## 1.5.0

### Updates (R4)

* Added a `ResourceList` type for codes which are part of the [ResourceTypes](https://hl7.org/fhir/codesystem-resource-types.html) codesystem
* Updated `Required` status for: MessageDefinition.focus.code, CapabilityStatement.rest.resource.type, GraphDefinition.start, GraphDefinition.link.target.type, ImplementationGuide.global.type, SearchParameter.base, SearchParameter.target, OperationDefinition.resource, CompartmentDefinition.resource.code, ExampleScenario.instance.resourceType
* Changed `BundleEntry.resource` and other uses of generic `Resource` to a union type which supports inference and narrowing.
* Correct type for `ParametersParameter.resource`

## 1.4.9

### Updates (R3)

* Made a generic `Resource` type which is a union of all other resources to allow type narrowing when working with Bundles and Contained Resources. For example:
```
const res = bundle.entry[0].resource
// res -> fhirR3.Resource
if(res.resourceType === 'Organization'){
  // TypeScript will infer the type of Organization automatically
  // res -> fhirR3.Organization
```

## 1.4.8

### Updates (R4)

* Made `resourceType` a `required` for Resource for R4.

## 1.4.7

### Updates (R3)

* Fixed property `asserted` to `asserter` for AllergyIntolerance resource. 
## 1.4.6

### Updates (R3)

## 1.4.3

### Updates (R4)

* Updated `_short` property to `short` used in `elementDefinition.ts` for R4.
* Updated `_abstract` property to `abstract` used in `structureDefinition.ts, valueSetContains.ts and IStructureDefinition.ts` for R4.

## 1.4.2

### Updates (R3)

* Removed `Id` type used by `Meta.versionId` and changed to `string`.

## 1.4.1

### Updates (R3)

## 1.4.0
---
### Updates (R3)

* The `Participant` class has been re-tooled to only be used in the `Appointment` class
* Droped the `Period` field in the `Participant` class as it is not used in `Appointment.participant`
* Added `EncounterParticipant` to replace the class type in `Encounter.participant`
  * `EncounterParticipant` follows the STU3 spec for `Encounter.participant` 

This release introduces a breaking change for Encounter.If you're using `Encounter` in your code, the `participant` field will have a new type, `EncounterParticipant` with the appropriate changes. This will break existing implementations, unless they are updated to take advantage of the new `EncounterParticipant` class.  The `Period` in the `Participant` class has been removed as it's not using by the `Appointment.participant` field.
