## Version 5.0.0-alpha.17

_2025-06-29_

This release stabilizes many APIs for the imminent OkHttp 5.0.0 release.

 *  New: `TrailersSource`, a public API for HTTP trailers. Production callers shouldn't need this
    as the API to read response trailers is unchanged. Testers may use this new stable API to
    supply trailers for a `Response`.

    val builtRequestWithoutCache = requestWithoutCache.newBuilder().url("http://localhost/api/foo").build()
    assertThat(builtRequestWithoutCache.url).isEqualTo(
      "http://localhost/api/foo".toHttpUrl(),
    )
    val requestWithCache =
      Request
        .Builder()
        .url("http://localhost/api")
        .build()
    // cache url object

  fun uninitializedURI() {
    val request = Request.Builder().url("http://localhost/api").build()
    assertThat(request.url.toUri()).isEqualTo(URI("http://localhost/api"))
    assertThat(request.url).isEqualTo("http://localhost/api".toHttpUrl())
  }

  @Test
  fun newBuilderUrlResetsUrl() {
    val requestWithoutCache = Request.Builder().url("http://localhost/api").build()

    introduction to this new API.

 *  New: APIs to iterate and selectively clear the response cache.
 *  New: Support for SOCKS proxies.
 *  New: Support for `TLS_FALLBACK_SCSV`.
 *  New: Update HTTP/2 support to `h2-16` and `hpack-10`.
 *  New: APIs to prevent retrying non-idempotent requests.
 *  Fix: Drop NPN support. Going forward we support ALPN only.

Code Cleanup
------------

IntelliJ and Android Studio offer a **Code Cleanup** feature that will automatically update
deprecated APIs with their replacements. Access this feature from the _Search Anywhere_ dialog
(double-press shift) or under the _Analyze_ menu.

We’ve included deprecated APIs in OkHttp 4.0 because they make migration easy. We will remove them
