Component Versions

Core: 4.2.6
HTTP API: 6.4.1
DreamMaker API: 5.2.1
Web Control Panel: 0.4.0
Host Watchdog: 1.1.0

Patch 5

Core

  • Fixed a deployment crash that could occur when posting GitHub comments. (#1013)

  • Added automatic login refresh functionality to IServerClient (#1017)

Patch 4

Core

  • The patch includes a refactor to the job system that may fix the issue with deployments stalling for long periods of time. (#1010)
  • The watchdog should no longer enter crash loops when shutting down the server. (#1010)

Patch 1

Core

  • Fixed an issue where the Live game folder may get cleaned during instance startup on Windows. (#987)
  • Fixed instance cleanup having the potential to run past the servers lifetime. (#987)
  • Added a DreamDaemon launch error if the BYOND pager is detected to be running on Windows. This causes a stall when starting .dmbs. (#987)

  • A hard limit of 1000 UTF-8 characters have been added to most strings in models. (#920)
  • Improved server-side validation of many models. (#920)
  • It's no longer possible to set rights enums to invalidly high values. (#920)
  • It's no longer possible to create multiple users with the same system identifier. (#920)
  • Fixed chat bot names conflicting with those in separate instances. (#920)
  • Added configurable limits for the maximum number of users and instances in the server. (#920)

  • Fixed the workarounds for trusted mode .dmbs that regressed. (#935)
  • CompileJob models now have the received DMAPI version in their dataset. (#935)

  • Reduced memory requirements while sending BYOND topics. (#956)

Initial Release

Whats New:

  • Agnostic HTTP API: The replaces the WCF service calls used in TGS3. This helps avoid Windows vendor lock-in and get away from the SOAP API that literally no one understood (not even me). With it, it's much easier to expose TGS to the internet, all you need is a HTTPS reverse proxy in front of it. A rundown of the new API exists here: https://tgstation.github.io/tgstation-server/api.html.
  • Granular Access Controls: Windows users are no longer (required to be) the basis for authentication to the server. We now have database-backed users as a login option. These use a combined Basic/JWT authentication scheme with industry standard password hashing and salting. Users are fully customizable and can be given granular access to every bit of the server via the new permissions system. From changing the BYOND version, to test merging a PR, to restarting the server, every action may now be granted or revoked on a per user basis.
    • Limitation: Users can be disabled but not deleted.
  • Proper Long Running Operation Support: Server actions take a long time, from a git pull to a DreamMaker compile. TGS now internally allows for them to be run in parallel with each other and provides an audit record via the database. This is an improvement over the old system where connections had to be held open for the duration of operations.
  • Database Backend: TGS requires an SQL database to operate. This allows for much better concurrency and is just overall much cleaner than the old single json file storage blob per instance.
    • Limitation: There is a one-to-one relationship with a TGS server and a database. DO NOT SHARE TGS DATABASES.
  • Linux/Docker Support: TGS4 is Linux and docker compatible. (Note this does not mean that rust-g and BSQL work out of the box, they must be compiled using event scripts like PreCompile.sh).
    • Limitation: TGS4 has a dependency on the native library libgit2 which is known to cause issues on Linux. The binaries distributed with TGS are kept up to date with the upstream repository, but out of the box Linux support can't be assured in every environment. Docker is guaranteed to always work, however. See the repository for the distributed binary here: https://github.com/libgit2/libgit2sharp.nativebinaries.
    • Limitation: System based logins are not supported on Linux. #709
  • Incredibly Detailed Logging: Various log levels exist now (Trace/Debug/Info/Warning/Error/Critical) and are sanely output to a rolling file on the host. Significant improvement over having to use the Windows event viewer with TGS3. Until such a point where bugs stop copping up I'd recommend Trace logging for the main log level.
  • Historical Deployment Data: Every time code is compiled the following data is logged and stored.
    • The User that initiated it.
    • When it was started.
    • When it finished.
    • All revision information including local/remote SHAs, test merged pull requests and their SHAs.
    • The BYOND version used.
    • The DMAPI version in the binary
  • Multiple chat bots per instance: Up to 65535 as a matter of fact (who knows why I chose that number?)!
  • Automatic Chat Bot Reconnection Intervals: Set in minutes.
  • Better Error State Handling: The Server and Watchdog aren't your momma's boys anymore. Every error state will be automatically resolved or reported with recommended actions.
  • Watchdog Heartbeats: An interval in seconds can now be set at which TGS will send /world/Topic() packets to DreamDaemon. If four of these are missed, the server will be rebooted. No more endless @key Holder pings in discord (and I can finally unmute the /tg/ guild)! This feature can be disabled.
  • Better DMAPI: No longer requires injecting a .NET runtime .dll into the DreamDaemon process. DD -> TGS communication is now handled securely via BYOND's native /world/Export() API ("But Cyberboss, BYOND only supports GET requests." Who said anything about respecting HTTP standards when dealing with BYOND?).
  • Safe/Ultrasafe Security Support: Thanks to the new DMAPI, the ultrasafe and safe security levels may be used without running into BYOND's limitations. But no one really cares...
  • Self Upgrading: To upgrade TGS3 you needed to download and run the installer. This was pretty seamless, but it's now even better in V4 as the command to upgrade can be given straight to the API. At that point the server will handle downloading the update, detaching running DreamDaemon instances, restarting with the new version, and reattaching to them. Easier than ever patch delivery.
  • Gasp TESTING: TGS4 currently has over 60% code coverage in automated unit and full stack integration tests. I aim to have that number ever increasing to prevent trivial mistakes. Big improvement over V3 which had... literally none...

Along with these features, nearly every single V3 feature has been included and possibly improved in some fashion. This includes stuff like Windows accounts for logins, and using ACLs for static file handling. The following exceptions exist but are planned for future updates:

  • Process memory/CPU diagnostic data is not generated: #611
  • Process dumps may not be created: #612
  • The DMAPI is required in DreamMaker code: #934
  • The option to "Initialize Game Directories" is no longer present, but a variant is still performed every deployment for smoother error handling.
  • Direct server announcements are no longer present but may be readded upon request.

Note that V3 instances cannot be imported into TGS4. This doesn't prevent the transfer of static game files however.

TGS4 is set to be the final major version. There will be no TGS5, not from me.
