Blender 2.80 development plans from Blender Developers Blog:
Normal maps are usually saved in one of the two most common formats: OpenGL or DirectX. Blender uses OpenGL specification. Trying to use normal maps saved in another format will result in the wrong visual effect. To convert normal maps to the desired format the “OpenGL – DirectX Normal Map Converter” node group from the BIS material library can be used.
The samples of use:

Add-on registration and removing were made with the “Window manager” (wm) in Blender 2.7 Python API:
|
1 2 3 4 5 |
bpy.ops.wm.addon_install(filepath='_path_to_addon', overwrite=True) bpy.ops.wm.addon_enable(module='addon_name') bpy.ops.wm.addon_remove(module='addon_name') |
In Blender 2.8 API add-on operators moved to the “preferences”:
|
1 2 3 4 5 |
bpy.ops.preferences.addon_install(filepath='_path_to_addon', overwrite=True) bpy.ops.preferences.addon_enable(module='addon_name') bpy.ops.preferences.addon_remove(module='addon_name') |
3D-cursor location property
|
1 |
context.scene.cursor_location |
in Blender 2.8 API moved to “cursor” object
|
1 |
context.scene.cursor.location |
When trying to get the cursor location through the “context.scene.cursor_location” Blender throws an error:
‘Scene’ object has no attribute ‘cursor_location’
When developing add-ons it is often necessary to give an ability to set a number of parameters that affect the whole add-on work to the user. For example, the user can specify a directory for saving/loading files, set some default variables or switch between add-on modes. Of course, the interface for setting such parameters can be placed in the add-on panel, but it is better to place it in a separate add-on preferences panel, which is located in the “Preferences” window under the add-on installation panel.
The main advantage of the add-on preferences is that they don’t reset when Blender restarts. The user does not need to configure the add-on preferences each time, it’s enough to set the necessary parameters once, personalizing the add-on for convenient work.
Let’s create an add-on and define a parameter, placing it in the add-on preferences panel.
In Blender 2.7 the “*” (star) operator is used in the matrix, vector, and quaternion multiplication. In Blender 2.8 it is replaced with the “@” (at) operator.
If the “*” operator is used in vector, matrix or quaternion multiplication in Blender 2.8 it throws an error:
Element-wise multiplication: not supported between ‘Matrix’ and ‘Matrix’ types
Proper use of the “@” operator:

bpy.context.region_data.view_rotation @ Vector((0.0, 0.0, 1.0)) |
