 7. **Review of Old Untriaged Issues:** Time permitting, each meeting will look at all [untriaged issues older than 14 days](https://github.com/opensearch-project/OpenSearch/issues?q=is%3Aissue+is%3Aopen+label%3Auntriaged+created%3A%3C2024-05-20) to prevent issues from falling through the cracks (note the GitHub API does not allow for relative times, so the date in this search must be updated every meeting).
