One wire library still in v2.3.0 - causes useless warning

[vicnevicne]

The version of the OneWire library proposed by the library manager is still v2.3.0, which causes the IDE to raise the following warning on compile :

WARNING: Category '' in library OneWire is not valid. Setting to 'Uncategorized'

This fix (and others) is included in OneWire lib v2.3.1 which was released on Dec. 6th - https://github.com/PaulStoffregen/OneWire/releases - so the IDE should link to v2.3.1 now.

I had a look at that repository, it looks like it has a proper tag, which also contains the proper version number in its library.properties file, so it should be picked up. I can't look into the server side system for errors, though.

Hi, Matthijs, and thanks for looking into this.
Do you know how the "standard" libraries are referenced in the IDE ? Is there a list of urls in a config file somewhere or is the list fetched online ? Could it be a caching issue ?
Best regards. Vicne

@vicnevicne
it seems that the library has been updated in the library manager:

maybe your PC is unable to update the library_index.json file?
(if you're on windows you can find it in %LOCALAPPDATA%/Arduino15 folder)

Hi, and thanks for helping.
That's weird : I can find the file you mention and itgets updated by the IDE, but the contents still references only 2.3.0.
Here are the steps I just did :

1. Exit IDE
2. Delete the old library version. I admit I found no procedure about how to uninsall a lib so I just delete both :
   "C:\Users\AppData\Local\Arduino15\staging\libraries\OneWire-2.3.0-github.zip"
   and :
   "C:\Users\Documents\Arduino\libraries\OneWire2.3.0"
3. Restart IDE
4. Sketch > Include library > Manage libraries > Filter on "OneW" > Click on OneWire
   (I'm just getting an "Install" button with no choice of version)
5. Click "Install"
   => Shows version 2.3.0 :

The library_index.json file has been updated (see timestamp) but only references v2.3.0 :

What is the URL the library_index.json gets downloaded from ? Could it be that a config file somewhere on my machine still points to an outdated URL or something ? Or could it be that the URL is somehow unreachable which would cause the old version to be reused ?
Best Regards. Vicne

OK. Did more tests and it seems clear now that this is due to issue #4272
The gzip file did not get updated (still dated August, see above).
After deleting it, it was re-downloaded on next use of the library manager and I was given the option to update OneWire to 2.3.1.
So I guess this issue can be marked Duplicate, but that puts more pressure towards #4272 :-)

Fixed by #4361

I recently released OneWire 2.3.2, with support for Arduino Zero & Arduino 101 (Intel Curie).

Can anyone confirm if they're seeing the latest 2.3.2 release in the library manager?

[vicnevicne]

Confirming.
I got a popup yesterday night informing me that an update of one of an installed library was available. Opened the library manager and it I could select version 2.3.2 for OneWire and perform the update.
So all good for me :-)
