When Microsoft Dynamics 365 for Finance and Operations was launched, the recommendation was to implement customer-specific customisations as extensions rather than through overlayering. With extension-based development, in contrast to overlayering, the base code is not overwritten. This has the advantage that application hotfixes and updates can be applied without modifying and recompiling the customer-specific code. In other words, the application remains upgradeable at all times. With version 8.0, Microsoft goes even further and has 'hard-sealed' the application models. This effectively means that enhancements are now only possible through extensions. The reasons for strictly avoiding modifications to the standard code are obvious. An update to a newer version can therefore be installed far more easily — unlike in earlier versions, where the entire code first had to be reconciled. In addition, the security of the application and of the company data it contains is the top priority. This enables Microsoft to roll out security updates automatically, without any need to recompile the customer-specific customisations. Since 1 July 2018, hotfixes and security updates have been installed automatically by Microsoft for customers running Platform Update 12 or higher. According to the latest roadmap, the goal is to achieve a 'ONE Version' for Microsoft Dynamics 365 for Finance and Operations. In this context, Microsoft refers to uninterrupted updates (Zero Downtime). More about the upcoming October 2018 release…
