 # Maintenance Changelog
 This file contains update logs for this project. The top may contain a `Unreleased` section, gathering update logs for a future update during development.
 
+---
+## 4.3.0 - September 17th 2024
+## Unreleased
+### Changed
+* Added alternative player count and player list hover message for when endtimers are running, similar to the existing ping messages setting. They are disabled by default and can be found in their `player-count-message` and `player-list-hover-message` config sections
+* All timer commands now accept durations like `2h30m`, `1h30m5s`, or `90s`. The default behavior without units will still be in minutes
+  * The language defaults will not automatically update, you might want to manually update the command help strings or just delete your language file
+* Slightly reorganized the configuration file (it will be automatically migrated on startup, but new sections will be slapped at the bottom of the file)
+* The `fallback` field now also null values next to an empty array for disabling the feature
+* Updated language files from [Crowdin](https://crowdin.com/translate/maintenance)
+
+### Fixed
+* Fixed the `/maintenance dump` command
+* Fixed the original player sample not being cleared in Velocity
+* Velocity: Fixed the console getting broadcasts twice
+* Velocity: Don't log legacy color codes to the console
+* Paper: Fixed the player count messages on Paper 1.21
+---
+## 4.2.1 - May 17th 2024
+### Changed
+* The proxied maintenance status is now also shown for forced hosts (thanks to alec-jensen)
+* Offline player fetching improvements (thanks to EpicPlayerA10)
+  * Added the setting `fallback-to-offline-uuid` to use offline player uuids in maintenance whitelist commands (defaults to false)
+* Maintenance now skips the plugin remapping process on 1.20.5+ Paper servers
+* Small optimizations
+* Updated language files from [Crowdin](https://crowdin.com/translate/maintenance)
+  * Massive thank you to all the contributors! These include: vortix22, xdalul, CodeZhangBorui, jesusskye, Doc94,

+    raysetratyboy, Kolja07, and rikunightcore
+---
+## 4.2.0 - September 17th 2023
+### Changed
+* Velocity/Bungee: Added `commands-on-single-maintenance-enable` and `commands-on-single-maintenance-disable` config options to define commands to be executed after maintenance has been toggled on a proxied server
+  * Commands inside the `all` list will be executed for any proxied server, but you can also define commands for specific servers by adding arrays with the server names as keys
+  * You can use the placeholder `%SERVER%` in commands to be replaced with the server name
+* Start-, end-, and schedule timers for proxied servers now also include the server in the feedback message
+* Updated language files from [Crowdin](https://crowdin.com/translate/maintenance) (including new language files for Danish, Japanese, Korean, and Hungarian)
+---
+## 4.1.0 - April 17th 2023
+### Changed
+* Added config option `enable-playercounthovermessage` to be able to toggle the player count hover message
+* Removed platform specific command aliases (e.g. `maintenancevelocity`)
+* Translations
+  * Moved translation editing to [Crowdin](https://crowdin.com/translate/maintenance)
+  * Added Turkish translation file (thanks to Proomp)
+  * Added Swedish translation file (thanks to Sup33r)
+  * Added Ukrainian translation file (thanks to Mrlucke)
+  * Added Japanese translation file (thanks to yu-solt)
+* Added bStats metrics to Velocity and Sponge modules
+
+### Fixed
+* Fixed disabling the `enable-pingmessages` setting not working on Paper servers
+* Fixed variable replacement in messages with gradients
+* Fixed the message for cancelling proxied server timers not replacing the server argument
+* Setting `enable-pingmessages` to `false` no longer disables custom player and player hover messages
+---
+## 4.0.1 - April 17th 2022
+### Fixed
+* Fixed the config header sometimes breaking the config on upgrading/saving
+---
+## 4.0.0 - March 17th 2022
+### Changed
+* Added support for hex colors in messages and replaced the component parsing with adventure-minimessage
+  * This means that section symbols (`§`) are no longer the intended/supported format
+  * You can use the following page to edit and preview formatted text: https://webui.adventure.kyori.net/
+  * You can find full documentation on the format (including normal colors and formatting, rgb, click/hover events, and more) here: https://docs.adventure.kyori.net/minimessage/format
+  * Your config and language file will be updated to the new format automatically, you won't have to change anything manually!

+* Updated Sponge module to SpongeAPI v8 (Minecraft 1.15+)
+* Changed `%NEWLINE%` replacement to `<br>`

+* Added Polish translations (thanks to Slasherss1)
+* Updated French translations (thanks to Aurelien30000)
+* Updated Spanish translations (thanks to Jaximo)
+* If you were using the MaintenanceAddon, you need to update it to [version 1.2.0](https://github.com/kennytv/MaintenanceAddon/releases/tag/1.2.0)
+### Fixed
+* Fixed missing language key warning for the scheduletimer command
+* Fixed typo in `singleServerMaintenanceListEmpty` default language string
+* Fixed typo in language key `whitelistEmpty` in the German language file (by Ceddix)
+---
+## 3.0.7 - August 17th 2021
+### Changed
+* Bungee/Velocity: `/maintenance add <name>` now works for offline players as well
+* Added config options `commands-on-maintenance-enable` and `commands-on-maintenance-disable` to define commands to be executed after maintenance has been toggled
+* Added config option `enable-pingmessages` to can change whether a custom maintenance motd should be displayed during maintenance
+* Added language fields `scheduletimerBroadcast` and `singleScheduletimerBroadcast` with the variables `%SERVER%`, `%TIME%`, and `%DURATION%` instead of using the normal starttimer broadcasts
+### Fixed
+* Fixed SQL loading issues on some platforms
+* Fixed missing language key warning for the debug command
+* Velocity: Fixed the update message
+---
+## 3.0.6 - February 17th 2021
+### Changed
+* Updated the Velocity version to be compatible with Velocity 1.1.0 (use Maintenance 3.0.5 if you use an older version of Velocity)
+* Added `maintenance schedule <minutes> <duration> command`
+  * This starts a timer for maintenance to be enabled, after which another timer will be started to disable it again (in contrast to `starttimer` and `endtimer`, which each only do one of)
+  * On proxies, you can use `maintenance schedule [server] <minutes> <duration> command` to schedule maintenance on a proxied server
+* Added command alias `mt` for the Maintenance command
+* Added secret argument to the whitelist add command: You can use `maintenance add <uuid> <name>` to add offline entries per command
+* The maintenance's base command is now properly registered with a permission on each platform, so that it is excluded from tabcomplection to unauthorized players
+* Some improvements to the French language file (thanks to @Aurelien30000)
+* API addition: Added MaintenanceReloadedEvent
+  * If you are using the MaintenancePlaceholderAddon, you need to [update it to 1.1.0](https://github.com/KennyTV/MaintenanceAddon/releases)
+### Fixed
+* Fixed not setting custom singleserver kickmessages throwing warnings
+* Bungee: Fixed linebreaks in the playercount hovermessage for 1.16+ clients
+---
+## 3.0.5 - June 17th 2020
+### Changed
+* The plugin identifiers are now `Maintenance` instead of the previous `MaintenanceSpigot` and `MaintenanceBungee`,
+ and `maintenance` instead of `maintenancesponge` and `maintenancevelocity`
+  * The plugin directory will automatically be renamed accordingly when starting the server
+  * If you are using the MaintenancePlaceholderAddon, you need to [update it to 1.0.3](https://github.com/KennyTV/MaintenanceAddon/releases)
+* Bungee/Velocity: The `fallback` field can now also be set as a list to define multiple fallback servers
+* Bungee/Velocity: Added language fields to choose custom kickmessages for individual proxied servers
+  * See [**HERE**](https://github.com/KennyTV/Maintenance/wiki/Configuration#language-file) for an example setting
+* Added Chinese language file (thanks to Spigot user yeban)
+* Added Italian language file
+* Updated Russian language file (thanks to Spigot user En_0t_S)
+* Removed automated config migration from 2.x->3.0
+  * See [**HERE**](https://github.com/KennyTV/Maintenance/wiki/Updates#updating-from-2x) on how to do that manually - virtually noone should be using such old versions anymore
+### Fixed
+* Fixed the `use-ssl` option being inverted
+* Fixed disabling the playercount-message still hiding online/max players
+* Fixed config parsing with multi line strings
+* Bungee: Fixed compatibility with other motd changing plugins using the 'HIGHEST' ping listener priority
+---
+## 3.0.4 - March 17th 2020
+### Changed
+* Bungee/Velocity: Added config option `waiting-server` to send players to a waiting server when global maintenance is enabled (instead of kicking them)
+* Bungee/Velocity: Added config option `use-ssl` in the `mysql` section to disable SSL connections
+* Added Russian language file (thanks to Spigot user En_0t_S)
+* Updated missing translations in Portuguese language file (thanks to Spigot user JoaoPinto)
+* Updated bStats metrics
+### Fixed
+* Fixed singleserver timers using input as seconds instead of minutes (by mxs42)
+* Fixed singleserver timers broadcasting globally
+* Fixed language updating with an unknown/self-translated language file
+* Fixed Velocity server autocompletion in the maintenance command
+---
+## 3.0.3 - September 17th 2019
+### Changed
+* Bungee/Velocity: Added `maintenance.singleserver.bypass.<server>` permission to give individual bypasses for proxied servers (`maintenance.bypass` will still bypass everything as the super-perm)
+* Added the messages of the help command into the language files
+* Added config option `kick-online-players` to disable the kicks when maintenance is enabled (new connections will still be blocked)... not sure why you'd want that, but you can :p
+* The language file will now be automatically updated as well, so no need to delete and recreate it anymore, yay!
+* Updated missing and new translations in French language file (thanks to Spigot user Zendrique)
+* Updated missing and new translations in Spanish language file (thanks to Spigot user Vixo_Ulises)
+### Fixed
+* Bungee/Velocity: Fixed the join-notifications being sent twice if both global and server maintenance are enabled, as well as when just a server has maintenance in some cases
+* Bungee: Fixed players being kicked *after* the initial connection and thus triggering a join and leave message before being kicked
+* Bungee: Fixed the kickmessage not being displayed in some cases
+* Paper: Fixed the playercount message not being displayed on Paper servers with ViaVersion
+* Paper: Fixed the motd not being changed at all on Paper servers with ProtocolSupport (-> ProtocolLib listener used, since ProtocolSupport does not fire Paper's ping event)
+* Fixed the config autoupdater when the config contained strings broken over multiple lines
+---
+## 3.0.2 - May 17th 2019
+### Changed
+* Added config option `timerspecific-pingmessages` to have specific pingmessages shown when endtimers are run
+  * You can also set them ingame by using `/maintenance setmotd timer <index> ...` instead of `/maintenance setmotd <index> ...`, along with `/maintenance removemotd timer <index>` and `/maintenance motd timer`
+* Made dumps a little prettier
+* Support Sponge 8.0.0-SNAPSHOT
+* Support latest text/Velocity (now only supports Velocity builds from May 7th upwards)
+---
+## 3.0.1 - April 17th 2019
+### Changed
+* Created an addon to have PlaceholderAPI placeholders on Spigot when running the Maintenance plugin on Bungee (see [**here**](https://github.com/KennyTV/Maintenance/wiki/MaintenanceAddon))
+* Spigot version: If running on Paper 1.12.2 or higher, ProtocolLib will not be needed anymore
+* The universal jar now only includes Bungee and Spigot (whereas before Sponge and Velocity as well) and has been further minimized in size
+  * To use the plugin on the other platforms, use the `MaintenanceSponge.jar` or `MaintenanceVelocity.jar` respectively
+* Added config option `continue-endtimer-after-restart` to have endtimers continued, even if the server restarts during its runtime
+* Added custom eventsystem to the API
+* Removed bStats metrics from Sponge module
+### Fixed
+* Actually fixed compatibility to other plugins using the same MySQL library (such as LuckPerms) in the Bungee version
+* Fixed an issue with executing the maintenance change with MySQL enabled on connected proxies
+* Fixed an occasional error on pings of non clients in the Spigot version
+* Fixed 1.13 clients on sub 1.13 servers not showing the playercountmessage in the Spigot version
+* Minor fixes/changes to Spanish and Portuguese language files
+---
 ## 3.0 - February 17th 2019
 ### Changed
 * This plugin now also supports the platforms Sponge and Velocity!
