#### Internal API changes

The `okhttp3.internal` package is not a published API and we change it frequently without warning.
Depending on code in this package is bad and will cause you problems with any upgrade! But the 4.x
will be particularly painful to naughty developers that import from this package! We changed a lot
to take advantage of sweet Kotlin features.

#### Credentials.basic()

 * Fix 1.5.0 regression where connections should not have been recycled.
 * Fix 1.5.0 regression where transparent Gzip was broken by attempting to
   recover from another I/O failure.
 * Fix problems where spdy/3.1 headers may not have been compressed properly.
 * Fix problems with spdy/3.1 and http/2 where the wrong window size was being
   used.
 * Fix 1.5.0 regression where conditional cache responses could corrupt the
   connection pool.

        // I'm fully aware that the file could just be moved using File.rename but
        // there are bugs in various JVM that have problems doing this across
        // different filesystem. So we'll incur the small hit to actually copy
        // here and be safe. jvz.

        List<? extends ValueSource> valueSources = createValueSources(model, projectDir, config, problems);
        List<? extends InterpolationPostProcessor> postProcessors = createPostProcessors(model, projectDir, config);

        InnerInterpolator innerInterpolator = createInterpolator(valueSources, postProcessors, problems);

Ainsi, vous pouvez déclarer votre fonction comme suit :

{* ../../docs_src/path_params_numeric_validations/tutorial002.py hl[7] *}

Mais gardez à l'esprit que si vous utilisez `Annotated`, vous n'aurez pas ce problème, cela n'aura pas d'importance car vous n'utilisez pas les valeurs par défaut des paramètres de fonction pour `Query()` ou `Path()`.

{* ../../docs_src/path_params_numeric_validations/tutorial002_an_py39.py hl[10] *}

Então, você pode declarar sua função assim:

{* ../../docs_src/path_params_numeric_validations/tutorial002_py39.py hl[7] *}

Mas tenha em mente que, se você usar `Annotated`, você não terá esse problema, não fará diferença, pois você não está usando valores padrão de parâmetros de função para `Query()` ou `Path()`.

{* ../../docs_src/path_params_numeric_validations/tutorial002_an_py39.py *}

        // win98 observed not returning nativeFileSystem

Cuanto más simple sea el problema resuelto por la herramienta, mejor rendimiento tendrá. Y la mayoría de los benchmarks no prueban las funcionalidades adicionales proporcionadas por la herramienta.
