Your submission has now been accepted! Thanks for your contribution to the Arduino Library Manager index.

The library(s) will be available for installation via Library Manager within a day's time.

You can check the logs from the Library Manager indexer for your library(s) here:
http://downloads.arduino.cc/libraries/logs/github.com/AirNgin/Airngin-esp32-mqtt-client/

[AirNgin]

@ArduinoBot I have addressed the issues and created a new release (0.0.2). Please check again.

Hello @AirNgin. The automated system here only operates on open pull requests. Since your submission was already accepted and the pull request merged, the bot completely ignores this pull request thread, and thus commenting here doesn't achieve anything. However, the human maintainers of the registry do monitor all activity in this repository in order to assist the library maintainers with any problems they might have, so please don't make unnecessary comments on the pull request threads.

After the initial addition of the library, the indexer job periodically checks each of the libraries in the index and picks up any new release/tag that meets the requirements listed here:

https://github.com/arduino/library-registry/blob/main/FAQ.md#what-are-the-requirements-for-publishing-new-releases-of-libraries-already-in-the-library-manager-list

This means that there is no need to take any additional action to add new releases of your library to Library Manager. They will be added automagically!

It does take a little time for the indexer job to run, and then some additional time after that for the update to propagate through the CDN and the local cache. But it will get there. We give a conservative estimate of availability within one day's time.

You can monitor the indexing of the library releases by checking the library's dedicated indexer logs web page:
https://github.com/arduino/library-registry/blob/main/FAQ.md#user-content-can-i-check-on-library-releases-being-added-to-library-manager

---

If you found the checks the bot ran on your submission to be useful, you might consider setting up similar checks in your library repository for compliance with the Library Manager requirements and general best practices. You can make these checks automatically run on every commit and pull request to ensure such violations are caught immediately.

Arduino provides a GitHub Actions action that makes this very easy to do by adding a simple YAML file to the repository:

https://github.com/arduino/arduino-lint-action#readme

This action uses the same Arduino Lint tool as the Library Manager system.

It is in use in all the official Arduino library repositories (example).

hi, I updated my library 3 weeks ago, but I can’t see the new version in the Arduino library manager.

[per1234]

Hi @AirNgin. When there is a problem with the publishing of your library in Library Manager, you should check the dedicated logs page for the library. The URL was provided in the comment from the bot above.

If we look at that page:

https://downloads.arduino.cc/libraries/logs/github.com/AirNgin/Airngin-esp32-mqtt-client/

we see this:

2025/02/01 09:06:20 Checking out tag: 0.0.2
2025/02/01 09:06:20 Release AirNgin:0.0.2 has wrong library name, should be AirNgin ESP32 MQTT Client
2025/02/01 09:06:20 Checking out tag: 0.0.3
2025/02/01 09:06:20 Release AirNgin:0.0.3 has wrong library name, should be AirNgin ESP32 MQTT Client
2025/02/01 09:06:20 Checking out tag: 0.0.4
2025/02/01 09:06:20 Release AirNgin:0.0.4 has wrong library name, should be AirNgin ESP32 MQTT Client
2025/02/01 09:06:20 Checking out tag: 0.1.0
2025/02/01 09:06:20 Release AirNgin:0.1.0 has wrong library name, should be AirNgin ESP32 MQTT Client

The name is the sole unique identifier for a library in the Library Manager system. This identifier is used in command line applications and in the metadata of dependent projects. For this reason, the library is locked to the name it had at the time of registration. Any release that has a different name from the registered name in the metadata is rejected.

Your library was registered under the name AirNgin ESP32 MQTT Client. You later changed the name to AirNgin:

AirNgin/Airngin-esp32-mqtt-client@c8841ae

diff --git a/library.properties b/library.properties
index 4f7b8fb..b5d09f4 100644
--- a/library.properties
+++ b/library.properties
@@ -1,9 +1,9 @@
-name=AirNgin ESP32 MQTT Client
+name=AirNgin
 version=0.0.1
 author=AirNgin Team

So all the releases you made after that change were rejected.

There are two options for fixing the problem. I'll describe them below. You can choose whichever one of the options you think is most appropriate for your library:

A. Revert Name Change

1. Change the value of the name property in the library's library.properties file back to the registered name AirNgin ESP32 MQTT Client:

   name=AirNgin ESP32 MQTT Client
   

2. Bump the value of the version property in the library's library.properties metadata file.
3. Create a new release or tag in the library repository.

Within a day of performing that procedure, you should find the new release in the Arduino Library Manager. Note that the previous non-compliant releases will still be missing.

B. Request Change to Registered Name

If you are sure you want to change the library name to AirNgin, you can submit a request for the library's registration to be updated by following the procedure documented here:

https://github.com/arduino/library-registry/blob/main/FAQ.md#how-can-i-change-a-librarys-name

Please note that it is necessary for a human maintainer to perform an operation on Arduino's internal database in order to accommodate a name change request. It might take a couple of weeks before the maintainer finds the time to perform that operation so you should not expect the registration update to occur immediately.

After the library's registration is updated, all releases that have the new name in their metadata will be listed in Library Manager. The 0.0.1 release you made under the original name will no longer be listed.
