Hello everybody!
Here is one more list of important changes that can influence the work of add-ons when switching to CS-Cart version 4.1.5. Yet, there are not so many of them.
CORE
[color=#282828][font=arial, verdana, tahoma, sans-serif][size=5]===============================================[/size][/font][/color]
API: Products
You can add/update products with zero price now.
-----------------------------------------------------------------------------------------------
Themes: manifest.json
The “theme” parameter was replaced with the “logo” flag (the “theme” flag will be supported up to 4.4 version)
-----------------------------------------------------------------------------------------------
If your add-on extends the Watermarks add-on, check its functionality. There were many changes because of the bug fix.
-----------------------------------------------------------------------------------------------
Now there is an ability to install themes from the themes_repository in the Free mode.
-----------------------------------------------------------------------------------------------
Now the fn_compress_files function processes paths with dots normally.
So, now it is possible to compress files with the following names: “some_example.10.11.12.txt”
HOOKS AND FUNCTIONS
===============================================
Function fn_fpt_chmod_file was renamed to fn_ftp_chmod_file
-----------------------------------------------------------------------------------------------
The new parameter was added
[color=#b22222]-function fn_init_user_session_data(&$sess_data, $user_id)[/color]
[color=#006400]+function fn_init_user_session_data(&$sess_data, $user_id, $skip_cart_saving = false)[/color]
Thank you!
Keep up the nice job of keep us informed BEFORE the baby arrives…
[color=#282828][font=arial, verdana, tahoma, sans-serif]Thanks for the update. [/font][/color] 
[color=#282828][font=arial, verdana, tahoma, sans-serif] Look forward to the release of CS-Cart 4.1.5. [/font][/color]

v3.x addons are not compatible with the v4.x.x branch, your only option is to pay eComLabs to upgrade them for you - Sno
