== Breaking changes
**Breaking changes in 2.2**
Although 2.2 is fully compatible with configurations from older versions, there are some architectural
changes to the pipeline that users need to take into consideration before deploying in production.
These changes are not strictly "breaking" in the semantic versioning sense, but they make Logstash behave differently
in runtime, and can also affect performance. We have compiled such a list in the <<_upgrading_logstash_to_2.2>> section.
Please review it before deploying 2.2 version.
**Changes in 2.0**
Version 2.0 of Logstash has some changes that are incompatible with previous versions of Logstash. This section discusses
what you need to be aware of when migrating to this version.
