Following the Semantic Versioning conventions, any version below `1.0.0` could potentially add breaking changes.

FastAPI also follows the convention that any "PATCH" version change is for bug fixes and non-breaking changes.

/// tip

The "PATCH" is the last number, for example, in `0.2.3`, the PATCH version is `3`.

///

So, you should be able to pin to a version like:

```txt
fastapi>=0.45.0,<0.46.0
```

     *
     * @param paths the path to format as a string
     * @return the option associated to this path type followed by the given path elements,
     *         or an empty array if there is no path element.
     */
    @Nonnull
    String[] option(Iterable<? extends Path> paths);

    /**
     * Returns the name of this path type. For example, if this path type

    // not needed when compiling with recent JDKs, e.g. 17
    options.compilerArgs.add("-Xlint:-requires-transitive-automatic")

    // Patch the compileKotlinJvm output classes into the compilation so exporting packages works correctly.
    options.compilerArgs.addAll(
      listOf(
        "--patch-module",
        "$moduleName=${compileKotlinTask.destinationDirectory.get().asFile}",
      ),
    )

          Conscrypt.isAvailable() && atLeastVersion(2, 1, 0) -> true

          else -> false
        }
      } catch (e: NoClassDefFoundError) {
        false
      } catch (e: ClassNotFoundException) {
        false
      }

    fun atLeastVersion(
      major: Int,
      minor: Int = 0,
      patch: Int = 0,
    ): Boolean {
      val conscryptVersion = Conscrypt.version() ?: return false

你可以在[发行说明](../release-notes.md)中查看可用版本（例如查看当前最新版本）。

## 关于版本 { #about-versions }

遵循语义版本控制约定，任何低于`1.0.0`的版本都可能会添加 breaking changes。

FastAPI 还遵循这样的约定：任何"PATCH"版本更改都是为了bug修复和non-breaking changes。

/// tip | 提示

"PATCH"是最后一个数字，例如，在`0.2.3`中，PATCH版本是`3`。

///

因此，你应该能够固定到如下版本：

```txt
fastapi>=0.45.0,<0.46.0
```

"MINOR"版本中会添加breaking changes和新功能。
