The first stable tag containing the fix is `v2026.4.14`, and `openclaw@2026.4.14` includes the fix.\n\n## Fix Commit(s)\n\n- `024f4614a1a1831406e763adc40ef226e3d5e9ed`\n- `1dabfef28db523e7de81edeb3dd689e9171236a2`\n- `213c36cf51121ef6c05cfccd78037371f968f31a`\n- `7eecfa411df3d12e6b810e6ca5df47254fc3db3f`\n- PR: #66354, #66386\n\n## Release Process Note\n\nUsers should upgrade to `openclaw` 2026.4.14 or newer.
