rdyncall 0.10.0 (2026-07-15)

• Restore package compilation on current R toolchains (#19).
• Update the bundled dyncall source and stop tracking generated static libraries (#19).
• Replace deprecated/internal R C API usage with public accessors where possible (#19).
• Support dynlist() for macOS dyld shared cache libraries (#20).
• Generate real on-disk R packages from DCF DynPort files via dynport() (#28).
• Improve generated DynPort packages with argument-preserving wrappers, variadic function metadata, generated help pages and a cleanup helper for the managed DynPort library (#52).
• Keep DynPort parsing isolated from already attached generated packages so rebuilding or rerunning a generated package in the same R session remains repeatable (#55).
• Preserve original C symbol names in generated DynPort packages while validating unsafe DynPort metadata and generated namespace/help output (#62).
• Support Constant and Variadic fields in DCF DynPort files, including binding variadic entries through dyncall_variadic() (#53).
• Add dyncall_variadic() for calling C variadic functions with explicit call-site vararg signatures (#35).
• Allow dynbind() to accept direct library paths and existing external pointer handles in addition to short library names (#29).
• Improve dynfind() discovery for libraries installed by common package managers, including Homebrew, MacPorts, Linuxbrew and Scoop (#31).
• Improve dynfind() discovery of the current R runtime library and avoid treating same-named directories as direct dynbind() library paths (#39).
• Add dynfind_explain() diagnostics for shared-library discovery and expand Windows library discovery coverage (#48).
• Return nested aggregate fields from $ as raw-backed struct objects so they can be reused for field access and aggregate by-value calls (#33).
• Fix cstruct() and cunion() field parsing when whitespace follows the type signature (#21).
• Store aggregate field names in the explicit typeinfo$fields$name column (#21).
• Fix DynPort union size calculation when known storage fields appear alongside opaque members, allowing SDL_Event values to be allocated from the generated SDL3 binding (#56).
• Add dedicated print methods for typeinfo, struct, ctype, dynbind.report and floatraw objects (#41).
• Add callback_status(), callback_is_active() and callback_last_error() for inspecting rdyncall callback invocation and error state (#49).
• Add by-value aggregate argument and return support to ccallback() for the implemented x86_64 and ARM64 dyncallback backends (#50).
• Add struct and union bitfield layout, access, DynPort parsing, and by-value aggregate support (#26).
• Add the rdyncall.callvm.size option to configure CallVM argument stack size at package load (#22).
• Add by-value aggregate argument and return support to dyncall() for registered struct and union types on supported dyncall backends, including ARM64 aggregate ABI handling (#23).
• Harden low-level argument validation for typed pointer signatures, packing helpers and pointer offsets (#59).
• Support fixed-size array fields in struct and union type signatures via the type[N] suffix (#26).
• Add @packed, @pack(n) and @align(n) layout directives for cstruct(), cunion() and DynPort aggregate definitions (#26).
• Refresh roxygen-generated documentation and package metadata for renewed development (#19).
• Generate NAMESPACE from roxygen2 metadata instead of maintaining it by hand (#40).
• Modernize GitHub Actions checks across Linux, macOS, and Windows, with an optional R-hub workflow for extended platform checks (#19).

rdyncall 0.9

• Update: use the latest dyncall version.
• Improve dynamic library search for Windows.
• Update package refactoring per CRAN requirements.

rdyncall 0.8

• Reimplement simplified version of dynfind().
• Add dynport: pcap.
• Minor documentation update for SDL installation on Solaris/OpenCSW.

rdyncall 0.7.5 (2012-09-12)

• Add support for new ARM ABI armhf (ARM hardfloat), tested on Raspberry Pi (armv6) and Efika MX Smartbook (armv7).
• Accept NULL for typed pointer arguments.
• Add support for *v (void*) return type signature in dyncall().
• Add support for **c and external pointers to support strptrarray().
• Change dynport containers from R namespaces to environment objects to remove .Internal calls and :: operators on dynports; dynports are unloaded via detach(dynport:<PORTNAME>).
• Improve finalizer management of callbacks.
• Add backward compatibility with R 2.10 for legacy Mac OS X 10.4/PowerPC R port.

• Add support for amd64 using Solaris tool-chain.
• Add vignette "foreign library interface".
• Fix Solaris/x64 by adding search path amd64 folder for dynfind().
