Thrift is specifically designed to support non-atomic version changes
across client and server code. This allows you to upgrade your
-server while still being able service older clients; or have newer
+server while still being able to service older clients; or have newer
clients issue requests to older servers. An excellent community-provided
write-up about thrift and compatibility when versioning an API can be
found in the [Thrift Missing Guide](https://diwakergupta.github.io/thrift-missing-guide/#_versioning_compatibility).
