 	- [ ] 3.1 **Test in different operative systems** - This step is not necessary every time, but testing the commands in Stata on each of the PC, Mac and Linux operative systems should be done from time to time. A particularly good time to do this is after writing or editing code that depends on file paths, the console, special settings etc. If small updates are needed, then do them in the _version_ branch, otherwise do them in branches of the `develop` branch, merge those to `develop` and then re-merge `develop` to the version branch and test again.
 	- [ ] 3.2 **Update version and date** - In the _version_ branch, update the version number and date in all ado-files and all dates in all help files. See section below for details.
 	- [ ] 3.3 **Update version locals in ietoolkit** - In the _ietoolkit.ado_ file in the _version_ branch, update the _version_ and _versionDate_ locals at the top of the file.
-	- [ ] 3.4 **Update version in .pkg and .toc** - This has nothing to do with SSC but should be kept up to date to. This is for when people install directly through GitHub using `net install`
-	- [ ] 3.5 **Create a .zip file** - Create a .zip file with all ado-files and help files in the folder you just created in the archive folder. Then remove all files but the .zip file from the archive folder.

+	- [ ] 3.5 **Create a .zip file** - Create a .zip file with all ado-files and help files only. These files are not allowed to be in a sub-folder in this .zip file. No other files should be in this folder. Make a copy of this file in the archive folder of this package.
+- [ ] 4. **Email Prof. Baum** - Email the .zip file created in step 3.5 to **kit.baum@bc.edu**.
 	- [ ] 4.1 - If any commands are added or deleted, make note of that in the email.

+	- [ ] 4.2 - If any of the meta info (title, description, keywords, version or author/contact) has changed then include those updates in your email.
 - [ ] 5. **Draft release note** - Go to the [release notes](https://github.com/worldbank/ietoolkit/releases) and draft a new release note for the new version. Follow the format from previous releases with links to [issues](https://github.com/worldbank/ietoolkit/issues) solved.
 - [ ] 6. **Wait for publication confirmation** - Do not proceed pass this step until Prof. Baum has confirmed that the new version is uploaded to the servers.
 - [ ] 7. **Merge version branch to *master*** - If step 2 and 3 was done correctly, then there should not be any merge conflicts in this step. Once merged, delete the `version` branch.

+{pstd}The balance variables must all be continuous or binary variables.
+Categorical variables (for example 1=single, 2=married, 3=divorced) should not be used as a balance variables,
+since t-testing would inappropriately compare the mean of the underlying codes, which are not intended as numerical values.
+Categorical variables must first be made into multiple binary dummy variables,
+where each dummy represents one category in the categorical variable,
+and the dummy is 1 if that category was used for that observation.
+t-tests will be used to test differences in balance variables
+regardless if the balance variable is continuous or binary,
+even though that is not the most efficient test for binary variables.
+See the command {stata ssc describe table1:table1} for a command that handles categorical variables
+ and allows you to test differences using other tests than t-tests.

 {pstd}The command also attaches notes to the bottom of the table with information on, for example,
 	which significance levels are used for stars, which fixed effects or covariates that were included (if any) etc.
