It is an incremental update to Bazel 3.4.</p> <h2>Incompatible changes</h2> <ul> <li>Remove the <code>--experimental_process_wrapper_wait_fix</code> flag.</li> <li>Remove the <code>--experimental_ui_deduplicate</code> flag.</li> <li>Remove the <code>--experimental_transparent_compression</code> flag.</li> <li>Remove the <code>--experimental_action_args</code> flag.</li> <li>Remove the <code>--incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfiles_tree</code> flag.</li> <li>Bazel now correctly prefers Xcode versions in <code>/Applications</code> over other paths, by default. This resolves an issue with accidentally picking up an Xcode version from a Time Machine backup or network disk. If you rely on the old behavior, move your desired Xcode version to <code>/Applications</code>.</li> </ul> <h2>Rules</h2> <h3>C++</h3> <ul> <li>Add <a href="https://docs.bazel.build/versions/3.5.0/skylark/lib/cc_common.html#compile"><code>cc_common.compile</code></a> support for <code>include_prefix</code> / <code>strip_include_prefix</code>.</li> </ul> <h3>Android</h3> <ul> <li>Support signing key rotation in <code>android_binary</code>.</li> </ul> <h3>Apple</h3> <ul> <li><a href="https://docs.bazel.build/versions/3.5.0/command-line-reference.html#flag--apple_bitcode"><code>--apple_bitcode</code></a> now takes an optional platform and only applies the Bitcode mode to that platform if present. The option may be provided multiple times.</li> <li>Add optional <code>oso_prefix_is_pwd</code> feature for Apple builds.</li> <li><code>NS_BLOCK_ASSERTIONS</code> is now passed for all Apple architectures.</li> </ul> <h3>Java</h3> <ul> <li>Java 14 is now supported through custom <code>toolchain_jdk_14</code>. The <code>java_tools</code> repository provides this support in the <a href="https://github.com/bazelbuild/java_tools/releases/tag/javac14_v1.0">java_tools with javac14 v1.0</a> release.</li> </ul> <h2>Other changes</h2> <ul> <li><code>cquery</code> now follows aspects when the <a href="https://docs.bazel.build/versions/3.5.0/cquery.html#cquery-options"><code>--include_aspects</code></a> flag is used.</li> <li>Add support to <code>bazel/crosstool</code> for building arm64 on macos.</li> <li>Update coverage configuration for Python, <code>filegroup</code>, and shell script rules to distinguish between source and dependency attributes.</li> <li>Add <a href="https://docs.bazel.build/versions/3.5.0/skylark/lib/InstrumentedFilesInfo.html"><code>InstrumentedFilesInfo</code></a> provider to Starlark globals.</li> <li>Make <code>filegroup</code> always forward <code>InstrumentedFilesProvider</code> and not collect any sources directly.</li> <li>Update Starlark error reporting and the call stack. This may cause changes in the locations where errors were previously reported.</li> <li>Allow dot ('.') in <code>workspace</code> names.
