• Version: 3.13.1 (12b99393438a4cc9e478e33459eed78bec6233fd, 2021)

• All cpp files listed in modules/raycast/godot_update_embree.py
• All header files in the directories listed in modules/raycast/godot_update_embree.py

The modules/raycast/godot_update_embree.py script can be used to pull the relevant files from the latest Embree release and apply some automatic changes.

Some changes have been made in order to remove exceptions and fix minor build errors. They are marked with // -- GODOT start -- and // -- GODOT end -- comments. Apply the patches in the patches/ folder when syncing on newer upstream commits.

enet

• Upstream: http://enet.bespin.org
• Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)

Files extracted from upstream source:

• all .c files in the main directory (except unix.c win32.c)
• the include/enet/ folder as enet/ (except unix.h win32.h)

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by Godot's socket implementation and allow IPv6 and DTLS. Apply the patches in the patches/ folder when syncing on newer upstream commits.

Three files (godot.cpp, enet/godot.h, enet/godot_ext.h) have been added to provide enet socket implementation using Godot classes.

It is still possible to build against a system wide ENet but doing so will limit its functionality to IPv4 only.
