# 1.0.3

## Upgrading

 * Caching and rate limiting rules now apply in this version, and it may be necessary to adjust the values
   for `RateLimitFilter.lock_timeout`, `RateLimitFilter.lock_bypage` and `RateLimitFilter.lock_byuserip` configs.
   See the [Developer Documentation](../developer.md) for information on how these affect cache performance and behaviour.
