I am currently trying to research differences between the IS4 and IS5 but finding it hard to get a solid comparison of the two. Does anyone have any good reasons why someone should upgrade from 4 to 5, and are there any drawbacks to upgrading?
Cheers
Version 4 will have end of support at the end of 2022, so I would recommend that you use version 5 for all new projects. Version 5.0 is basically a clone of version with some new features. So upgrading from version 4 to version 5 is very easy.
The only thing to look out for is the licensing model for version 5.
the picture below shows the relationships between the different editions:
Today you should of course be using version 6.x instead.
