     - Class-bound attributes sent as arguments to 
       relation()'s remote_side and foreign_keys parameters 
       are now accepted, allowing them to be used with declarative.
+      Additionally fixed bugs involving order_by being
+      specified as a class-bound attribute in conjunction
+      with eager loading.
 - mysql
     - Quoting of MSEnum values for use in CREATE TABLE is now

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
