https://archive.blender.org/developer/D13885 has added several
messages that mentioned OpenGL 3.3 as minimum requirement.
Blender 4.0 requires OpenGL 4.3 and this PR updates these messages.

https://archive.blender.org/developer/D13885 has added several
messages that still mentioned OpenGL 3.3 as minimum requirement.
Blender 4.0 requires OpenGL 4.3 and this PR updates these messages.

Hello just a quick question what is the point of changing version for openGL. (I am not questioning the change it is just for my personal culture and to better understand the change)
Thanks in advance

Hello just a quick question what is the point of changing version for openGL. (I am not questioning the change it is just for my personal culture and to better understand the change)

Blender uses OpenGL as the main graphics API on Windows and Linux. Different versions of OpenGL offer different features (E.G. OpenGL 4.X offers different/more features than OpenGL 3.3).

Recent changes to Blender/EEVEE have resulted in Blender making use of some features that are exclusive to newer versions of OpenGL (4.X). These features may be used to simply code, add new features to Blender, do certain performance optimizations, or prepare for upcoming features.

As a result of the use of newer OpenGL features, if a GPU driver doesn't support those features, and Blender attempts to use them, then Blender may crash or some unexpected behavior may occur. So to avoid these issues, the minimum "supported" OpenGL version gets increased so if users have a device that doesn't support that OpenGL version or newer, they get a warning message letting them know about this.
