highs_available_solver_options() now enumerates the
bundled library’s own option registry at runtime
(Highs::getOptionName()/getOptionType() over
all option records via new internal
solver_option_registry()) instead of a static table
regex-scraped from HighsOptions.h – it can no longer drift
from the compiled solver. New advanced column (options
registered past HiGHS’s user-settable set,
e.g. log_dev_level). Drops pdlp_features_off,
a struct member the scrape advertised but HiGHS never registers as an
option – it was never actually settable. R/constants.R and
inst/parse_highs_options.R are retained for one release as
a cross-check (inst/tinytest/test_option-registry.R), then
will be removedhi_shim_set_quiet): the Highs constructor
banner is silenced for the enumerating instance without
capture.output(); worker-thread messages are
unaffectedR/constants.R from v1.15.1’s
HighsOptions.h (156 options; new ones include
presolve_rule_test, qp_allow_hot_start,
mip_search_simulate_concurrency,
simplex_initial_condition_check/ _tolerance,
write_matrix_image, write_hessian_image)inst/patch_min.R: drop the new unconditional
add_subdirectory(extern) (HiGHS >= 1.15 builds a shared
highs_extras library by default; the R package needs
nothing from extern/).gitmodules: record the actual bundled tag (was stale
at v1.9.0)hi_new_solver() banner filter extended for v1.15’s
second banner line (THIRD_PARTY_NOTICES.md)src/hi_shim.h is
force-included into every bundled HiGHS translation unit (C and C++),
remapping printf/stdout/stderr/
abort/exit/… tokens to package-local functions
implemented over Rvprintf/REvprintf
(src/hi_shim.cpp), with worker-thread messages queued and
drained on the R main threadtools/audit_symbols.R
replicates CRAN’s compiled-code scan on libhighs.a and
fails the build on any banned symbol; maintainer-side and OPT-IN
(R_HIGHS_SYMBOL_CHECK=strict, set by the Taskfile check
targets) – ordinary user/CRAN installs skip itinst/patch_highs.R retired to
inst/archive/; successor inst/patch_min.R
keeps only the structural patches (std::cout rewrite,
pdlp/check/examples stubs, cmake surgery) with mandatory match-count
assertions – pattern drift now stops the script instead of silently
doing nothingsetLogCallback handler is removed; HiGHS’s own console path
now lands in Rprintf (sink()- and
capture.output()-capturable), still gated by
output_flag/log_to_console; the 1024-byte
callback truncation is gone.Rinstignore (/HiGHS) instead of deleting
inst/HiGHS during configure-DNDEBUG passed explicitly to the cmake build

shipped in 1.14.0-2 its three test functions were defined but never
called (0 expectations ran); also fixed its presolve option

captured construction output so warnings carry only their real textR_message_handler now receives the solver as callback data
and prints only when output_flag is true;
