This is the preliminary status list tracking the progress of Library Working Group proposals following publication of the C++11 standard. Its form is likely to evolve rapidly over the next few mailings, until we find the form that best serves the Libray Working Group's needs.
The Library Working Group is not immediately embarking on any TSs, and expect the next revision of the standard to be delivered around 2017. As such, we are open to submissions for both extensions of existing library facilities, and entirely new facilities. Only once technical work is complete will we target a new Technical Specificationm, or apply straight to the current working paper.
As projects emerge, Study Groups may be formed to shepherd the proposals into some final deliverable form, such as producing a candidate TS document. This stats list aims to track the progress of proposals through those studay groups as well. Initially, there will be two LWG study groups, for filesystem and networking proposals, and a cross-functional study group for concurrency related proposals, that will naturally overlap with Core and Evolution activity.

| Active Proposals | ||
| These papers present libraries that have been favorably reviewed at recent meetings, but are not yet ready to be adopted in some larger work unit. Further revisions of these papers are expected. | ||

| New Library Components Previosuly Considered for a Future TR | ||
| These papers present libraries that were actively under consideration for a future TR, when work on TR2 was deferred pending. These papers were viewed positively at the time, but were due at least one more revision before any adoption, and most will need some reworking to reflect the addition of C++11 language facilities. | ||
