Changes in version 0.2.2 (2026-02-16)                  

Bug fixes

  - Fixed rchk warnings: "Suspicious call (two or more unprotected
    arguments) to Rf_setAttrib" in pxlib_get_data_c()
    (interface.c:341, 347)

                 Changes in version 0.2.1 (2026-02-11)                  

Bug fixes and improvements

  - Fixed rchk warnings:
      - Suspicious call (two or more unprotected arguments) to
        Rf_setAttrib at pxlib_get_data_c Rparadox/src/interface.c:317
      - Suspicious call (two or more unprotected arguments) to
        Rf_setAttrib at pxlib_get_data_c Rparadox/src/interface.c:326
  - Optimized performance using local static variables for constant
    caching
      - Reduction in allocVector() calls for repeated file reads
      - Caches class vectors: c("pxdoc_t", "externalptr"), c("hms",
        "difftime"), c("POSIXct", "POSIXt")
      - Caches name vectors for metadata structure
  - Added download statistics badges to README (total, weekly, daily)

                 Changes in version 0.2.0 (2026-02-05)                  

New features

  - Encryption Support: Added the password argument to read_paradox().
    Users can now read password-protected Paradox files (.db) and
    associated BLOB/Memo files (.MB).
  - Enhanced Metadata: pxlib_metadata() now returns human-readable field
    types (e.g., "Alpha", "Date", "Memo") instead of raw integer codes.
  - Encoding info: Metadata now explicitly reports the detected
    encoding.

Bug fixes and improvements (Core C library)

  - Major x64 compatibility update: Integrated patches for the
    underlying pxlib engine to ensure stability on 64-bit systems.
      - Replaced long int with int32_t in data reading functions to
        ensure correct data width on 64-bit systems (Windows/Linux).
      - Fixed pointer arithmetic logic in src/px_head.c to prevent
        undefined behavior and header corruption.
      - Updated writeproc signature to ssize_t for POSIX compliance.

                 Changes in version 0.1.5 (2025-09-29)                  

CRAN check Note fix

  - remove incorrect CRAN link in Readme.

                        Changes in version 0.1.4                        

Cosmetic fixes

  - Add misplaced picture link at Readme.Rmd.
  - Add pxlib URL to DESCRIPTION file.
  - Fix NEWS format.

                        Changes in version 0.1.3                        

New features

  - Added a high-level read_paradox() function for a simple, one-step
    workflow to read Paradox files. This is now the recommended function
    for most users.
  - Added a pxlib_metadata() function to retrieve database metadata
    (number of records, field details, encoding) without reading the
    entire dataset.

Bug fixes and improvements

  - The architecture for handling character encodings has been
    completely refactored. The C-level code now returns raw character
    data, and all conversion to UTF-8 is handled reliably in R via the
    stringi package(ICU) instead of Riconv. This fixes test failures on
    CRAN and improves robustness for files on various operating systems.
  - Added stringi to package imports.
  - Added extensive tests for the new read_paradox() and
    pxlib_metadata() functions.
  - Documentation and examples have been updated to reflect the new
    functions and recommended workflow.

                 Changes in version 0.1.2 (2025-09-22)                  

Bug fixes and improvements

  - Fixed CRAN check issues on Debian: package no longer attempts to
    open Paradox files in write mode (rb+ → rb). This ensures full
    compliance with CRAN Policy (no writes outside of temporary
    directories).
  - Fixed heap-buffer-overflow in PX_get_data_alpha (discovered with
    AddressSanitizer). Now the function safely respects field length and
    prevents out-of-bounds reads for fixed-length strings without \0.
  - Improved handling of invalid/null Paradox dates with an upper bound
    filter for extreme values.
  - Added proper .gitignore entries for cran-comments.md and
    CRAN-SUBMISSION.
  - Updated README with CRAN badges and installation instructions.
  - Expanded test coverage: re-enabled datasets with German, English and
    Russian encodings, including CP866.

                 Changes in version 0.1.1 (2025-09-16)                  

Bug fixes and improvements

  - Fixed CRAN feedback:
    
      - Removed unnecessary \dontrun{} in examples.
        Added fast, self-contained examples using demo files
        (biolife.db, of_cp866.db in inst/extdata).
      - Ensured no commented-out example code remains.
      - All examples now run in < 5s and without commented-out code.

  - Fixed vignette build issue on CRAN check servers:
    
      - Explicitly added rmarkdown in VignetteBuilder
        to avoid failures when running with --no-suggests.

  - Memory management improvements:
    
      - Fixed memory leaks in src/interface.c when reading BLOB fields.
      - Examples and vignette now run cleanly under Valgrind.

  - Verified that all examples run in < 5 sec and vignettes build
    successfully across test environments.

                        Changes in version 0.1.0                        

  - Initial CRAN submission.
