 Name:                keter
-Version:             1.2.1
+Version:             1.3.0
 Synopsis:            Web application deployment manager, focusing on Haskell web frameworks
 Description:
     Handles deployment of web apps, providing a reverse proxy to achieve zero downtime deployments. For more information, please see the README on Github: <https://github.com/snoyberg/keter#readme>
     .
     Release history:
     .
+    [1.3.0] Upgrade to conduit 1.1
+    .
     [1.0.1] Permit use of wildcard subdomains and exceptions to wildcards. Convert internal strings to use Data.Text in more places. (Although internationalized domain names are not supported unless entered in punycode in configuration files.)
     .
     [1.0.0] Significant overhaul. We now support monitoring of much more arbitrary jobs (e.g., background tasks), have a proper plugin system (PostgreSQL is no longer a required component), and have a much better system for tracking hostname mapping changes.
