Is there any release branch or tag of current project?

[Qiushi Zhang]

It looks like there is only one main branch in the current project, I've no idea whether it's a stable version.

[Paul Wankadia]

The absence of tags/releases implies that TCMalloc follows the "live at head" philosophy à la Abseil. Bzlmod may necessitate explicit versioning in the not too distant future, however, so it's likely worth considering what model to support in that regard.

@junyer is correct in that we follow a "live at head" philosophy.
