Hi everyone,

We just released **Kong 1.0.3**. This is a patch release addressing several regressions introduced in some plugins, and improving the robustness of our migrations and core components.

📦 Download [Kong 1.0.3](https://bintray.com/kong) and follow the [recommended upgrade path](https://github.com/Kong/kong/blob/master/UPGRADE.md#upgrading-10x-patch-releases)!

**The main fixes included in this release are:**

- _request-transformer_: fix a regression causing the upstream Host header to be unconditionally set to that of the client request (effectively, as if the Route had `preserve_host` enabled).
- _cors_: fix a regression that prevented regex origins from being matched. Regexes such as `(.*[.])?example\.org` can now be used to match all sub-domains, while regexes containing `:` will be evaluated against the scheme and port of an origin (i.e. `^https?://(.*[.])?example\.org(:8000)?$` ).
- Ensure Routes that don’t have a `regex_priority` (e.g. if it was removed as part of a `PATCH` ) don’t prevent the router from being built.
- Improve Cassandra schema consensus logic when running migrations.

🗒 A complete list of fixes can be seen in the [1.0.3 Changelog](https://github.com/Kong/kong/blob/master/CHANGELOG.md#103) (no new features nor breaking changes).

🐋 The updated Docker image will be live shortly, as usual.

Kudos to [@jeremyjpj0916](https://github.com/jeremyjpj0916), [@mars](https://github.com/mars), and [@gchristidis](https://github.com/gchristidis) for promptly reporting these issues!

Happy Konging!
