Changes in version 0.4.4 (2026-10-16)                  

CRAN build diagnostics

  - The configure script no longer forwards R's diagnostic flags (-Wall,
    -pedantic, and related) to the bundled LadybugDB build. The vendored
    third-party sources use documented compiler extensions that produced
    significant-warning output on Debian Clang. All other configured
    flags, including optimisation, debugging, architecture, hardening,
    and sanitizer settings, are still passed through, and this package's
    own sources continue to be compiled with R's full flags.

                        Changes in version 0.4.3                        

CRAN Linux atomic runtime

  - Added a configure-time C++20 link test for LadybugDB's 16-byte
    atomic operations. The package now links libatomic only on
    toolchains that require it, fixing package loading with Debian
    Clang 23 while remaining portable to platforms that provide the
    operations natively.

                        Changes in version 0.4.2                        

CRAN compiler portability

  - Added explicit fixed-width integer declarations for bundled Thrift
    so the source builds with the stricter Clang 23 headers used by
    Debian R-devel.
  - Fixed bundled CRoaring inline linkage for Rtools/MinGW and
    restricted the MSVC structured-exception translator to MSVC builds.
  - Rtools builds now use LadybugDB's malloc-backed buffer manager,
    avoiding reliance on MSVC structured exception handling under MinGW.

                        Changes in version 0.4.1                        

CRAN portability

  - Replaced downloaded precompiled libraries with a pinned,
    checksum-verified LadybugDB source archive that is compiled by R's
    C++20 toolchain.
  - Added a small documented upstream portability patch so linked code
    does not call process-terminating functions, system RNGs, or write
    directly to stdout/stderr. Remote extension installation is disabled
    in this build, removing the native OpenSSL runtime dependency.

                        Changes in version 0.4.0                        

Engine and native safety

  - Updated the embedded engine from LadybugDB 0.15.2 to 0.20.4.
    Platform artifacts and matching headers are selected for macOS,
    Linux, and Windows and verified against pinned SHA-256 checksums.
  - Linked the upstream static library on macOS and Linux, eliminating
    the local @rpath/liblbug.dylib development failure. Windows installs
    its matching runtime DLL through install.libs.R.
  - Result, connection, and database ownership is now explicit.
    Closed-handle, live-child, finalizer, and double-close paths are
    checked natively.
  - Fixed R-devel/Windows compilation by passing explicit Rboolean
    values to Arrow external-pointer finalizers.
  - Fixed Windows loading by installing the checksum-verified OpenSSL
    runtime DLLs required by the upstream LadybugDB DLL.
  - Added a persisted 0.15.2 compatibility fixture and migration
    guidance.

Results, parameters, and types

  - as.data.frame() is repeatable and print()/format() use a bounded,
    non-consuming preview.
  - Added lb_fetch(), lb_has_next(), lb_reset(), lb_result_info(),
    lb_query_summary(), and lb_next_result() for streaming and
    multi-result queries.
  - Named parameters now require unique, non-empty names. All typed R
    missing scalars bind as database NULL, and binding failures identify
    the parameter in a typed error.
  - Added parameter support for dates, timestamps, integer64, raw bytes,
    lists, arrays, and structs.
  - Added exact DECIMAL and INT128 output, configurable INT64/UINT64
    handling, raw BLOB output, UTC timestamp handling, and structured
    INTERVAL, UNION, and recursive-path values.

R integrations

  - Added native Arrow C Data Interface export, chunked Arrow fetching,
    Arrow table registration, and lb_copy_from_arrow(). Data-frame
    loading prefers Arrow and retains CSV as an explicit fallback.
  - Added a DBI driver with connection, query, binding, fetch,
    transaction, quoting, and table metadata methods.
  - Added query timeout, interruption, transaction, scoped-connection,
    database configuration, and extension management helpers.
  - Graph conversion now handles recursive paths, empty results,
    null-leading columns, multiple labels and relationship types,
    isolated nodes, and exact internal identifiers.

Packaging

  - Removed tracked compiler output and the old bundled dylib,
    regenerated Rcpp and R documentation, and excluded development-only
    assets from source builds.
  - Added cross-platform R CMD check and native sanitizer CI jobs,
    installed examples, and extension and storage-migration vignettes.

                        Changes in version 0.2.0                        

  - Replaced the original Python/reticulate backend with native Rcpp
    bindings to LadybugDB 0.15.2.
