 ### Fixed
 
-- Fixed performance problems with unserializing jobs. This greatly **increased performance** by avoiding redundant calls to Redis storage. Should help a lot with huge workflows spawning thousands of jobs. Previously each job loaded whole workflow instance when executed.
+- Fix graph rendering with `gush viz` command. Sometimes it rendered the last job detached from others, because it was using a class name instead of job name as ID.

 ### Changed
 
 - **BREAKING CHANGE** `Gushfile.rb` is now renamed to `Gushfile`
 - **BREAKING CHANGE** Internal code for reporting status via Redis pub/sub has been removed, since it wasn't used for a long time.
--  **BREAKING CHANGE** - jobs are expected to have a `perform` method instead of `work` like in < 1.0.0 versions.
--  **BREAKING CHANGE** - `payloads` method available inside jobs is now an array of hashes, instead of a hash, this allows for a more flexible approach to reusing a single job in many situations. Previously payloads were grouped by predecessor's class name, so you were forced to hardcode that class name in its descendants' code.
