Technically: yes
From a “tagged versions” perspective, we’re figuring out a solution. You can absolutely use master and it’s always considered stable (with the condition that you also must be able to upgrade to the next version of master to ensure stability), but we are also exploring what some more reasonable low-cost process would be to continue to tag versions.
“Sentry 10” is coming soon, whether we call it that or not, but open source users probably won’t be as excited as it’ll require running our new Snuba service (which is an API layer on top of Clickhouse). We’ll talk more about this in the future, but the tl;dr is its going to unfortunately be a lot harder to run yourselves because of the nature of the datastore changes.
