## Über Versionen

Gemäß den Konventionen zur semantischen Versionierung könnte jede Version unter `1.0.0` potenziell nicht abwärtskompatible Änderungen hinzufügen.

FastAPI folgt auch der Konvention, dass jede „PATCH“-Versionsänderung für Bugfixes und abwärtskompatible Änderungen gedacht ist.

/// tip | Tipp

Der „PATCH“ ist die letzte Zahl, zum Beispiel ist in `0.2.3` die PATCH-Version `3`.

DIR:
  DIR points to a directory on a filesystem. When you want to combine
  multiple drives into a single large system, pass one directory per
  filesystem separated by space. You may also use a '...' convention
  to abbreviate the directory arguments. Remote directories in a
  distributed setup are encoded as HTTP(s) URIs.
```

## Common usage

Standalone erasure coded configuration with 4 sets with 16 drives each.

Go 1.22 added contention on runtime-internal locks to the [`mutex`
profile](/pkg/runtime/pprof#Profile). Contention on these locks is always
reported at `runtime._LostContendedRuntimeLock`. Complete stack traces of
runtime locks can be enabled with the [`runtimecontentionstacks`

A single HTTP call may require follow-up requests to be made to handle authentication challenges, redirects, and HTTP-layer timeouts. In such cases multiple connections, requests, and responses may be attempted. Follow-ups are another reason a single call may trigger multiple events of the same type.
