STU 3 with optional new functionality and additional guidance. Since all of the new capabilities are optional for servers to support and for clients to use, valid Bulk Export STU 2 servers are also valid STU 3 servers and clients that work with STU 2 servers will also work with STU 3 servers.
Additional features defined in STU 3 includes include the ability to organize output resources in export files by a focal resource such as Patient instead of by resource type, the ability to return of partial export manifests during an export and after it is complete, an `_until` kickoff parameter, a capability statement extension for servers to indicate supported _typeFilter search parameters, and a Group profile and extension to support the creation of characteristic based cohorts using coarse-grained filters.
Clarifications to the `_typeFilter` parameter cover search expression support, boolean logic, and interactions with other filters. Additional guidance covers the use of capability urls and content encoding when providing and retrieving bulk files, and the use of FHIR Groups with Bulk Export.

01. An inline example is provided in the extension description
WARNING: StructureDefinition.where(url = 'http://hl7.org/fhir/uv/bulkdata/StructureDefinition/operation-not-supported'): The Implementation Guide contains no examples for this extension (1 uses)
02. This valueset is defined on the Expression type, not in this IG
A definition could not be found for Canonical URL 'http://www.rfc-editor.org/bcp/bcp13.txt' (1 uses)
03.This extension is defined in the Expression type, not in this IG
The extension http://hl7.org/fhir/StructureDefinition/elementdefinition-maxValueSet|5.3.0-ballot-tc1 is deprecated with the note Use additionalBinding extension or element instead (1 uses)
04. Group profile - this code system is used by the Group resource

05. The includeAssociatedData code system and valueset are specific to this IG and extremely unlikely to be used elsewhere. We will request TSMG approval.
Most code systems defined in HL7 IGs will need to move to THO later during the process. Consider giving this code system a THO URL now (See https://confluence.hl7.org/display/TSMG/Terminology+Play+Book, and/or talk to TSMG) (1 uses)
