+This document captures both near term steps (aka Roadmap) and feature requests.
 The goal is to add some visibility and guidance for future additions and Pull Requests, as well as to keep the Issues list clear of enhancement requests so that bugs are more visible.
 
 ## Roadmap
 
 _Lists agreed upon next steps in approximate priority order._
 
- * ~~publish to the CocoaPods directory at https://cocoapods.org/, per [#257](https://github.com/stephencelis/SQLite.swift/issues/257)~~ _jan 7, 2016_)
- * add SQLCipher back into the product as a separate repo, per [#311](https://github.com/stephencelis/SQLite.swift/issues/311), _in progress jan 6, 2016_
-
-
 ## Feature Requests
 
 _A gathering point for ideas for new features. In general, the corresponding issue will be closed once it is added here, with the assumption that it will be referred to when it comes time to add the corresponding feature._
 
 ### Packaging
 
- * add TV OS support, per [#272](https://github.com/stephencelis/SQLite.swift/issues/272) - currently pending SQLiteCipher merge and/or adding ability for user to pick their preferred [SQLCipher](https://github.com/sqlcipher/sqlcipher) branch
- * linux support via Swift Package Manager, per [#315](https://github.com/stephencelis/SQLite.swift/issues/315)
