Official Source: The CODESYS Store provides free access to the development environment, though you may need to search the archive section for specific older versions like 2.3.9.
Manufacturer Portals: Since V2.3 is often hardware-specific, it is frequently downloaded via manufacturer support pages like WAGO or Eaton (XSoft). "Interesting Review" & Community Insights
User experiences highlight several quirks regarding stability and versioning:
The "Library Overwrite" Trap: A critical community "review" warning emphasizes caution when upgrading within the 2.3.9 series. Because CODESYS V2.3 libraries often keep the same names across revisions, an update can overwrite stable old libraries with newer versions that might contain bugs, potentially breaking existing POUs (Program Organization Units).
Access Rights Shifting: Users have noted that between versions like 2.3.7 and 2.3.9.4, "Read Only" access rights for visualizations became more restrictive, sometimes locking technicians out of interactive buttons they could previously use.
Multi-Developer Synchronization: A common complaint involves "login without download" issues when multiple developers work on the same project stored on a server. The IDE's reliance on timestamps can trigger a mandatory re-download even if no code changed, simply because the project was saved on a different local machine.
Stability Warning: Long-time users (8+ years) have reported rare but catastrophic crashes in 2.3.9 where project files became unreadable, making external backups mandatory. Key Specifications for V2.3 XSoft-Codesys 2.3.9 Crashed, I can't load my project now
