Sourcegraph 5.8

• Reduce peak memory required for Zoekt indexing
• Improve search ranking by using repo freshness as a scoring signal

With this change we rank repository search results by similarity. Before, repository search results were ordered by star count instead. This affects suggestions and repository search results. To disable this feature and return to the previous behavior, set { "experimentalFeatures": { "disableOrderBySimilarity": true}} in global settings.

The GraphQL endpoint search.results.repositories now returns the list of repositories in the order of the matches we found. Before, repositories were sorted by id.

We have updated the client-side query validation to allow combining rev: filters with query-based search contexts.

For very large repositories, search jobs could time out while fetching the repository. Now, search jobs can fetch and search over repositories, even if they take a long time to fetch.

We added a new database index to speed up a janitor job which is run as part of Search Jobs. Before, the janitor job might have significantly delayed migrations during an upgrade.

The new usagesForSymbol API correctly searches repos whose names contain spaces or other special characters.

Go cross-repo navigation for tagged versions should work better when using scip-go for auto-indexing. Navigation based on SCIP indexes generated using scip-go in CI or cron jobs should be unaffected.
