Version roadmap consultation

Is there an already existing issue for this?

• I have searched the existing issues

Expected behavior

Since bazel now supports code repositories, I want to support fastdds directly in the official website library, and it has been compiled based on the latest master implementation

https://github.com/daohu527/Fast-DDS/tree/master

question

So I'm eager to know our release schedule so that I can release the first bazel version, I found that there are 2 branches 2.14.x and master both have updates, and the src/cpp/CMakeLists.txt are very different.

Can you give me some advice?

Hi @daohu527, thanks for using Fast DDS.
Sorry for the inconvenience. As you have read in our repository's README, we are close to the v3.0.0 release. Fast DDS' master branch is undergoing major changes entailing API breaks. Until Fast DDS v3.0.0 is released, and it is strongly advisable to use the latest stable branch, 2.14.x. That is the reason why the CMakeLists.txt files are so different.

In the release support section, there is more information about the currently supported versions, their lifecycle and the policy for backporting ABI compatible features and bugfixes.
I hope this clarifies your doubts.

Also, I am moving this issue to the proper Q&A forum according to the Fast DDS CONTRIBUTING guidelines.

@JesusPoderoso Thanks for your reply. When will 3.0 be released? I am now faced with a choice: either wait for 3.0 or adapt 2.14.x first and then release it to the bazel repository.

Hi @daohu527, Fast DDS v3.0.0 has just been released!

[daohu527]

Does it mean that we can use version 3.0 in the future? Is version 2.0 still maintained? Which version is recommended?

[JesusPoderoso]

Yes, check each release lifecycle in the release support section.
The recommended version depends on your needs. New v3.0.0 is XTypes compliant, but 2.14.x has been more tested and it is LTS.

Thank you for your patient explanation. I am currently building a new autonomous driving system wheelos based on fastdds. I want it to be as efficient as possible and support new features, such as object-based subscriptions.

I hope fastdds will become more and more powerful

Looking forward to seeing more about the project!
