 # Change Log
 
+##[v1.5.0](https://github.com/Polymer/polymer/tree/v1.5.0) (2016-05-31)
+- Fix test in Firefox that was hacked to work in Canary (instead filed https://bugs.chromium.org/p/chromium/issues/detail?id=614198). ([commit](https://github.com/Polymer/polymer/commit/1e2aed5))
+
+- remove unneeded argument ([commit](https://github.com/Polymer/polymer/commit/4a99b83))

+- slight optimization, avoid work if no cssText is set. ([commit](https://github.com/Polymer/polymer/commit/ce0bf86))

+- More efficient fix for #3661. Re-uses cached style element that needs to be replaced in the document rather than creating a new one. ([commit](https://github.com/Polymer/polymer/commit/63f91ae))
+
+- Fixes #3661: ensure that cached style points to the applied style for Shady DOM styling. This ensures that the cache can be used to determine if a style needs to be applied to the document and prevents extra unnecessary styles from being added.
