Fixed bugs:
- E-commerce - In certain cases, when utilizing the web part-based checkout process on Portal Engine sites, a previously selected shipping option incorrectly persisted over multiple orders, even though the orders did not contain any shippable items. Furthermore, when using custom shipping carrier providers, removing all shippable items from an order after a shipping option has been selected resulted in an error in certain cases.
- E-commerce - The 'Customer detail' web part did not validate the uniqueness of entered email addresses for signed-in users. If the entered email address was already registered in the system (e.g., by another user), this could have resulted in two users with identical addresses (due to the way the system merged the submitted information with the internal user object).
- General - When the Kentico application was running behind a proxy server or some other service that masks the application's original domain (e.g., Azure Application Gateway), it generated certain requests with incorrect URLs. This caused errors in parts of the application (e.g., when uploading files into Media libraries). When hosting the Kentico application behind a proxy server, developers need to set the 'CMSUrlHost' web.config key (added by the hotfix) to the 'host' component of the proxy server's URL to ensure the application correctly generates request URLs. Please note that this configuration currently applies only for Portal Engine projects. See the hotfix instructions for more information.
- MVC - Installing or updating the 'Kentico.AspNet.Mvc' NuGet package added an empty 'CMSConnectionString' <add> element to the 'connectionStrings' section in the web.config file, if it was not already present. This could cause errors in certain scenarios, for example when using an external connection string file specified via the 'configSource' attribute. The same problem could occur also for the 'appSettings' section with specified 'configSource', where the NuGet installation was adding the 'CMSHashStringSalt' app setting. Versions 12.0.35 and newer of the package no longer add the empty 'CMSConnectionString' and 'CMSHashStringSalt' elements when the 'configSource' attribute is present in their parent section.
- In case of external config sources, developers need to manually specify the 'CMSConnectionString' connection string and the 'CMSHashStringSalt' app setting in the external config files.
- Web farms - In special cases, the system accumulated redundant records by repeatedly failing to delete the records from the 'CMS_WebFarmTask' database table.
