Re: [threadx] Clarification on 6.1.1 License

Hi Renz.

Everything available in the Eclipse ThreadX repositories, including older releases, is available under the MIT license. You can disregard the licensing information found in the older 6.x releases made by Microsoft. We did not update those releases retroactively to preserve the commit histories of the relevant repositories.

Best,

Hi,
 

We want to confirm if the change to MIT license applies retroactively to versions before 6.4.1, which is when the transition to open-source has completed as per this article. In the same article, it has been hinted that this change applies to all 6.x versions:

However, in the ThreadX repository, the old Microsoft license still remains for 6.1.1 (I understand that this is because versions are just tags and not on a separate branch where the license can be updated if it changes) - but I did not find this potential retroactive license change to be written anywhere else other than the article above.

I guess I am just looking for official confirmation that 6.1.1 really can be considered to be under the MIT license now. 

*Note: Why 6.1.1? It seems to be the latest version with safety certifications. While certifications for 6.4.1 are planned, we prefer to work with what's available now.
