 # Design
+
 - Gepsio now supports the direct loading of schemas and linkbase documents hosted on `sec.gov`. Previous versions of Gepsio supported the loading of XBRL document instances hosted on `sec.gov`, but did not support the loading of any ancillary documents also hosted on `sec.gov`.
 
 # Bug Fixes
 
 - Fixed a bug which caused XBRL document instances hosted on `sec.gov` to report schema load errors and report that no facts are available in the instance. See the Design note for more information. This fixes [Issue 56](https://github.com/JeffFerguson/gepsio/issues/56).
 - Fixed a bug which caused calls to `GetHashCode()` on schema `Element` objects without explicitly defined `ID` attributes to throw a `NullReferenceException`. This fixes [Issue 57](https://github.com/JeffFerguson/gepsio/issues/57).
