Changes in version 2020-06-26 - Modernization and patches to C++ code to address warnings on gcc-10 - Copyright and Credit information for known all APPL contributors and other included sources. Changes in version 2019-04-10 - patch memoization - resolve several compiler warnings - use BH package for boost headers instead of packaging with appl code Changes in version 2018-11-29 - Added a NEWS.md file to track changes to the package. - Uses a memoization strategy in caching sarsop results. This deprecates the previous behavior where sarsop runs would be set to eval=FALSE and results manually loaded from cache with meta_from_log and alpha_from_log. Just call sarsop again to get load output from cache, if parameters (call signature) matches any available cache that will be loaded instead. - Uses processx to control execution of sarsop C++ code. Changes in version 0.6.16 (2025-04-16) - Another patch on Cassandra parser compatibility with modern clang checks. Changes in version 0.6.15 (2024-06-25) - Remove CXX=CXX11 from Makevars. This should also fix problems with CRAN special check setups. Changes in version 0.6.14 (2023-01-10) - Patch for Apple's sprintf -> snprintf requirements Changes in version 0.6.13 (2022-10-19) - Patch for Apple M1's clang-15 derivative. Changes in version 0.6.12 (2022-10-12) - Patch for Apple M1's clang-15 derivative. Apple seems not to contain GNU_LIBRARY-flavored stdlib, triggering alternate definitions which did not match templates. Not all platforms are consistent with the signatures of getenv() / getopt(), let's hope Apple's clang is as least. Changes in version 0.6.11 (2022-10-10) - Additional patch for compatibility with new warnings on clang-15 + R-devel Changes in version 0.6.10 (2022-09-08) - Additional patch for compatibility with new warnings on clang-14 Changes in version 0.6.9 (2021-08-05) - Additional modifications for compatibility with new clang-12 warnings Changes in version 0.6.8 (2021-02-03) - Additional modifications attempted for Solaris compatibility. Changes in version 0.6.6 (2020-12-12) - Avoid architecture-sensitive caching checks on CRAN Changes in version 0.6.4 (2020-07-19) - Indicate no solaris support via SystemRequirements Changes in version 0.6.3 (2020-06-26) - Additional CRAN patches for Solaris and additional warnings.
