Make version semvar compliant
Removes warning log from startup
Init emptiness map lazily if needed
Fixes #56
Fix large fill commands breaking light (Vanilla)
Vanilla didn't tell the client to recalculate the edges of the
light it checked, and nor did it even tell the client
to perform the light updates. So of course it broke on chunk edges.
Fix is to simply send the neighbouring light data as well.
Fixes #71
Relocate save/load hooks into their own class
This will make compatibility with starlight better in the future for
mods that mess around with chunk NBT.
There is no forge version for 1.17 yet, so there is no RC3 for forge. No, I will not backport RC3 to 1.16.
Before that: 1.0.0-RC2 (Apr 23, 2021), 1.0.0-RC1 (Mar 28, 2021).
Starlight
==================
Fabric mod for rewriting the light engine to fix lighting performance and lighting errors.

Compatibility
Starlight can be installed either on the dedicated server or client. It is not required to be installed on both sides.
If you have Starlight on the server, clients can use Vanilla/Phosphor/Starlight to connect. Likewise, if you have Starlight on
the client, you can connect to Vanilla/Phosphor/Starlight servers.
Starlight cannot be installed with Phosphor, they are completely incompatible.
Browsing through [Starlight's Issue Tracker](github.com/PaperMC/Starlight/issues "Starlight's Issue Tracker") will show
further mod incompatibilities. Starlight is a rather destructive light engine rewrite, so it should be
expected to break mods more often.
Purpose
Starlight was developed for higher scale dedicated servers, as they suffered performance problems due to how ungodly slow the
light engine was. The only solution was to create an extremely invasive mod which rewrote the entire light engine.
I ported the mod to fabric so that I can update it during snapshots, and decided that publishing it for
all users, especially client users, would be beneficial. However, it does have the downside of being an invasive mod:
Being invasive didn't affect higher scale servers because they run on Bukkit.

can be read here: [TECHNICAL_DETAILS.md](github.com/PaperMC/Starlight/blob/fabric/TECHNI… "TECHNICAL_DETAILS.md")
Performance for 1.20:
Here are a few graphs showing performance in 2 areas on: Block editing at high y-levels, and normal block light updates:
Light engine time chunk generation Graph has been removed as a benchmark as it is invalid for 1.20. Starlight and Vanilla are close enough on 1.20 that
this test is also useless.
Performance for 1.19.4 and below:
Here are a few graphs showing performance in 3 critical areas: Chunk generation, Block editing at high y-levels, and normal block light updates:
