1 controller works on 2.7-alpha builds on a different computer; but not on this computer with this build; and not on this computer with 2.7-alpha build. It seems to have the same driver version (4.2.1) on both computers. It is a dual mode HID/Midi controller so maybe that has something to do with it. On both computers it is generating MIDI messages (I can see them in MIDI-Ox), which work if I map the MIDI Controller device to a MIDI script (X1 script) on this computer.

Mapping that isn't working: From C:\Program Files\Mixxx\controllers folder:
Traktor Kontrol Z1.hid.xml
Traktor-Kontrol-Z1-scripts.js
Error message from popup:

Uncaught exception: file:///C:/Program Files/Mixxx/controllers/Traktor-Kontrol-Z1-scripts.js:128:

[JoergAtGithub]

The mentioned line in the Z1 script was changed since 2.5.4. It looks like you found a real 2.5.5 regression: #14451

[tuulikauri]

Ah, ok. I'll pull the script from before it was last changed and test it tomorrow. If the old one works, maybe we can put off this script update until 2.6? Or if there's a quick patch to be done, I can test a revised script too.

[djantti]

Hmm, that is strange. I just tested the 2.5.5 release PR Flatpak with my Z1 and it works without any issues.

[JoergAtGithub]

Flatpack has a newer Qt version - correct? It might depend on this.

[djantti]

Yeah, Flatpak uses Qt 6.10.2. There's a Qt 6.9 based runtime available too, but anything older than that is deprecated.

[djantti]

I installed the 2.5.5 PR deb package in a Ubuntu 22.04 container with Qt 6.2.4. No issues, the Z1 is working fine there too.

This mapping change seems to be introducing a new feature (fader calibration support). Shall we revert this PR in 2.5 to unlock the long time due release and fix forward in 2.6 which should follow up in weeks?

[tuulikauri]

I completed further testing; the Z1 mapping is the issue, not my computer. Further discussion/logs/etc here: #16172

[dheeraj23195]

macOS Smoke test performed.
Device: Macbook Air M1
OS version: Version 26.3.1 (25D2128) - Tahoe
I downloaded the MacOS Artifact from ths PR and performed the following tests:
Launched the application and found these two dialog popups (attached below), Improted tracks, loaded them to deck 1 and 2, and testing normal DJ capabilities like sync, crossfader, tempo adjustment, playback, seeking, EQ knobs etc. and searching for tracks in library.
mixxx.log checked – no critical errors observed.

[daschuer]

What are the pending issue?

• Transifex link
• Manual version number

Anything else?

[tuulikauri]

Anything else?

I think the Z1 script needs to be reverted while we troubleshoot why it's not working on Windows; but I leave it up to the core team to decide (it seems to be reproducible beyond just my computer; and the old script is working on my computer)

[acolombier]

Manual update waiting for review here

[tuulikauri]

The traktor Z1 script is fixed, tested, reviewed, and merged into 2.5 here #16182

[acolombier]

... and rebased!
Manual is updated and Transiflex was rebased too so we are ready to go.

[tuulikauri]

... and rebased!

Nice. Uh I dont see the script file in the changed files list here though? This might just be github newbiness...

[acolombier]

I dont see the script file in the changed files list here though?

Yes, it is already in 2.5

[acolombier]

@daschuer are we good to go?

[daschuer]

Yes, go ahead.

[acolombier]

Great, I will get the release out later
