Migrating from 3.1.42 to the current 3.2.x of JEvents

I hesitate to use the Update function on Jevents because I have complicated template overrides for the following files:

my-template/html/com_jevents/alternative/month/...
...calendar.php
...calendar_body.php
...calendar_cell.php
my-template/html/com_jevents/helpers/...
...defaultviewnavtablebar.php
...defaulteventmanagementdialog.php
my-template/html/com_jevents/alternative/assets/css/events_css.css
my-template/html/com_jevents/assets/images/logo.gif

In particular it is several days of work to re-engineer the overrides if the first three of those files change. So I need to plan before pressing the Update button.

Will the files that these overrides replace (especially the first three files) be unchanged in going from 3.1.42 to the current Jevents version? Or will I have to re-engineer all of the overrides?

Is there a list of which files are changed from 3.1 to 3.2?

Thanks for your attention.
