[+] Spartan now optionally works with Packets. You need ProtocolLib for this.
[+] KillAura MoveDirection detection with the heuristics:
 - basic
 - low
 - sync
 - aim
 - constant
 - aggressive
 - switch
 - pattern(random)
 - pattern(snap)
 - pattern(gcd)
[+] Rewritten Criticals check
[+] Rewritten Velocity check (ProtocolLib Only)
[+] Rewritten HitReach check (Covers 3.01+ Distance) (ProtocolLib Only)
[+] KillAura HitTime detection (ProtocolLib Only)
[#] Fixed many false positives caused by several checks.
[#] Improved detection information in the KillAura & HitReach checks.

Added support for Minecraft 1.21

Fixed a few final issues, although the previous update was already stable.

Improved the memory consumption of the plugin and corrected console errors found by a few of you. Updating is necessary.

Fixed all remaining issues found by a few of you.

Fixed a few problems noticed by a few, updating is more than recommended.

Thank you to the many for patiently waiting. Here's a full rewrite of the movement checks. Words are few to describe the maze one has to go through to make such an update, try the movement checks and see for yourself the results!

This update once again brings huge improvements to Spartan.

1. The Cancel Violation and False Positive Detection algorithms have been incorporated in the Live Violation algorithm, saving your server's resources in the process.
2. The Machine Learning algorithm has been further developed and now uses less memory while running faster, plus I will be using to implement its first detections in the future.
3. Violations are now uncapped where previously they would go up to 100 per minute and are time linear, meaning they will decrease as time passes if a player is not hacking. This will offer greater stability while improving long term statistics with undisputed evidence.
4. Last but not least, the plugin was once again deeply maintained with outdated handlers and listeners being rewritten to track data better while consuming less resources from your server.
5. The rest is history: https://github.com/IdealisticAI/Spartan-AntiCheat/commit/a0efe1eab03edeed1f442374c4740d93d8e50020

This update introduces Machine Learning training algorithms for the movement checks. There are no detections yet implemented, although successful testing of a few has been conducted. I will be measuring the effects of this update to fix any potential issues introduced but to also help all of you gather data for when the detections are implemented.

This hotfix fully stabilizes this update and is recommended for everyone. If you are still in Phase 532 or earlier, I urge you to update, but it will not be so necessary for the already stable Phase 532.1 update.

Fixed a few console errors. Sorry folks, this update was massive, it was kind of expected, but now all good.

Since I decided to bring Machine Learning to Spartan, it is necessary to do a deep cleaning and maintenance of the plugin's code, which is what I've done with this update. This could be my biggest update so far, although I won't make such a claim. However, the title is more than true, the plugin has been hugely improved from top to bottom with attention being paid down to specific details. Here are all the changes: https://github.com/IdealisticAI/Spartan-AntiCheat/commit/92269268f6c0d4113fd2f036eb599a63636be9d6

I will be conducting a Machine Learning project for Spartan in the future, if you wish to participate as a BETA Tester and help me train new algorithms but also get them ready for production, feel free to participate by joining at https://www.idealistic.ai/discord and reacting in my recent news message. Thank you!

1. Removed a forgotten debug message.
2. Ignored always using isCancelled in the PlayerDeathEvent.
3. Fixed a Damage Cause console error.

Hey folks, I hope you are all doing great. I wanted to notify that this update removes the Ban, Report, Debug & Spectate functionalities. I did this as my time is limited due to heavy workload and I want to focus only in what's important, which is checks and their respective detections that you should expect upgrades in the future. Unfortunately, moderation functionalities is not one of them and never has been, and I'd rather remove them than keep them there unmaintained with poorly implemented code of my younger self, with overall limited functionality and better alternatives available at many other places. Kicks and warnings still exist and should serve you well.

1. Fixed a memory bug where messages would remain outdated and show Spartan 1.0 instead of 2.0.
2. Added support for the “allowPublicKeyRetrieval” SQL option in sql.yml.
3. Made the IrregularMovements equilibrium detection not increase violations when distance traveled is too low.
4. Hackers will now require evidence from 2 checks instead of previously 3 checks.
5. Removed the Detection Tick functionality and balanced the use of the Move event.
6. Removed the default ‘spartan {player} if {tps} > 18.0 do’ unnecessary part of the punishment command.
7. Spartan will no longer be responsible for measuring the stability of your server’s TPS.
8. Removed the ban, unban, ban-info, report, spectate commands and their respective options because it’s not worth for Spartan to focus on low-quality moderation functionalities.
9. Removed the spectate & debug functionalities and their respective options & items because it’s not worth for Spartan to focus on low-quality moderation functionalities.

Same version but with obfuscation corrections to fix a command error.

1. Corrected an eco-enchants compatibility console error.
2. Punishments will now be broadcasted by default.
3. The False Positive Detection functionality will enable after a certain amount of collected data.
4. Updated the Discord invite link and the inventory menu item arrangements.
5. Cloud Staff Announcements will now be responsbile for the outdated version check.
6. Did maintenance on the MorePackets check.
7. Adjusted the Player Opponent object to be more precise and more frequently updated.
8. Rewrote the Violation Statistics algorithm to be probability based.

1. Fixed console errors related to packets and folia.
2. Fixed log & wood false positives in ImpossilbeActions check.
3. Optimized the Research Engine’s handler data flow and update rate.
4. Separated evidence calculation into live and historical.

Corrected a console error related to the KillAura strafe detection.

1. Bedrock compatibility will now consider the prefix regardless of Floodgate.
2. Adjusted the SpartanPlayer object to be more async friendly in regards to the Folia fork.
3. Added handler for bridge building to prevent false positives.
4. Adjusted the SpartanPlayer object to collect certain data in a tick-based fashion for more accuracy.
5. Adjusted certain tracking objects to get the precise amount of ticks remaining for more accuracy.
