No new releases nor deployments happen in the month of December.\n\nAt times, small update patches will be released for fixes that should not wait for the next release. These are nearly always fixes for critical product or security issues. Ideally, no new features would ever be included in a patch release. The application of patch updates follows the same process as upgrading during a standard release.\n\n### Release numbers\n\nThe release numbering scheme for Looker (Google Cloud core) uses the same release numbering as for Looker (original) instances, which is a three-number sequence: X.Y.Z, where X is the last two digits of the year of the release, Y is the monthly version (starting with 0 in January, and using even numbers for each subsequent month), and Z is the patch release version. For example, Looker (Google Cloud core) 23.10.1 would be the first patch of the Looker (Google Cloud core) release from June of 2023.\n\n### Release notes\n\nStay current with any new features and issue fixes by checking out the release notes. See the [Looker releases](/looker/docs/release-notes) page for links to the release notes and changelog for the latest release.\n\nUpdate process\n--------------\n\nLooker (Google Cloud core) applies updates on a rolling basis over the course of a couple of weeks. If you have [defined a preferred window for maintenance](/looker/docs/looker-core-maintenance#set_a_preferred_window_for_maintenance) of your Looker (Google Cloud core) instance, the Looker (Google Cloud core) Release and Ops teams will apply updates during the maintenance window. If you have not set a maintenance window, you will receive the update within two weeks of the version rollout.\n\nIf you have [set a maintenance window](/looker/docs/looker-core-maintenance#set_a_preferred_window_for_maintenance) for your Looker (Google Cloud core) instance, you can [opt in to receive notifications](/looker/docs/looker-core-maintenance#opt_in_to_maintenance_notifications) ahead of upcoming maintenance. Updates generally take around an hour within the maintenance window and may result in downtime.\n| **Important:** Security upgrades may be applied outside of a preferred maintenance window or during a deny maintenance period. Such upgrades may take place without notifications.\n\n### What if I need to skip a new release version?\n\nYou can defer scheduled maintenance of your Looker (Google Cloud core) instance by defining a [deny maintenance period](/looker/docs/looker-core-maintenance#configure_a_deny_maintenance_period) of up to 60 days in length.\n| **Note:** You must allow at least 14 days of maintenance availability between any 2 deny maintenance periods.\n\n### Does maintenance downtime count toward the SLA?\n\nDowntime associated with maintenance does not apply towards the Looker (Google Cloud core) Service Level Agreement.\n\n### Update your Looker (Google Cloud core) version following a deny maintenance period\n\nFollowing a deny maintenance period, your Looker (Google Cloud core) instance will usually be updated during the first release that occurs after your deny maintenance period ends.\n\nExtended support release program\n--------------------------------\n\nLooker (Google Cloud core) does not provide an [extended support release (ESR)](/looker/docs/standard-extended-support-release-program-overview) program.\n\nGetting support\n---------------\n\nIf you have questions, see the [Getting support for Looker (Google Cloud core)](/looker/docs/looker-core-support) page for information on troubleshooting and contacting Google Cloud support."]]
