   Please make sure you are reading and/or consuming the official SV Operations Calendar, which is posted here:

   You can use this on the web, and you can use this as a Google Calendar via the "Subscribe" link on this webpage. 
   
   You may also consume this calendar as JSON, here:

   You MUST UPGRADE to the recommended versions before the dates where this calendar says a specific version is required. If you do not upgrade, you will lose the ability to transact with your node, and in some cases you will lose the ability to access your node. DO NOT DELAY YOUR UPGRADES. 
   
   Specific versions will be required to prepare for breaking configuration changes, including Daml Model adoption, and also for Logical Synchronizer Upgrades. Each event that requires a specified version is in the calendar, planned on a specific week of each month, several months in advance. There will be some cases when the Splice team recommends cancelling a given event because the breaking change is not ready, or the Super Validators may decide to not adopt a given breaking change. In those cases the event will be marked as "cancelled". 
   
   Make sure you are reading, consuming and tracking this calendar.
