Sorry for the sudden email.
I would like you to give me your advice.
This is my first post.

I have often used the package of lme4 and lmerTest to conduct a linear
mixed model analysis.
Meanwhile, I have been in trouble of which the values in the output are
slightly different between late April 2021 and August 2021.
The source code, R environment, and csv files are the same (R-3.6.1 in
Windows 10).

I surveyed and found out the following.
Around June 2020, (maybe) I installed lme4 1.1-23 and lmerTest 3.0-1.
I used these packages for a while; however I (maybe) updated lme4 1.1-26
and lmerTest 3.1-3 a few days ago (in August 2021).

I have checked the values of estimate, SE, p-value and so on in the output,
and have noticed that these were different between the packages mentioned
above.

Please advise me on the problem.
I uploaded samples of the source code and csv file.

I look forward to hearing from you.
Very sorry to bother you while you are busy, but I appreciate your
cooperation.

Best regards

If you want to check for yourself, you can retrieve older versions of 
the tarballs (.tar.gz files) from 
https://cran.r-project.org/src/contrib/Archive/lme4/

  Alternatively, if you install the 'remotes' package, you can use

remotes::install_version("lme4", "1.1-23")

- this basically automates the process of downloading the tarball and 
installing it.

  You *will* need development tools (compilers etc.) installed to do 
this (an alternative is to use the 'checkpoint' package to retrieve old 
package versions from MRAN (a versioned mirror of CRAN maintained by 
Microsoft).
