   <h2>V1.81.0</h2>
   <p>In this release we drop support for Android API level 22 or lower 
(Lollipop or earlier), following Google Play Service’s <a 
href="https://developers.google.com/android/guides/setup";>discontinued updates 
for Lollipop (API levels 21 &amp; 22)</a> and now requires a minimum of API 
level 23 (Android 6.0 Marshmallow).</p>
   <p><strong>API Changes</strong></p>
   <ul>
   <li>api: Deprecate LoadBalancer.handleResolvedAddresses(). Developers 
maintaining custom LoadBalancer implementations should transition to using 
LoadBalancer.acceptResolvedAddresses(). Unlike the deprecated method, 
acceptResolvedAddresses() returns a Status object, allowing the load balancer 
to explicitly report success or reject the update if the provided addresses or 
configuration are invalid. (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/11623";>#11623</a>)</li>
   </ul>
   <p><strong>Behavior Changes</strong></p>
   <ul>
   <li>core: Enable dns &quot;caching&quot; on Android for 30 seconds to reduce 
CPU impact of a refresh loop with an LB policy (0675f70af). DnsNameResolver 
ignores re-resolution requests on OpenJDK-like platforms if it has been too 
soon since the last DNS query because InetAddress.getAllByName() has a cache 
with a fixed entry lifetime, but this logic was disabled for Android which does 
not have that style of cache. Android’s cache uses the result TTL, which will 
rarely be less than 30 seconds. This change would probably be most noticeable 
when 1) changing to a different network (e.g., from wifi to mobile), 2) the 
server has different addresses for different networks, and 3) the app is not 
using AndroidChannelBuilder with an <code>android.context.Context</code>. For 
reference, it seems Chrome caches for 1 minute</li>
   </ul>
   <p><strong>Bug Fixes</strong></p>
   <ul>
   <li>opentelemetry: Fix baggage propagation, the baggage propagation for 
opentelemetry introduced in <a 
href="https://redirect.github.com/grpc/grpc-java/pull/12389";>#12389</a> was 
broken. The context is decided once and used for all recording for the call, 
thus guaranteeing all record()s have consistent information.</li>
   <li>core: Address a race condition where 
<code>ManagedChannelOrphanWrapper</code> could incorrectly log a &quot;not 
shutdown properly&quot; warning during garbage collection when using 
directExecutor(). (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/12705";>#12705</a>) 
(d459338d9)</li>
   <li>xds: Fix xDS HTTP CONNECT's transport socket name bug which is now 
corrected to use <code>typeUrl</code>. (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/12740";>#12740</a>) 
(eac9fe961)</li>
   <li>xds: Fix an issue where subchannel metrics were dropping their 
association with the <code>backend_service</code>. This ensures xDS load 
balancing metrics are reported accurately. (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/12735";>#12735</a>)</li>
   </ul>
   <p><strong>New Features</strong></p>
   <ul>
   <li>netty: Add tcp metrics, by implementing a few of the metrics defined in 
<a href="https://redirect.github.com/grpc/proposal/pull/519";>A80</a>.</li>
   <li>api: Add a CallOption for a custom label on per-RPC metrics (0e39b2967). 
This CallOption is copied by grpc-opentelemetry to the 
<code>grpc.client.call.custom</code> label as defined by <a 
href="https://github.com/grpc/proposal/blob/master/A108-otel-custom-per-call-label.md";>gRFC
 A108</a>. See also the <a

Metrics guide</a> (update <a 
href="https://redirect.github.com/grpc/grpc.io/pull/1505";>in-progress</a>)</li>
   <li>xds: Add support for Weighted Round Robin (WRR) load balancing driven by 
custom backend metrics, implementing the behavior defined in gRFC A114. (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/12645";>#12645</a>)</li>
   <li>utils: Update <code>AdvancedTlsX509KeyManager</code> so that developers 
can now preserve and use key aliases when dynamically reloading TLS 
certificates. (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/12686";>#12686</a>)</li>
   </ul>
   <p><strong>Documentation</strong></p>
   <ul>
   <li>Update the &quot;Outgoing Flow Control&quot; section in the Manual Flow 
Control example to say onNext() does not block, but rather queues the messages 
in memory and advises developers to use CallStreamObserver.isReady() to prevent 
this memory exhaustion (<a

   Updates `io.grpc:grpc-context` from 1.80.0 to 1.81.0
   <details>
   <summary>Release notes</summary>
   <p><em>Sourced from <a 
href="https://github.com/grpc/grpc-java/releases";>io.grpc:grpc-context's 
releases</a>.</em></p>
   <blockquote>
   <h2>V1.81.0</h2>
   <p>In this release we drop support for Android API level 22 or lower 
(Lollipop or earlier), following Google Play Service’s <a 
href="https://developers.google.com/android/guides/setup";>discontinued updates 
for Lollipop (API levels 21 &amp; 22)</a> and now requires a minimum of API 
level 23 (Android 6.0 Marshmallow).</p>
   <p><strong>API Changes</strong></p>
   <ul>
   <li>api: Deprecate LoadBalancer.handleResolvedAddresses(). Developers 
maintaining custom LoadBalancer implementations should transition to using 
LoadBalancer.acceptResolvedAddresses(). Unlike the deprecated method, 
acceptResolvedAddresses() returns a Status object, allowing the load balancer 
to explicitly report success or reject the update if the provided addresses or 
configuration are invalid. (<a 
href="https://redirect.github.com/grpc/grpc-java/issues/11623";>#11623</a>)</li>
   </ul>
   <p><strong>Behavior Changes</strong></p>
   <ul>
   <li>core: Enable dns &quot;caching&quot; on Android for 30 seconds to reduce 
CPU impact of a refresh loop with an LB policy (0675f70af). DnsNameResolver 
ignores re-resolution requests on OpenJDK-like platforms if it has been too 
soon since the last DNS query because InetAddress.getAllByName() has a cache 
with a fixed entry lifetime, but this logic was disabled for Android which does 
not have that style of cache. Android’s cache uses the result TTL, which will 
rarely be less than 30 seconds. This change would probably be most noticeable 
when 1) changing to a different network (e.g., from wifi to mobile), 2) the 
server has different addresses for different networks, and 3) the app is not 
using AndroidChannelBuilder with an <code>android.context.Context</code>. For 
reference, it seems Chrome caches for 1 minute</li>
