Important:

1. Raised the minimum java version to 17 and update all dependencies that were required for java 17.
   This change will allow us to develop and update nullcordx more efficiently, as well as having the latest version of all necessary libraries.
   Compatibility with plugins written in java 8 and above will also remain, as newer versions of java are always backwards compatible with older ones. 
2.  Added the ability to cache license API result.
   You don't have to worry that our API might fail at the worst possible moment. 
   If you run the proxy at least once, then even if the proxy cannot access the API license server, with the help of caching the proxy will still be able to run
3. Now that waterfall does not "update" what will you do? Very simple, waterfall has not been updated for years, except for bungeecord's own updates. NullCordX will continue with strong updates, as always.
4. Fixed and improved modern forge support

New features:

1. Added config migration. Now the configuration will be automatically migrated from old to new versions and you don't need to worry that some parameters were changed after updates.
2. Added chance render layer. You can now set a specific layer to have a rendering chance. This is useful if you want to diversify noise generation.
3. Added group render layer. Now you can specify your own individual layer groups, which will be rendered separately and combined into a single layer.
4. Added copy and paste render layer. Now you can copy the content of the previous layer under a specific ID and then paste the content with that ID anywhere as a separate layer.  Very useful, for example, if you have a list of random images but you want to use a specific copy in the current rendering context.
5. Added the ability to trigger the mode under attack via /antibot trigger command. Compared to the /antibot toggle command, this command simulates the mode triggering as if the proxy actually detected the attack.
6. Added the ability to expect code for framed puzzle. It can be useful when you want the player to first restore the image, and then enter the code from the restored image
7. Updated libdeflate and added a new alternative compression - igzip. Igzip has a faster compression rate but slightly lower compression ratio compared to libdeflate, so it may be the preferred choice for captcha generation
8. Added the ability to configure compression type for cached packets and network compression. You can now separately specify what type of compression and what compression level will be used when decoding and encoding packets on the network and when generating cached antibot packets such as captcha
9. Added /antibot testcompression command. 
   This command allows you to run a small performance test on all available compressors so you can see which one you should use

Changes:

1. Added the ability to send timeout time in the filter using the player's experience bar.
2. Added the ability to reload permissions via /antibot reload command.
3. Added the ability to configure max dirty captcha time.
4. Added the ability to modify framed-captcha spawn distance.
5. Added the ability to display antibot ping data in the logs.
6. Added the ability to generate less than 2 glyphs for code generator
7. Added the ability to set answer prefix for captcha
8. Added the ability to set answer prefix for captcha.
9. Added the ability to download maxmind and proxylist databases from our servers.
10. Added the ability to block client brand by regex.
11.  Added the ability to disable empty chat check.
12.  Added the ability to configure sending of new captcha on fail.
13. Added the ability to random rotate background for glowing circle.
14. Added the ability to enable specific blocks for fall check.
15.  Added the ability for the proxy update check on startup.
16. Added more blocks for fall check.
17. Added more config options for curve layer.
18. Added more flexibility to create examples for the arithmetic generator.

Fixes:

1. Fixed missing description for reset-ping-on-complete option.
2. Fixed missing update for TranslatableComponentSerializer.
3. Fixed missing serialization of Adventure components in plain text.
4. Fixed missing normalization of console commands input.
5. Fixed timeout check in the filter.
6. Fixed ProxyCheck.io risk check if ip was whitelisted.
7. Fixed wrong placeholder for russian translation file.
8. Fixed plugin compatibility (such as Protoclize) with motd cache mode 2.
9. Fixed some memory consumption for windows when using compression.
10. Fixed maxmind database loading behavior.
11. Fixed incorrect reason for kick when exceeding packets or bytes per second.

New features:

1. Added the ability to disable calling the garbage collector after generating a captcha.
2. Added ability to specify frame sizes for framed captcha.

You can now specify an exact frame size instead of a size range.

1. Added ability to limit plugin message amount in the filter.
2. Added the ability to override the execution of a ping check after the check is completed.
3. Added the ability to switch spam and ping attack.

Please note that this changes the message configuration for them, we recommend resetting the configuration or removing specific translation lines so that the proxy regenerates the correct lines.

1. Now the filter will try to spawn the player to the center of the framed captcha correctly, even when the captcha is not symmetrical.
2. The proxy has been updated to the latest version of BungeeCord.

Fixes:

1. Fixed two serious memory leaks when generating and loading captcha from disk.
2. Fixed increased RAM consumption when using fall check.
3. Fixed file captcha cache calculation, which was broken in the last update.
4. Fixed missing hex color for kick reason when connecting to a server.

A new update of NullCordX has been rolled out ->

Big changes in configuration:

1. Migrated to a more updated configuration system from the Elytrium developers.
   Loading and saving configuration should now be more faster and correct.

2. From this moment on, the entire captcha configuration has now been divided into separate configuration files that are located in a separate captcha directory in the nullcordx directory.
   In addition, each type of captcha is now configured separately, with the exception of render layers.
   This means that you can now, for example, configure separate frame sizes for framed-captcha and animated-framed-captcha.
   Most parameters are no longer shared.

3. The structure of the translation configuration has been changed.
   Added absolutely all translation strings from nullcordx.

4. Added minimessage support for all string related configurations.
   Now it's easy to create beautiful gradient or rainbow text in any message, including messages from bungeecord!

5. Now for all configurations where you need to specify the path to files, the ability to specify a directory has been added.
   The proxy will load all files in the directory.

6. Added the ability to parse the subnet mask for IP addresses.
   Now you can specify for example 127.0.0.0/24 to include addresses from 127.0.0.1 to 127.0.0.255 in the list.

7. Warning! There has been a bit of cleaning done on most configs, some options have been moved or merged, so please be sure to check out the configs and tweak them!
   Loading old configurations may break existing configurations.
   Don't forget to make a backup copy of your configurations to configure the new configuration the same way!

Captcha optimization and improvments:

1. Captcha generator has been optimized.
   Now the captcha is generated 2 times faster and takes up almost 2 times less memory space.

2. Added file cache for fonts.
   Now the proxy will load much faster, since it will not have to redraw the fonts every time.

3. The code generator is now a separate render layer.
   The generator was divided into 3 types of layers - code, arithmetic and number spelling.
   You can set up and use any of the generators or use them together in one captcha.
   Or create a second template for the generator that only draws, for example, numbers with a certain font.

4. Added 2 more default fonts - dialog and dialog-input.

5. Added the ability to make default fonts italic or bold.

6. Added random render layer.
   It allows you to draw one of the layers specified in it randomly.
   This can be useful, for example, for random render of code and arithmetic.

7. Added the ability to use only the color palette from version 1.8 of the game.
   By default, 4 color palettes are used for more accurate colors, but this captcha takes up some memory space.
   Using only one palette can save almost 4 times memory space, however, image colors may be poor.

8. Now the captcha generator will forcefully terminate its work when reloading nullcordx.

Antibot improvments:

1. Added the ability to configure any number of custom modes.
   For example, you can create a mode called test which will contain only framed-captcha and then switch it with the command /antibot check custom false test (where false is whether to switch the mode for bedrock players)
   Thus, you can create any modes in advance and switch their commands for different situations.
   (Don't forget to enable custom mode with the /antibot toggle custom command so that the filter uses custom checks.)

2. Added the ability to specify risks for proxy checks.

3. Added ASN check.
   Now you can block the specified hosting providers from which bot attacks are usually carried out.

4. Added a new proxy service - Vpn Api.

5. Now country and asn check will periodically update the database while the proxy server is running.

Motd improvments:

1. Added the ability to send the same game protocol for all versions.

2. Added ability to set online placeholders for custom motd.

3. Added protocolize support for motd cache type 2.

Other improvments or fixes:

1. Added more information about which components are loading during the nullcordx initialization process.

2. Added api for anti-proxy, anti-asn and anti-country.

3. Added info about dynamic dns updating.

4. Fixed sometimes wrong dithering for captcha.

5. Added ability to configure pooled or unpooled ByteBufAllocator for cached packets.

6. Fixed velocity forwarding mode.

7. Fixed guava and some other dependency relocation.

8. Added api to override isNeedCheck for antibot.

9. Added pagination for whitelist command.

10. Added /antibot banlist command with pagination.

11. Added HaProxyConnectionInitEvent event.

12. Fixed entity remove packet for 1.17 client.

13. Fixed wrong description and configuration for tcp fast open.

14. Fixed advanced ping check mode checking.

15. Added ability to disable PlayerHandshakeEvent event.

16. Added UserFailedCheckEvent event.

17. Added ability to hide server switching log.

18. Fixed /antibot servers reload command.

By the way, we have a fork of Paper that you can purchase as an addon to this resource!

• Fixed and improved the feature of blocking the IP address when an exception occurs during an incoming connection
• Fixed plugins like FastLogin dependency by returning the unused field "stats"
• Fixed issue where bungeecord config could change server names to lower case
• Fixed incorrect "fall-and-hand-captcha" pass condition
• Fixed situation when "connect-to-filter only-on-attack" was enabled, the many check was triggered
• Fixed incorrect entity frame hitboxes for clients 1.12.2 and below
• Fixed null forward secret and null game version in waterfall.yml config which could lead to unexpected behavior
• Removed unnecessary decoding check when checking nickname length for dowstream connection
• Implemented the ability to specify the path to the file on the current host for the proxy scraper feature
• Now for geyser players, the fall check will always be simplified due hard-emulation for packet translation
• Now The /antibot cpu command will now show the amount of RAM used, including direct memory and heap memory
• Now you can specify at what specific type of exception to block the IP address
• Now the antibot will try to send all the necessary packets to the client improving even more vanilla-check
• Now the splash is more correctly replaced when entering a captcha message
• Improved Query handler replacing redundant cache with Caffeine
• Improved fall check added even more blocks and some other checks to new vanilla-bots
• Improved the API and some abstractions have been moved to other packages. Now it is possible to create and register your own anti-bot checks
• Improved Name blacklist by adding name-regex, and now this check is considered as a template and for it to work you need to add it to modes
• Modified the system of conditions for antibot templates has been rewritten.Templates can now, depending on the failure or success of the check, kick, finish, start the next check, or start any specified check. This allows you to flexibly configure in which situation what check the antibot should perform, depending on how the player passed it.
• The proxy is now loaded asynchronously on boot, which will allow much faster opening of a listening port for bungeecord without having to wait for all the nullcordx components to load. This also fixes the situation when after executing the command to restart, it was impossible to use any commands during the boot
• Added the ability to cache all images and gifs to disk for fast loading when the proxy is enabled
• Added the ability to adjust the quality of image resizing
• Added a more correct gif decoder for correct reading of any gif files

• Added the ability to apply render layers for glowing circle background
• Added the ability to disable player caching when the "connect-to-filter-only-on-attack" mode is enabled
• Added the ability to randomly shift glyph height for captcha
• Added the ability to cache all types of captcha to disk .Now, between proxy restarts the captcha will not be regenerated, instead, the captcha will be loaded from disk
• Added ability to set trigger chance for render layer rotation
• Added render layer mirror
• Added the ability to turn debug mode on and off automatically during an attack
• Added attack end events on the API and modified it
• Added new pick-captcha (Most advanced anti-bot) system the principle is similar to recaptcha or hCaptcha, you need to click on all the images where an abstract object is displayed and then enter into the chat if there are none left. We're the first one adding this system, same like Framed-captcha

(GEYSER "FIX" without disabling nothing)

Partially fixed the situation when the proxy kicked the player's geyser with the disable compression parameter enabled.

This still won't work for a filter because all packets for a filter are always cached and compressed.

If you store an uncompressed copy, the memory consumption will increase by at least 3 times, for this reason you still need to disable this option.
