Forge 1.20

- Creative mode tabs are now a registry; the `BuildContents` event was renamed to `BuildCreativeModeTabContentsEvent` and moved it to its own class
- The pack format is now 15 for both resource packs and data packs
- `ScreenUtils` was deprecated in favor of a `GuiGraphics` extension
- Forge and the MDK were updated to Gradle 8 and FG6
- The Forge common config file was removed (it only contained the deprecated old fields for resource caching, which was removed in 1.19.3)
- Registry dummy entries were removed
- `RemappingVertexPipeline` was fixed to forward the `endVertex()` call
- Forge tool tags were removed in favor of vanilla ones

  1. If you can find the name of a mod in the trace, that mod most likely is the culprit.
     - Be aware that you may find multiple mods as participants of a crash. In that case, you can either report to both or try to reason (using the names in the stacktrace) about which mod is at fault.
  2. If you can only find Forge (usually starting with `net.minecraftforge`) alongside Vanilla (usually starting with `net.minecraft`) references, chances are that you have found a bug in Forge. In this case, use one of the various [support channels](#forge-support) listed below.
-    - The occurence of a single call to Forge somewhere in the stacktrace *does not* warrant a report to Forge if there are mods present in the crash report.
+    - The occurrence of a single call to Forge somewhere in the stacktrace *does not* warrant a report to Forge if there are mods present in the crash report.
  3. If there's no mention of Forge or a mod, but any Vanilla class, you might have found a Vanilla bug. You should probably still report it via the Forge channels first, however, due the nature of modded environments and the rarity of Vanilla crash bugs.
  4. Always check whether there's a mention of coremods at the beginning of a crash report. If there is and you can't find any clear culprit, consider reporting to these coremods first, since they are free to change any of the code executed in your environment.

 If you're certain you've found an issue that is directly caused by Forge, you have the following three platforms available for dealing with it, with decreasing relevance for end-users:
 
- 1. **Forge Forums:** There's a dedicated [Support & Bug Report](http://www.minecraftforge.net/forum/forum/18-support-bug-reports/) section on the Forge forums, which is led by team of moderators and volunteers who will try to deal with your reports as quickly as possible. *As a player you should probably report here first.*
-   - For modders, there also is a separate [Modder Support](http://www.minecraftforge.net/forum/forum/70-modder-support/) section where you can ask all your development-related questions. *You should prefer this section for coding help.*
- 2. **Forge Discord Server:** You can find a lot of help on the official [Discord Server](https://discord.gg/forge), especially smaller issues that you quickly need help with. *Be aware that the channel is more suited towards development questions, so while you may get support there as a player, you should almost always prefer the forums.*
- 3. **Forge Issue Tracker:** If you're absolutely certain that you've found an issue in the Forge codebase (e.g. you're a modder yourself and have analyzed the stacktrace and relevant code), don't refrain from reporting it on this repository's [issue tracker](https://github.com/MinecraftForge/MinecraftForge/issues). *Please do not use the issues as a means of getting coding help.

 ### Preventing Duplicates and Unnecessary Reports
 Use the target issue tracker's search functionality to look for issues which have descriptions similar to yours, but make sure to also search for already closed issues. If you can find one, verify it is in fact the same (or a very similar issue) and simply comment on it if you have anything else to contribute to the discussion, such as other steps to reproduce it. *Do not create duplicates of an existing issue, since it only puts extra effort on maintainers to recognize and close/mark them.*
 
-Additionally, always check the *latest* changelogs of Forge and participating mods to find out if the bug was already noticed and fixed by the developer. Often the maintainer may only support newer versions of the game, so also check the changelogs for versions of Minecraft you don't actually actively play. If the issue was adressed already, *do not report it*, even if the fix only exists for a newer version of the game, since the developer probably had a good reason to do so. If your issue only exists with versions of a mod that are for very old versions of the game, also refrain from reporting them, considering most modders only support the two latest versions of Minecraft, if at all.

 Every project has a different way of dealing with issues, so don't wonder if there's no comment on it, but somebody "labels" it with certain markers. This helps developers to more easily keep track of bugs and priorities. When any further input from you is required, you will be asked specifically. Do not bug anyone through other channels about resolving your issue.
