- Non-engine modules/targets will have to specify the "version" of includes via IncludeOrderVersion in TargetRules or ModuleRules.
- This setting will control the value of UE_ENABLE_INCLUDE_ORDER_DEPRECATED_IN_XXX where XXX is the version of the engine.
- When moving types out of a header, users will need to include the new location of the type in the header it was removed from but only if UE_ENABLE_INCLUDE_ORDER_DEPRECATED_IN_XXX is set.
- If a target does not change its IncludeOrderVersion to the latest version, UBT will print out a message telling users how to upgrade.
- This change introduces a new set of SharedPCH permutations to make sure modules with older versions get the PCH with UE_ENABLE_INCLUDE_ORDER_DEPRECATED_IN_XXX set correctly.

- Provides about 8% runtime memory savings (in local tests).
- Also, adds more compression types for shaders.
- Impact on the shader compilation (in SCWs) seems to be negligible in local tests.

Local shader compiler:
- Not making 1 job batches (for High prio jobs) on startup
- Randomizing pending job selection to reduce chance that multiple 60+ sec jobs get into a single batch
(the above have the most effect on speed up, below is optional/misc)
- Pushing the completed jobs back to manager before, and not after, pulling new ones to reduce idle time
- Processing jobs in FIFO rather than LIFO order (change to LIFO seems like an ODSC regression? Hard to say definitively if it's a regression from the numbers, but seems odd to have the earliest jobs processed last)
- Parallel processing of input and output files (starts sequential by default to reduce the CPU overhead, but is enabled if we ever see too long write/read)
- More insights scopes
Distributed:
- Not avoiding local machine for XGE on startup
Both:
- Input file compression (disabled by default, need to better figure out when it's beneficial in a general case. Mostly for people with really slow I/O and XGE over VPN).
- More stats, also more dense stat output. Removed an unimportant one, added stats about the batches.

- Increased the number of jobs per XGE worker to reduce the number of times we start them. Since XGE SCWs aren't used for latency-critical jobs, this is expected to not cause user-visible delays.
- Added an ability to detect a hung distributed controller (but the build would be currently broken anyway as the jobs aren't reissued).
- Added a check for XGE system service running to avoid attempting to launch XGE on machines without it.
- Removed the code to even attempt to launch XGE XML interface.
- Also added some more logs about what's happening, and reduced the job cache verbosity.
