## 0.0.6-beta A compatibility and stability release on top of 0.0.5. The main goals were support for the newest Minecraft versions (26.1, 26.2 and 26.3), bringing back Discord alerts, a round of false-positive and exploit fixes, and fixes to the database and permissions. ### ✨ New - **Minecraft 26.1, 26.2 and 26.3 support.** Movement prediction, fluids and collisions were updated for the new versions: - Player pose tracking and the new swimming, crawling and fluid rules. - Reworked fluid handling, including per-fluid tags sent by the server. - 26.3 entity movement: the new stepped entity interpolation is modelled, so Reach and hitbox checks stay accurate on 26.3 clients. - 26.3 teleport confirmation (the client now sends its position), the new attack packet and the new animation handling. - New 26.x blocks and entities (shelf mushroom, cushion) in collisions and hitboxes. - Spear attacks and updated trigonometry for 1.21.11+ clients. - **Discord webhook alerts.** Flags and punishments can be mirrored to a Discord channel with a fully editable embed template (`discord.yml`). Messages are sent in the background, honour Discord's rate limits, and are queued (up to 200) so a burst of flags never blocks the server. Use `/jester testwebhook` to send a test message (permission `jester.testwebhook`). - **PacketEvents 2.14.1 support.** ### 🔧 Improved - **Update notifier:** staff who are already online are now told, once, as soon as a new version is found. Before, only staff who joined afterwards saw it. ### 🐛 Bug fixes - **MySQL mode now works:** the MySQL driver was being left out of the jar, so `database.type: mysql` could not connect. It is now included. - **Punishment log indexes:** on a fresh database the indexes for the punishments table were created before the table existed and were skipped. They are now created correctly. - **Safe shutdown:** pending database writes are now finished before the connection closes. Before, violations logged right before a stop or restart could be lost. - **Permissions:** `jester.alerts.silent`, `jester.verbose.silent`, `jester.brand.silent`, `jester.consoledebug` and `jester.afk.bypass` were used by the plugin but never registered, so permission plugins could not see them. They are now registered with safe defaults. - **Crash and invalid packets:** packets with non-finite values (NaN / Infinity in position or rotation) are rejected before they reach the movement engine. `CrashC` was rewritten and now cancels the packet and flags in one step. - **KeepSprint cooldown bypass** closed: attack-cooldown tracking now follows the held item and sprint state correctly. - **Held-item tracking:** the selected hotbar slot is tracked correctly after slot changes, respawns and teleports, which removes false flags from items and attack cooldowns. - **Teleports and respawns:** more accurate handling of server teleports and respawns, so players are not setback or flagged right after one. - **False-positive fixes** in the packet-order, sprint, elytra, vehicle, multi-action, BadPackets and Exploit checks, including clients connecting through ViaVersion. - **Blocks and world:** better handling of ghost blocks, dripstone, offset collision boxes and chunk loading. ### ⚙️ Configuration - `messages.yml` moved to config version 4 and gets the new webhook and update messages. Your config and messages migrate automatically and keep your values. Backups are saved as `.bak`. - New file `discord.yml` for the webhook (URL, template, which alerts to send). ### 📌 Notes - **Update PacketEvents.** This version is built against PacketEvents 2.14.1 or newer. Older versions may not work. - 26.x support is new in this beta. If you see false flags on 26.1 – 26.3 clients, please report them with the check name and the client version. - No need to delete your config. It migrates automatically on first start.

## 0.0.5-beta A big accuracy and cleanup release on top of 0.0.4. The main goals were fewer false kicks, protection against mace one-shot exploits, the full packet-order check set, and a config that's easier to read. ### ✨ New - **TeleportHit** check: blocks one-shot mace hits (**MaceKill / MaceDMG**) and **teleport aura**. If a hit comes right after a move no real client can make in one packet, the hit is cancelled, so no damage lands. - **Packet-order checks restored:** **PacketOrderA–O** are back (15 checks). They catch clients that fake actions and send packets in the wrong order. B and C can kick; the rest are beta and alert only. PacketOrderP ships disabled, same as upstream. - **Config versioning:** configs now carry a `config-version`. On update, your file is rebuilt with the new layout and keys, **your values are kept**, and a `.bak` backup is saved. Messages that moved between files keep your customised text. ### 🐛 False-positive & bug fixes - **Low TPS no longer switches checks off:** below `minimum-tps` a check stops completely, and the old default of 19.5 silently switched off **84 checks** during normal TPS dips (crash checks included). The default is now 15. **BadPackets, Crash and Exploit** never pause. - **Old clients:** players on **1.9–1.21.1** standing still (for example at a mob grinder) no longer false-flag the per-tick checks: **NoHitDelay, KillAuraB, AutoClickerB, AutoWeapon, AttributeSwap, TriggerBot** and **NukerA**. - **Momentum:** camel dash, ice boats leaving ice, and TNT or wind-charge launches no longer flag **EntitySpeed, BoatFly** or **Fly**. - **Holding right-click:** holding right-click with rockets no longer flags **FireworkBoost**. - **Building:** drag-click bridging and scaffolding no longer flag **AutoClicker, FastPlace** or **Tower**. - **AutoFish** now detects real fish bites. It used to flag rod PvP instead. - **AutoArmor** no longer flags taking armor off. - **AutoParkour** no longer flags walking up hills or vanilla Auto-Jump. - **CrystalAura** placement detection now works on modern clients. - **BoatClip** no longer flags after a server teleport or a vehicle change. - **Kick-immunity bypass closed:** a well-timed lag spike could make a player immune to kicks for the rest of an offense. - **Violation decay:** time-based decay now applies only to checks that set it. Rare-event checks such as **AutoRespawn** and **AutoTotem** can reach their threshold again. - **Reach** now alerts staff before it kicks. - **Spectate:** `/jester spectate` into another world no longer drops staff into survival. ### ⚙️ Configuration & tuning - **`config.yml` and `messages.yml` reorganised:** checks are grouped by what they detect, each has a short description, and settings are grouped the same way. - **Flag hover tooltip** is now editable in `messages.yml` (`alert-hover`). - **All messages** now live in `messages.yml`. - `toggle-alerts-on-join` now works. ### 📌 Notes - **No need to delete your config.** It migrates automatically on first start, and backups are saved as `config.yml.bak` / `messages.yml.bak`. - Requires **PacketEvents**.

## 0.0.4-beta A large stability, accuracy and configurability pass on top of 0.0.3 — mostly killing false positives, hardening detections, and exposing every setting. Two new checks added. ### ✨ New - **GhostBlock** check — flags placing a block against a position that is air server-side (the ghost-block region exploit). - **GhostItem** check — flags using an item the server doesn't see in the player's hand (inventory desync / fake item). - **Global high-ping guard** — above a configurable ping, movement/combat checks alert but don't kick; packet-integrity checks (BadPackets/Crash/Exploit) still enforce. Judged on live ping, so a lag-switch can't buy kick-immunity. - **AFK via WorldGuard flag** — mark no-AFK zones natively: `/rg flag <region> jester-afk-blocked allow` (region list removed). ### 🐛 False-positive & bug fixes - Throwing egg / snowball / ender pearl / splash & lingering potion / xp bottle / fishing rod no longer leaves a stuck "using item" state that **false-flagged NoSlow & Multitask**. - **Criticals** no longer false-flags players attacking while riding a horse/boat. - **NoSlow** loosened + much faster violation decay — stops false kicks on high-ping players. - **ReachB** hardened: pose-aware eye height (swimming/elytra were ~1 block off), riders skipped, absurd high-ping distances ignored, shield/knockback grace, evidence not wiped by skipped hits. - **KillAuraC** now needs a streak of attacks-while-GUI-open (fixes a container open/close race). - **TriggerBot** now uses real ray-box hitbox intersection instead of a fixed sphere — correct for every mob size (cow/horse/etc.). - **Phase** no longer false-kicks when standing on a shulker box as it opens (still catches real phasing). - **AutoParkour** division-by-zero / bitmask-overflow guard on `window-size`. - Rebalanced the FP-prone rate checks (**AutoClicker, FastBreak, FastPlace, AutoArmor, Multitask**) so butterfly/drag clicking, fast bridging and quick armor swaps don't trip them. ### ⚙️ Configuration & tuning - **Every check is now visible & configurable** in `config.yml` — added blocks for ~100 previously-hidden checks. - **~60 orphaned settings exposed** that the code read but the config never listed: violation **history/database** (SQLite/MySQL), ghost-block/exploit options, Knockback & Reach tuning, ChestStealer/AutoBlock/AutoPot/Explosion, and an **Advanced** section (high-ping API limits, packet-spam threshold, item-usage resets, etc.). - **11 command-response messages** (freeze / tp / cps / kb / setback / rotate / stats / clearviolations) added to `messages.yml` so they're customizable. - Packet-integrity checks (BadPackets / Crash / Exploit) now **enforce** (kick) with commands. - **AFK settings merged** into `config.yml` under `afk:` (separate afk.yml removed). - `Reach` max-violations set to 3; `KillAuraB` `min-targets`, `KillAuraC`/`GhostBlock`/`GhostItem` `min-consecutive`, and `Reach` `extra-reach` are now configurable. ### 📌 Notes - **Back up your config and let it regenerate** after updating — many keys were added/renamed. - Requires **PacketEvents**.

## 0.0.3-beta ### 🐛 Fixes - **Phase no longer false-kicks on shulker boxes.** Opening a shulker box you're standing on used to trigger a Phase setback/kick — the lid's collision change is now exempt. - **ReachB no longer false-flags during knockback.** Taking damage (e.g. while holding a shield) briefly desyncs your position; reach hits within a short knockback window are now ignored. - Removed an experimental aim check that could false-flag legitimate players. ### ⚙️ Changes - **Reach** allowance is now configurable — `Reach.extra-reach` (default `0.3`, i.e. ~3.3-block limit). - **ReachB** flags now display as `ReachB` (instead of `Reach`), so the two reach checks are easy to tell apart. - Plugin-compatibility toggles under `integrations:` are now actually honoured (GSit, WorldGuard, AuraSkills, ItemsAdder, DeluxeCombat). - Wider server support: runs on the same range as the Grim engine (`api-version 1.13`). ### 📌 Notes - Several config keys were renamed for clarity — **back up and let the config regenerate** after updating. - Requires **PacketEvents**.
