+- feat: support deno.json(c) files (#521)
+
+  As of 1.14 Deno supports an expanded set of configuration options in the
+  configuration file above the supported TypeScript `"compilerOptions"` options.
+
+  The extension supports validating these configuration files, as well as
+  recommends naming them `deno.json` or `deno.jsonc`.
+
+- fix: debug config provider (#513)
+- fix: better suppression of built in diagnostics (#514)
