The analyzer was built to go off syntax nodes. This (AFAICT) meant that the SemanticModel had to be recalculated for every single invocation.
If you don't know what the above means: it basically means the compiler has to re-analyze the entire file.
Fix this by moving it to an operation analyzer so the compiler can properly cache the semantic model.
This was an undocumented breaking change introduced by https://github.com/space-wizards/RobustToolbox/pull/5915. The behavior does not make much sense: you're specifying coordinates relative to the map, so the rotation should be relative to the map too.
Apparently cheat clients have figured out that none of SS14's code does validation against NaN inputs. Uh oh.
IRobustSerializer can now be configured to remove NaN values when reading. This is intended to be set on the server to completely block the issue.
Added "Unsafe" float types that can be used to bypass the new configurable behavior, in case somebody *really* needs NaNs.
An alternative option was to make a "SafeFloat" type, and only apply the sanitization to that. The problem is that would require updating hundreds if not thousands of messages in SS14, and probably significantly confuse contributors on "when use what." Blocking NaNs by default is likely to cause little issues while ensuring the entire exploit is guaranteed impossible.

* Transfer impl for Lidgren
* Async impl for receive stream
* Use unbounded channel for Lidgren
* Add metrics

* Release notes
This means we don't have to JIT a bunch of UIs that you might not open, reducing memory usage and startup overhead.
One (1) UI is always JITed in another thread before prototype UIs are loaded, so as to warm up the JIT machinery. Said type is DropDownDebugConsole which always gets used anyways so there's no harm in it.
In total, these changes save more than a second of startup time for me.
