• Server config lists automatically remove the redundant /automodpack/host-modpack/ prefix
• Connection handshake updated to work with playit.gg

Full changelog: v4.0.0-beta42...v4.0.0-beta43

• Fixed a rare Neo/Forge crash caused by using a hyphen instead of an underscore in modId
• Fixed dependency resolution for mods split with the forceCopyFilesToStandardLocation option
• Fixed some certificate edge-cases by @gesterom in #405
• Updated Russian localization by @VideoGamerRUS in #423

New Contributors

• @gesterom made their first contribution in #405

Full Changelog: v4.0.0-beta38...v4.0.0-beta39

What's Changed

• Added 1.21.6 compatibility.
• Added forceCopyFilesToStandardLocation option to the server config. It's a list of files that client will be forced to load from standard directory. By default most mods are loaded from separate automodpack directory, this list specifies files which will be copied to e.g. standard mods folder. This will break seamless updates! Use only when you have really good reason for it. Configuration works exactly the same way syncedFiles does.
• disableInternalTLS doesn't require loopback address anymore, although its still very much recommend.
• localAddressToSend got removed, it was useless.
• portToSend behavior was slightly changed (see wiki). Now its more similar to how it worked in beta 36. Using reverse proxies will require it to be configured but connections though e.g. playit.gg should work out-of-the-box.
• Auto downgrading to versions lower than this (4.0.0-beta38) is now prevented to avoid potential security issues from older versions.
• A lot of boring internal build script changes.
