+[Bazel 3.7](https://github.com/bazelbuild/bazel/releases/tag/3.7.0) is a [minor
+release](https://docs.bazel.build/versions/3.7.0/backward-compatibility.html).
+It is an incremental update to Bazel 3.6.
+
+## Incompatible changes
+
+*   The syntax `//foo/BUILD` can no longer be used on the command line to refer to the `//foo:BUILD` target. Use `//foo:BUILD` (preferred) or `foo/BUILD` instead. This does not affect BUILD/bzl files, where that syntax already didn't work.
+*   Remove the `--objc_header_scanner_tool` flag. The flag was primarily used internally, and to our knowledge, a compatible tool was never released. Therefore this flag is believed to be unused.
+
+## Android
+
+*   Non-android targets are not in error when `android_sdk_repository` is present but invalid.
+
+## Java
+
+*   Include `resources` attribute in dependency attributes for `java_*` coverage configuration.
+*   Javac now supports [multiplex workers](https://docs.bazel.build/versions/3.7.0/multiplex-worker.html), but it is not enabled in the toolchain.
+
+## Other changes
+
+*   `select()` directly [supports](https://docs.bazel.build/versions/3.7.0/configurable-attributes.html#platforms) `constraint_value` with no need for an intermediate `config_setting`.
+*   [`--trim\_test\_configuration`](https://docs.bazel.build/versions/3.7.0/command-line-reference.html#flag--trim_test_configuration) should work for almost all cases when a non-test target depends on a test.
+*   Bazel now allows symbolic links that point to their own ancestor unless they are traversed recursively by e.g. a `//...` recursive target pattern or a recursive glob.
+*   Generated Go protobufs no longer depend on `//net/proto2/go:proto`
