+- update to version 2.5.5:
+ - Enhancements:
+  - Support for new RiskIQ Illuminate Vulnerability Intelligence API endpoints in core API library.
+  - New `cves` property of AttackSurface objects finds vulnerabilities impacting assets within that
+    attack surface. Works identically for the primary (your own) attack surface and third-party
+    attack surfaces.
+  - New `AttackSurfaceCVEs` record list to contain a list of `AttackSurfaceCVE` objects, with properties
+    to access the vulnerability report, RiskIQ priority score, and list of impacted assets.
+  - New `VulnArticle` object to provide details on a CVE and discover the list of third-party vendors
+    with assets impacted by the vuln. Custom views in the article's `to_dataframe()` method render
+    dataframes focused on article references, component detections, and third-party impacts.
+  - New helper method `analyzer.AttackSurface()` to directly load an attack surface. Works without params to load
+    the main attack surface, with an ID to load a third-party vendor attack surface by ID, or with a string
+    to find an attack surface by vendor name. 
+  - Re-organized Illuminate-specific code in the `analyzer` module into distinct files located under a
+    subpackage. Existing imports in client code should not be impacted. 
+ - Pull Requests:
+  - Publishes pull request #38 "Remove ez_setup dependancy."
