@AprilYUZhang add also a line to CHANGELOG like you did for tinyhouse.

@AprilYUZhang add also a line to CHANGELOG like you did for tinyhouse.

@gregorgorjanc It might cause the conflict with Ros's branch, because devel didn't have CHANGELOG.md. I can write here temporarily.

## [1.2.1] - 2025-06-04
**New features**
*add ``mutation_rate`, to allow users to input mutation rate ({pr}`192`, {user}`AprilYuZhang`)
* add ``x_chr`` to replace ``sex_chr`` and  users impute data on the x chromosome ({pr}`192`, {user}`AprilYuZhang`)
**Maintenance**
* Functional and accuracy tests for X chromosome ({pr}`192`, {user}`AprilYuZhang`)

@AprilYUZhang could you update the tinyhouse reference and see if the tests pass

[AprilYUZhang]

@XingerTang now the tests passed

[XingerTang]

@AprilYUZhang Thanks! Could you trigger the pipeline here so that the GitHub runner runs your test?

[AprilYUZhang]

@XingerTang it run automatically at my repository, but here I don't know why. I didn't modify any setting, I think maybe need maintainer's approve.

@AprilYUZhang This is weird. Could you close this and open a new pull request to see if it works?
