Mythras 1.31.2 Latest

  • Fixed no more false Timer and Protocol [Transaction] alerts right after a teleport on a slow connection (high ping). On a slow line the new chunks fill the connection and Mythras' pings wait behind them for many seconds: this was flagged as "ping unanswered for 10 s", the late answers as "answered ping that was never sent", and the client catching up afterwards as Timer. Now a ping that went out among chunks may wait up to 30 seconds, a late answer to a ping Mythras stopped waiting for is accepted, and Timer counts the time those pings are waiting as lag. A Disabler that holds the pings back is still flagged after 10 seconds (or 30 while new chunks keep loading), and Timer Pulse and Boost are still caught.
  • Fixed changes you made to config.yml while the server was running were overwritten as soon as a setting was changed from the game (/ac settings, /ac lang) or from mythras.eu. Mythras now reads the file again before saving, so your edits stay.
  • Fixed lag-backs now really stop movement cheats. The safe position the player is sent back to moved along with the cheat while a check was still collecting evidence and in the few unchecked ticks after each lag-back, so a Fly, Step or Speed gained a little ground with every lag-back and the setback looked like it sometimes did nothing. Now a move a check doubts, and the moves right after a lag-back, never become the safe position: a Fly that tries to climb stays where it started.
  • Fixed CrystalAura no longer flags "broke crystal in the same tick it appeared" on players who place and break crystals by hand very fast: clicking on the obsidian right before counts as clicking, like a missed swing. Crystals broken with a human delay also lower the count again. AutoCrystal and break-on-spawn auras are still flagged.
  • Fixed fewer false Blink alerts when the game freezes for a moment (another program or a second client starting on the same PC): a frozen vanilla client catches up at most 10 ticks, Blink delivers every tick it held, so a long freeze followed by 10 ticks or fewer counts half. Blink used again and again is still flagged.
  • New AutoSwitch [OneTick] catches one-tick silent switches: selecting a hotbar slot, using it in the same tick and selecting the old slot again the next tick (LiquidBounce SilentHotbar, used by ElytraFly Firework, auto pots and auto gapples). By hand, the key, the click and the key back take several ticks.
  • New AutoTotem [Reaction] flags the first inventory click or hand swap less than 90 ms after the client received the totem pop (ping cancels out). Auto totems with a delay of a tick or two (LiquidBounce Offhand) no longer slip under the same-tick rule.
  • Improved Inventory [Steal] also catches ChestStealers with default random delays (LiquidBounce: start after 1-2 ticks, a click every 2-4 ticks): when the first click comes within 125 ms of the container appearing and every click lands on a whole game tick. A person's clicks come from the mouse at any point of a frame.
  • Improved Backtrack flags a round trip 90 ms higher while fighting (was 150 ms), so the LiquidBounce default delay of 100-150 ms is caught. Configs still on the old default follow the new one by themselves.

Mythras 1.31.1

  • Improved /ac info on a Bedrock player (Geyser/Floodgate) now shows "reduced checks (Bedrock checks)" in yellow instead of a red "NOT checked": Bedrock players are checked, by the checks listed in bedrock.checks (Reach, FastPlace, FastBreak, Crash by default). The new line is added to your message files by itself, in every language.
  • Tested with a Bedrock player joining through Geyser 2.12.1 and Floodgate: walking, jumping, falling, fighting at 2.6 and 3.4 blocks, touch aim and taking knockback give no alert; a 5.5-block Reach is flagged and deals no damage; Anti-ESP hides players behind walls from Bedrock players too.

Mythras 1.31.0

  • New KillAura [SilentAim] catches "silent aim" and "silent aura" modules, such as the Silent Aim of Vape V4 and Prestige Client. They leave your camera where you look and turn you toward the target only for the tick of the hit, then straight back: the server sees a snap of 10 degrees or more onto the target and an equal snap back the very next tick. A player who flicks onto a target keeps following it, so Mythras flags 4 such exact returns within 10 hits.
  • New AutoTotem [HotbarSwap] catches auto totems that refill the off hand from the hotbar without opening the inventory (Prestige "Auto totem" style): select the totem's slot, swap hands and select the previous slot again, all in the same tick right after a totem pops. By hand that takes three key presses, which never fit in one 50 ms tick.
  • Tested on Paper 1.21.1 and 1.21.4 with bots copying both modules: flagged after 4 hits and on the first totem pop. A player who flicks onto the target and then looks around, and a totem swap done with the keys, get no alert; the full test suite passes.

Mythras 1.30.0

  • New Velocity [AirStop] catches velocity cheats that take the knockback and then cancel it in mid-air, such as Vape V4's Velocity. They let the first tick of the knockback through (so the existing Velocity tests saw a full 100%) and a few ticks later drop the horizontal speed to zero while still in the air, which no real client can do: in the air a player keeps 91% of their speed every tick unless a block stops them. Works for every client version, including 1.8.9 players joining through ViaVersion.
  • Improved KillAura [Pattern] and the new [AirStop] were tested against logs from a real Vape V4 client on a 1.21.4 server. Vape's fixed 4 clicks-per-second rhythm is not flagged on purpose: at that pace the server cannot tell it apart from a steady human player, and Mythras does not risk false bans.
  • Tested on Paper 1.21.1 and 1.21.4: the Vape-style velocity is flagged on every knockback, a legit player taking hits while walking and jumping gets no alert, and the full test suite passes.

Mythras 1.29.1

  • Fixed KillAura [Pattern] missed triggerbots and "ghost" auras such as Prestige Client's. They attack the moment the sword cooldown is full but only while you are in range, so every pause to chase the target restarted the count and a normal fight never reached the 20 hits needed. Pauses without swings now keep the count, and a player whose hits all land within 1 tick of the full cooldown (the others only after a pause, never a few ticks late or early, never a swing at the air) is flagged.
  • Tested with a Prestige-style triggerbot (human aim, hits on the cooldown, fights broken off every 8 hits): flagged within 30 hits. A skilled legit player timing the cooldown by hand, three 50-second fights: no alert. The full test suite on Paper 1.21.1 and 1.21.4 passes as before.

Mythras 1.29.0

  • New Prediction now also checks players on Minecraft 1.21 and 1.21.1 (joining directly or through ViaVersion). These clients don't tell the server which keys they press or where each tick ends, so the light speed hacks only Prediction sees went unnoticed on them: LiquidBounce Speed "Intave14Fast", "Verus" and "Matrix7" while turning, "HypixelBHop" zig-zagging. Mythras now takes each of their movements as one tick and tries every key combination, so only movement no real input explains is flagged.
  • Improved nothing to set up: the update works on its own on every server with 1.21-1.21.1 players.
  • Tested on Paper 1.21, 1.21.1 and 1.21.4 with 1.21.1 and 1.21.4 players, over 190 legit and cheat scenarios each: all 19 LiquidBounce Speed modes, plus wind charges, teleports, knockback, stairs and walking along walls without a single false alert.

Mythras 1.28.0

  • New safer updates. Every new version now runs on our own test servers first and reaches yours only after it has passed there, so a broken build can never land on your network overnight.
  • Improved the loader (1.3) checks for updates with your license key. When you report a problem we can send a fix to your server alone and confirm it works before everyone gets it.
  • Improved updates keep installing themselves at your next restart, verified against our signature, exactly as before: nothing to do on your side.

Mythras 1.27.2

  • Fixed on Velocity, cross-server alerts were silently dropped when the proxy had no permission plugin (Velocity has none built in).
  • Improved MythrasProxy 1.1 learns who your staff are from each Mythras server (mythras.alerts), so network alerts, punishments and the "click to go to that server" link reach them with no extra setup on the proxy. Download MythrasProxy 1.1 from the download page.
  • Tested on Velocity and BungeeCord: network alerts, network bans ([netban]) and banned players refused at login on every server.

Mythras 1.27.1

  • Fixed on Folia, KillAura's aim-lock detection and Reach compared each hit with where the target was one tick earlier, so many auras went unnoticed. Folia servers now catch them exactly like Paper servers.
  • Tested on Folia end to end: X-Ray detection reports hidden diamonds dug straight to, and the Anti-XRay add-on keeps ores hidden from X-Ray clients.
  • Fixed stopping a Folia server no longer prints a scheduler error in the console.

Mythras 1.27.0

  • New LiquidBounce Speed "Intave14Fast" is detected. It adds only 2-4% per jump to stay under per-tick limits; Mythras now adds the gain up over the whole jump.
  • New LiquidBounce Step "BlocksMC" is detected, including the trick that hides its height cut inside a burst of delayed packets.
  • New LiquidBounce Timer "Pulse" and "Boost" are detected. These modes run the game slower to "save" time and spend it later in a burst; saved time is now accepted only when your ping really went up.
  • Improved we replayed all 19 LiquidBounce Speed modes on test servers. Every mode that gives an advantage is caught; the only ones left unflagged move exactly like a normal bunny-hop.
  • Improved omni-sprint (LiquidBounce Sprint "Omnidirectional", sprinting backwards or sideways) is reported up to four times a second, so your staff see it at once.
  • Fixed no more false ElytraFly alerts when you click several firework rockets in a row, fly straight up, dive, or play with a high ping.
  • New /ac discord test sends a test message to your Discord webhook and tells you exactly what is wrong: deleted webhook, incomplete URL, discord.enabled still false, or alerts turned off.
  • Licenses a key now works only from the IP addresses registered on it. A key without one is refused, and the console prints the exact IP to give (in the setup link on mythras.eu or to our staff on Discord).
  • Tested on every supported version: Paper 1.21 to 1.21.11, 26.1.2, 26.2 and Folia, with over 240 legit and cheat scenarios each.
Show older versions

Mythras 1.26.0

  • New automatic updates. The loader checks for a new Mythras at startup and every 6 hours, downloads it, verifies it against our signature (a modified file is thrown away) and installs it at your next restart. No more manual downloads.
  • Your staff are told in game when a new version has been downloaded and will install at the next restart.
  • Prefer to update by hand? Set auto-update: false in plugins/Mythras/license.yml.
  • One last manual step: if your Mythras is older than 1.26.0, replace it by hand once; every later version arrives by itself.

Mythras 1.25.4

  • The console shows your plan and add-ons at startup and after mlicense (e.g. "plan PRO + Anti-XRay").
  • An add-on bought without choosing a key goes on your Pro key.

Mythras 1.25.3

  • The key limit counts machines, not servers: on the machine (IP address) of your key you can run as many servers as you like.

Mythras 1.25.2

  • An old config.yml is cleaned at startup: metrics/bstats-id and update-checker.modrinth-project are removed; only bstats: true|false and update-checker.enabled stay.

Mythras 1.25.1

  • Folia is supported on Free too.
  • Fixed no Timer after a freeze longer than a second (connection stall).
  • Fixed no Speed/Flight when a knockback or an explosion arrives in a different tick (crystal spam, fights with lag).
  • Fixed no CrystalAura for 1.21-1.21.1 clients standing still; no Speed when an elytra glide starts again after a teleport.
  • Improved Criticals "Jump" from the first jump after joining; Jesus pulls a water-walker back every few steps.

Mythras 1.25.0

  • Anti-XRay and Anti-ESP (with Anti-StorageESP) are add-ons paid once and kept for ever, also on Free servers.
  • /ac license shows your plan and add-ons.

Mythras 1.24.0

  • Two plans: Free and Pro (everything that was Enterprise), paid with PayPal on mythras.eu.
  • Anti-XRay and Anti-ESP turn on without a restart when you buy them.
  • Keys bought before (Base, Pro, Enterprise) are now Pro and keep their servers.

Mythras 1.23.0

  • The answers you give in the setup link on mythras.eu configure the plugin by themselves.
  • A key can be locked to your server's IP address.

Mythras 1.22.0

  • Blink catches holds from 0.4 s.

Mythras 1.21.2

  • NoSlow also catches NoSlow modules for cobwebs, soul sand and honey blocks.
  • Fixed no BadBreak, BadPlace, Phase or FreeCam alerts when the server refuses a break or a placement (spawn protection, claims).
  • Fixed no Jesus alert when walking out of the water onto a bank at the same height.

Mythras 1.21.1

  • Fixed no Blink alert when a client (e.g. Lunar) freezes for a moment after joining.

Mythras 1.20.0

  • Mythras rebuilds the world as each player's client sees it: Reach and KillAura are stricter on moving targets, without lag false alerts.
  • Prediction also judges movement next to slabs, stairs, fences and panes.

Mythras 1.19.0

  • New Prediction check: replays vanilla movement with the keys the player presses and flags what no input explains (light speed, AirStrafe, "legit" BHop).

Mythras 1.18.0

  • Anti-ESP, Anti-XRay and Anti-StorageESP also on Folia.

Mythras 1.17.0
