 * **Why is it taking so long?** - I spent the last several months trying to make TinyTDS/FreeTDS strong vs working on the adapter. If you did not know, the FreeTDS finally hit a v1.0 release which has been in the works for several years. It is a major achievement by that team. I thought it was more important to get the low level connection strong before doing the adapter work. We will get there soon.
 * **What branch you working on?** - Right now I am on the [rails5](https://github.com/rails-sqlserver/activerecord-sqlserver-adapter/tree/rails5) branch.
