+## Poison Java gencode
+
+We are patching a change into the 25.x branch that will poison Java gencode that
+was created prior to the
+[3.21.7 release](https://github.com/protocolbuffers/protobuf/releases/tag/v21.7).
+We will then mark all versions of Java protobuf from 3.21.7 through 3.25.5 as
+vulnerable to the
+[footmitten CVE](https://github.com/protocolbuffers/protobuf/security/advisories/GHSA-h4h5-3hr4-j3g2).
+
+After this change is patched in, protobuf will throw an
+`UnsupportedOperationException` from the
+[`makeExtensionsImmutable`](https://protobuf.dev/reference/java/api-docs/com/google/protobuf/GeneratedMessage.html#makeExtensionsImmutable\(\))
+method unless you set the system property
+"`-Dcom.google.protobuf.use_unsafe_pre22_gencode`". Using this system property
+can buy you some time if you can't update your code immediately, but should be
+considered a short-term workaround.
+
+## Poison MSVC + Bazel
+
+We will be dropping support for using Bazel and MSVC together in v34. As of v30,
+we will poison this combination with an error unless you specify the opt-out
+flag `--define=protobuf_allow_msvc=true` to silence it.
+
+MSVC's path length limits combined with Bazel's sandboxing have become
+increasingly difficult to support in combination. Rather than randomly break
+users who install protobuf into a long path, we will prohibit the use of MSVC
+from Bazel altogether. We will continue to support MSVC with CMake, and begin
+supporting [clang-cl](https://clang.llvm.org/docs/UsersManual.html#clang-cl)
+with Bazel. For any feedback or discussion, see
