Unexpected major release because commit description includes a line starting with "Breaking change"

[brian-smith-tcril]

It's possible there isn't a reasonable way to avoid this, but I recently encountered an issue where a commit message triggered a unexpected major release for me.

diff --git a/test/integration.test.js b/test/integration.test.js
index 112bc3a..550f9ee 100644

   t.true(t.context.log.calledWith("Analysis of %s commits complete: %s release", 2, "minor"));
 });

+
+      Breaking change for unsupported use case but not a breaking API change
+

+    },
+  ];
+  const releaseType = await analyzeCommits({}, { cwd, commits, logger: t.context.logger });
+
+  t.is(releaseType, "minor");
+});
+
 test('Accept "preset" option', async (t) => {
   const commits = [
     { hash: "123", message: "Fix: First fix (fixes #123)" },

There may not be a reasonable way to prevent this without breaking intended use, but when combined with https://github.com/semantic-release/semantic-release/issues/3721 this led to quite the predicament.

semantic-release uses https://www.npmjs.com/package/conventional-changelog-angular internally as the default preset. what you describe is likely not specific to semantic-release, but that preset. you might consider confirming if you can confirm the same behavior with it directly and opening an issue against that package, which is not maintained by this team
