Go 1.15 introduced changes to SSL/TLS connection validation which requires certificates to include a SAN. This field was not included in older certificates and clients relied on the CN field. You might see an error like x509: certificate relies on legacy Common Name field. We recommend that customers using Sourcegraph with an external database that is connected using SSL/TLS check whether the certificate is up to date. AWS RDS customers please reference AWS' documentation (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.SSL-certificate-rotation.html) on updating the SSL/TLS certificate for steps to rotate your certificate.

Structural search now supports searching unindexed revisions and indexed branches other than default.

Experimental: The webapp can now stream search results to the client, improving search performance. To enable it, add { "experimentalFeatures": { "searchStreaming": true } } in user settings.

New product research sign-up page added to user settings. Users can now opt in to participate in user research and provide feedback. Use the new site config option productResearchPage.enabled to disable access to the product research sign-up page.

Secrets (such as access tokens and passwords) will now appear as REDACTED when editing external service config, and in graphql API responses.

Improved performance of structural search on monorepo deployments.

When previewing a campaign spec, changesets can be filtered by current state or the action(s) to be performed.

Experimental: Sync Perforce depots directly through the Sourcegraph UI. To enable, use the feature flag "experimentalFeatures": { "perforce": "enabled" }. For more information on how to add your Perforce depots, please reference our docs (https://docs.sourcegraph.com/admin/repo/perforce).
