#### Usando `StreamingResponse` con objetos similares a archivos

Si tienes un objeto similar a un archivo (por ejemplo, el objeto devuelto por `open()`), puedes crear una función generadora para iterar sobre ese objeto similar a un archivo.

De esa manera, no tienes que leerlo todo primero en memoria, y puedes pasar esa función generadora al `StreamingResponse`, y devolverlo.

    suite.addTest(
        ConcurrentMapTestSuiteBuilder.using(
                new TestStringCacheGenerator(createCacheBuilder().weakKeys()))
            .named("LocalCache with weakKeys") // keys are string literals and won't be GC'd
            .withFeatures(
                CollectionSize.ANY,
                MapFeature.GENERAL_PURPOSE,
                CollectionFeature.SUPPORTS_ITERATOR_REMOVE)
            .createTestSuite());

### API Change

- Kube-apiserver: Fixes handling of CRD schemas containing literal null values in enums (#104990, @liggitt) [SIG API Machinery, Apps and Network]

### Bug or Regression

     *
     * This method replaces all occurrences of '*' with '\*' and
     * all occurrences of '?' with '\?' to ensure that these characters
     * are treated as literals rather than wildcard characters in queries.
     *
     * @param query the query string to escape
     * @return the escaped query string
     */
    public static String escapeWildcardQuery(final String query) {

- Openapi-controller: remove the trailing `1` character literal from the rate limiting metric `APIServiceOpenAPIAggregationControllerQueue1` and rename it to `open_api_aggregation_controller` to adhere to Prometheus best practices.

 *  Fix: Update the stored timestamp on conditional cache hits.
 *  New: Optimized HTTP/2 request header encoding. More headers are HPACK-encoded and string
    literals are now Huffman-encoded.
 *  New: Expose `Part` headers and body in `Multipart`.
 *  New: Make `ResponseBody.string()` and `ResponseBody.charStream()` BOM-aware. If your HTTP

  `Only mustard isn't a bird,' Alice remarked.

  `Right, as usual,' said the Duchess:  `what a clear way you
have of putting things!'

  `It's a mineral, I THINK,' said Alice.

  `Of course it is,' said the Duchess, who seemed ready to agree
to everything that Alice said; `there's a large mustard-mine near
here.  And the moral of that is--"The more there is of mine, the
