Blocking issue: #10879

[trivialfis]

@hcho3 Does it affect the 2.1 branch?

[hcho3]

Is the JVM rewrite part of 2.1.2 ?

[trivialfis]

No. It's a patch release for bug fixes.

[jprafael]

@trivialfis Does this release also include #10527?

[trivialfis]

Thank you for the reminder, added to the list.

@hcho3 Could you please help take a look into the new release script, I'm running into:

twine check /home/jiamingy/workspace/xgboost_dev/xgboost/python-package/dist/xgboost-2.1.2.tar.gz
ERROR    InvalidDistribution: Cannot find file (or expand pattern):                                                       '/home/jiamingy/workspace/xgboost_dev/xgboost/python-package/dist/xgboost-2.1.2.tar.gz' 

when doing twine check.

In addition, this line is not needed, the url uses the full branch name.

[trivialfis]

NVM, I think I didn't update the tag correctly.

[trivialfis]

Done.
