 # Changelog
 
-## v1.7.1
-### Fixed
-* YAML parser has been updated to fix some strange issues
-
-### Added
-* Added `Force Outgoing IP` option for servers to ensure outgoing traffic uses the server's IP address
-* Adds an option to control the level of gzip compression for backups
-
-## v1.7.0
-### Fixed
-* Fixes multi-platform support for Wings' Docker image.
-
-### Added
-* Adds support for tracking of SFTP actions, power actions, server commands, and file uploads by utilizing a local SQLite database and processing events before sending them to the Panel.
-* Adds support for configuring the MTU on the `pterodactyl0` network.
-
-## v1.6.4
-### Fixed
-* Fixes a bug causing CPU limiting to not be properly applied to servers.
-* Fixes a bug causing zip archives to decompress without taking into account nested folder structures.
-
-## v1.6.3
-### Fixed
-* Fixes SFTP authentication failing for administrative users due to a permissions adjustment on the Panel.
-
-## v1.6.2
-### Fixed
-* Fixes file upload size not being properly enforced.
-* Fixes a bug that prevented listing a directory when it contained a named pipe. Also added a check to prevent attempting to read a named pipe directly.
-* Fixes a bug with the archiver logic that would include folders that had the same name prefix. (for example, requesting only `map` would also include `map2` and `map3`)
-* Requests to the Panel that return a client error (4xx response code) no longer trigger an exponential backoff, they immediately stop the request.
-
-### Changed
-* CPU limit fields are only set on the Docker container if they have been specified for the server — otherwise they are left empty.
-
-### Added
-* Added the ability to define the location of the temporary folder used by Wings — defaults to `/tmp/pterodactyl`.
-* Adds the ability to authenticate for SFTP using public keys (requires `Panel@1.8.0`).
-
 ## v1.6.1
 ### Fixed
 * Fixes error that would sometimes occur when starting a server that would cause the temporary power action lock to never be released due to a blocked channel.
