Corrected several ImpossibleActions scaffold full glass block false positives.
Corrected a few KillAura area false advantage false positives.

News:
This update significantly improves the functionality of the SQL feature with more reconnection tries, several error corrections, and stack traces to help track one's connection issue.
In addition, the inventory menus are optimised with faster loading times & eliminating the chance of the server crashing or thread dumping. This is due to relying less on the Bukkit libraries and more on custom ones.

Build 427 - ItemsAdder Compatibility

News:
Compatibility for a popular plugin named ItemsAdder has been implemented.

This is simply a try to make Spartan more universally applicable to servers.

Logs:

Build 425 - Maintenance Update

News:
This is a simple maintenance update, making sure the plugin is up to date and running correctly. Due to recent time limitations, an insignificant Jesus bypass will be fixed in a future update. I went past my update schedule this time, because why not. Any issues, report them privately via Discord, Platform or Email, and take care.

Preventions were studied but were already significantly good, so only a few improvements were made in delays & hacker identification consideration.

Spartan will no longer appear in the kick, ban or warning reasons.
Corrected a few Jesus ypos abstract liquid blocks false positives.

Build 423 - Rewritten Detections/Utilities & Many Issue Corrections

News:
Many detections & utilities were partly written in this update, including ones from the Ground utilities. Fly check, IrregularMovements check & Speed check. These changes aim to solve instabilities that have been existing for a few updates now for several but not all of you.
A lag issue was corrected by optimising a method of the Search Engine handler, specifically one responsible for detecting unstable checks & detections. Additional caching has been implemented to help this method now run as fast as possible.
Since the Search Engine handler’s inception, it’s known that if you disable both File & SQL logs, it will disable, taking down an important analysis part of the anti-cheat. This update changes this by forcing the Search Engine to partly work despite all significant log options being disabled.
A major bug was discovered in the Configuration system that prevented legacy commands from being executed in many scenarios. This update corrects this issue and any old configurations should once again function per usual.

Logs:
Corrected several BoatMove multiple passengers false positives.
Corrected several FastBreak breaks-per-second entity block false positives.
Corrected dozens of movement false positives caused by elytra gliding not being identified properly.
Corrected an issue where players could not be unbanned due to a small bug in the system.

Build 421 - HotFix #1

Corrected a Search Engine object refresh issue for a large variety of users. Updating is extremely recommended.

Build 421 - Enchantment Plugin Compatiblities & Performance Improvements

News:
Two new compatibilities were implemented in this update, both related to enchantment plugins, which are difficult to implement. Feel free to check them out via the compatibility disclaimer/docs.
The Search Engine handler, responsible for analysing Spartan’s logs, will now update automatically via its objects, meaning performance will decrease and get more stable by significantly reducing CPU & RAM usage. This process will only still occur if Spartan has its SQL feature configured, which is necessary for the retrieval of external server data.

Potentially corrected several Clip instant falling false positives by correcting an air-ticks reset bug.
Implemented a new method for the API events.
Corrected a Configuration replace reset bug.
Corrected a Spartan inventory menu null-pointer console error.
Corrected a Violations feature potential null-pointer console error.
Slightly optimised the Cancel Violation handler with faster math calculations and less memory usage.
Potentially corrected a few Velocity near semi-solid block false positives.

Build 420 - Automated Stability Improvements

News:
Spartan has long been able to detect problematic detections, therefore also problematic checks. This update takes this feature even further by allowing it to disable/modify specific detections in specific circumstances. Spartan runs in a large variety of servers, so despite the calculations that take place in the background, sometimes it’s best to disable a small part of a check to improve the overall stability.
Spartan’s checks run on the main thread, but other codes such as systems, handlers, features may run asynchronously. Rarely, big servers would have issues with the Chunks system’s cache, as rapid loading/unloading would simply make it too heavy. This update corrects this issue but using native Java libraries that optimise the Chunks system, making it 3-4 times lighter.

Logs:
Corrected dozens of 1.17 datapack world y-position less than 0 false positives.
Corrected several MorePackets instant identification low violation false positives.

Corrected a few Fly stable slow falling effect false positives.
Slightly improved the Cloud feature with increased verification time for Syn.
Noticeably improve the Chunks system with 3-4 times faster cache.
Corrected a bug where Spartan’s tab completion would show vanished/hidden players.
Potentially corrected several ElytraMove speed false positives.
Potentially corrected a few FastBreak veinMiner compatibility false positives.

Build 419 - HotFix #1

Update to this version only if you are using a 1.17 server with data-pack world/s, it will solve a great variety of false positives. Cross-version support remains.

Build 419 - Many Instability Corrections

News:
Last few updates were big, with two of them being major. Build 418 wasn’t very stable, so it’s recommended to update to Build 419. This update polishes the recent changes made to the code and improves existing ones that a few of you have been rightfully complaining about.

Logs:
Potentially corrected dozens of Jesus ypos above water building false positives.
Disabled forceful preventions for the MorePackets check when violations are zero.
Reversed some changes made to the Fly & IrregularMovements check to reduce false positives.

Noticeably optimised the Material utilities with better usage of its methods.
Slightly improved the mcMMO plugin compatibility with more error-proof methods.
Slightly improved the Block utilities with more accurate methods.
Corrected dozens of Fly false positives caused by the Spartan Location object.

Build 418 - Improved Lag Leniencies & KillAura Check Correction

News:
Spartan’s lag leniencies have largely improved by having their purpose rearranged. Many calculations were removed where they were no longer needed or simply never needed. This will help with dealing with hackers that use ping-spoof modules to increase their latency in order to give themselves an unfair advantage.
A major was found in one of Spartan’s objects that caused a number to not increase, resulting in a big part of the KillAura check to not work properly or at all. This has been fixed, so you should expect better & faster detections.

Logs:
Completely rewritten the lag leniencies of the plugin to work in par with the server’s needs instead of limit calculations.
Corrected several 1.17+ movement false positives caused by the brand new light block.
Corrected a major bug in the Buffer object that prevented most of the KillAura check from working properly.
