## 2025-04-03 - 4.1.3 - fix(core)
Refactor module imports to use the centralized plugins module and update relative paths across the codebase. Also remove the obsolete test file (test/test.other-formats-corpus.ts) and update file metadata in test outputs.

- Updated import statements in modules (e.g., ts/classes.xinvoice.ts, ts/formats/*, and ts/interfaces/common.ts) to import DOMParser, xpath, and other dependencies from './plugins.js' instead of directly from 'xmldom' and 'xpath'.
- Adjusted import paths in test asset files such as test/assets/letter/letter1.ts.
- Removed the obsolete test file test/test.other-formats-corpus.ts.

- Clarified supported invoice standards and provided a concise summary of format details

## 2025-04-03 - 4.1.1 - fix(zugferd)
Refactor Zugferd decoders to properly extract house numbers from street names and remove unused imports; update readme hints with additional TInvoice reference and refresh PDF metadata timestamps.

- Use regex in zugferd.decoder.ts and zugferd.v1.decoder.ts to split the street name and extract the house number.
- Remove the unnecessary 'general' import from '@tsclass/tsclass' in zugferd decoder files.
- Update readme.hints.md with a reference to the TInvoice type from @tsclass/tsclass.
- Update the CreationDate and ModDate in the embedded PDF asset to new timestamps.

## 2025-04-03 - 4.1.0 - feat(ZUGFERD)

- Introduce dedicated ZUGFERD decoder, encoder, and validator implementations
- Update factories to use ZUGFERD-specific classes rather than reusing FacturX implementations
- Enhance PDF XML extraction by consolidating multiple extractor strategies
- Update module exports and documentation hints for improved testing and integration

## 2025-03-20 - 3.0.1 - fix(test/pdf-export)
Improve PDF export tests with detailed logging and enhanced embedded file structure verification.

- Log original PDF size and compute size increases per export format
- Print a table of format-specific PDF size details
- Verify the PDF catalog contains the 'Names' dictionary, 'EmbeddedFiles' entry, and a valid 'Names' array
- Ensure type safety for export format parameters

## 2025-03-20 - 3.0.0 - BREAKING CHANGE(XInvoice)
Refactor XInvoice API for XML handling and PDF export by replacing deprecated methods (addXmlString and getParsedXmlData) with fromXml and loadXml, and by introducing a new ExportFormat type for type-safe export. Update tests accordingly.

- Removed usage of addXmlString and getParsedXmlData in favor of XInvoice.fromXml and loadXml for XML processing.
- Added ExportFormat type and enforced type-safety in exportXml and exportPdf methods.
- Updated test files to adapt to the new API, ensuring proper error handling and API consistency.
- Revised expectations in tests to check for new methods (loadXml, validate, exportXml, exportPdf) and properties.

## 2025-03-20 - 2.0.0 - BREAKING CHANGE(core)
Refactor contact and PDF handling across the library by replacing IContact with TContact and updating PDF processing to use a structured IPdf object. These changes ensure that empty contact objects include registration details, founded/closed dates, and status, and that PDF loading/exporting uniformly wraps buffers in a proper object.

- Updated createEmptyContact (renamed in documentation to reflect TContact) to return a complete TContact object with registrationDetails, foundedDate, closedDate, and status.
- Modified loadPdf and exportPdf in XInvoice to wrap PDF buffers in an IPdf object with name, id, and metadata instead of using a raw Uint8Array.
- Replaced IContact with TContact in FacturXEncoder, FacturXDecoder, and XInvoiceDecoder to standardize contact structure.
- Aligned address and contact data across decoders and encoders for consistency.
