: V13 relies on project archiving and manual merging. V16/V17 features a dedicated Multiuser Server for simultaneous team engineering. Best Practices for Running V13 SP1 in 2021
An additional complication emerged for users of older versions attempting to update their software: V13 versions prior to SP2 Update 4 lacked the required TLS 1.2 security protocol support to connect directly to Siemens’ update servers. This meant that users needed to manually download and install the complete V13 SP2 Update 4 package rather than using the automated updater. For organizations without a local Siemens Update Server configured for V13 compatibility, this manual approach was the only viable option.

However, I would advise users to:
Update 4 was "better" in the context of its time because it fixed many of the early bugs of the V13 platform. However, for a professional environment in 2021, is the superior choice for V13 projects due to its modern OS support and continued availability from Siemens Industry Online Support .
Others appreciated specific features introduced in the V13 generation, including the ability to switch data blocks between optimized and non-optimized modes, drag-and-drop functionality in the WinCC environment, and a substantially improved code editor compared to the “classic” Simatic Step 7 environment.

Siemens TIA Portal (Totally Integrated Automation Portal) is a comprehensive software suite used for industrial automation and control systems. Version 13 SP1 Update 4 is a patch release that provides bug fixes, security updates, and performance improvements to the TIA Portal v13 SP1.
: Projects created in older versions (V10.5, V11, or V12) cannot be upgraded directly to V14 or higher. They must first be opened and compiled in TIA Portal V13 SP1
One of the most important characteristics of TIA Portal V13 SP1 Update 4 is its cumulative nature. This update included all the improvements and fixes from Update 1, Update 2, and Update 3, meaning that engineers could install a single package to bring their V13 SP1 installation fully up to date. This approach simplified maintenance, particularly for users who had fallen behind on applying incremental patches. This meant that users needed to manually download
is a specific legacy engineering framework patch that remains highly relevant for industrial automation engineers maintaining legacy SIMATIC systems. While newer versions like V17, V18, or V20 dominate modern greenfield deployments, factory lifecycles often mandate sticking with an established baseline to support specific hardware nodes.
