## Validator Changes
* Fix for NPE rendering resources
* Consider CanonicalResource to be a CanonicalResource when validating profile references
* Work around error in R5 sdf-29 invariant
## Other code changes
* XHTML processing: Cater for "." in XML element and attribute names
* Handle R3 encoding of primitive values when validating profiles
* Improve error messaging when validating StructureDefinition
* Temporary Support for MedicationStatement in R5
* Work around for Identifier.use = ? in THO R5 package (old error)
* Rework Package API to allow for authentication on package servers
* Structure mapping now finds source Structure Definition by URI and sets ParserBase logical property appropriately.
* DOn't convert ig-r4 when converting package versions
***NO_CI***
## Validator Changes
* update FHIRPath implementation for corrections to 'as' (R5 only in validator)
* Critical Security fix: enforce correct paths when unpacking archives (SecurityAdvisory-1082, CVE TBA)
## Other code changes
* Update to latest FHIRPath for older versions
* Add new ElementModel based parser for StructureMaps
* go-publish related changes
* FTP Client upload and logging improvements
* Refactor base64 handling for Android compatibility
## Security Note
The validator unzips archive files to the local file system when
it is scanning zip files it has been asked to validate, and when it is
installing packages. These processes are now resistant to the zip-slip
vulnerability.
***NO_CI***
* Update cache and comparison downloads to use https
* Zip Slip tests and fix
* Zip Slip tests 2 and fix
* Add missing tempDir child in ScannerTest
* Add win format zip test
* Add tests to r4b
* Add tests and fixes for slips in tgz processing
* Update fhir-test-cases version
## Validator Changes
* Better tracking and reporting of snapshot generation issues
* Update FHIRPath implementation to R4 with all corrections and extensions from R5 implemnetation
## Other code changes
* Inclusion of SAXON dependency for processing XSLT
* Error message spacing correction
* Basic FTPClient implementation
* test NPE in markdown processing
* go-publish support
* Start implementing loading structure maps with validation
***NO_CI***
## Validator Changes
* Add support for fhir_comments in R2/R2B
* Add validator checking around versions in extension URLs
* Fix bug generating cross-version extensions
## Other code changes
* Fix minor NPEs running IG publisher
* Add new PE module (PEDefinition/PEInstance)
* Add support for liquid filters (resolve FHIRPath conflict)
* Fix up round-tripping of XPath constraints R4/R5
* Refactor R5 ProfileUtilities (and move rendering to rendering package)
* Fix appending text when generating snapshots
***NO_CI***
If the base text was null, appending a text in the derived element (using "...") would show a "null" before the text. This commit adds the method Utilities.appendDerivedTextToBase() to implement to correct behavior.
## Validator Changes
* Remove use of .fhir/package-client cache (only use the main .fhir/package now)
## Other code changes
* Hack work around for broken template input for R5 OperationOutcome
* Fix up problems with test case consistency in R5 test cases
* Add R5-snapshot3 version enum to R4 version list
***NO_CI***
## Validator Changes
* Change Java minimum version from 8 to 11
* Fix Error message missing parameter (very minor fix)
## Other code changes
