According to Semver, #166 would imply backward incompatible changes. Therefore, version would increase to 3.0.0 instead of 2.3.0.

This issue branch was 3 commits behind the main branch. I brought up to date this issue branch with the main branch after bringing commits https://github.com/JMSLab/xtevent/commit/4198174fab4a012e3ab69eca0b76f2ecc9199e40, https://github.com/JMSLab/xtevent/commit/8cabed50efd6d02132e3c66d56203b6ff2099591, https://github.com/JMSLab/xtevent/commit/dbe046a862859262b098f82e24ab787932f78a55. The branch is now up to date with main.

@jorpppp in https://github.com/JMSLab/xtevent/commit/dc9b4f95432bea6502d636d52d3f4740234d7810 I updated examples in the test file using the option for the label for the mean of the dependent variable since it changed in commit https://github.com/JMSLab/xtevent/commit/97cbccd4c3c1bb305753197eb891f55b1900a1da

I got an error message when running the test file's examples with the option addabsorb. For instance, when running:

xtevent y eta, policyvar(z) window(3) proxy(x) nofe note addabsorb(k) reghdfe

I got the error message:

last estimates not found
r(301);

I had the latest ssc version of reghdfe installed. After revisiting a little, I found the problem came from reghdfe (and not from xtevent). This statalist post mentions this problem. Once I installed the latest github version of reghdfe (along with its dependencies), the code ran properly. Maybe I could add some message to the home page, in the installation section, recommending the user to install the latest github version of reghdfe. Currently, when the user installs xtevent, the program automatically tries to install the latest ssc version of reghdfe.

I didn't have any additional problems when running the rest of the examples in the test file.
