SWI-Prolog Changelog from version 9.2.5 to 9.2.6$$$[Jul 24 2024]$$$$$$BUILD: Added CMake options SWIPL_CC and SWIPL_CXX This selects the defaults for the c_cc and c_cxx flags. Distributions should normally set these to the common C and C++ compiler of the platform. Local builds typically leave them default; setting these flags to the same as used to build SWI-Prolog.

Some headers define this as returning `z_crc_t*` without defining this type while others (Fedora 40) defines the function as `uint32_t*` and defines z_crc_t. This patch makes CMake check for the z_crc_t type and; if defined; use this definition.$$$[Apr 30 2024]$$$$$$DOC: write_term/2: document interaction between portrayed and numbervars$$$FIXED: Do not name binding variables if the answer options to not handle $VAR(N)$$$Package clib$$$[May 5 2024]$$$$$$CLEANUP: Use unsigned integers for bitmaps Avoids undefined shifts and makes the code more readable.$$$Package http$$$[May 19 2024]$$$$$$DOC: Server-sent events support$$$[May 17 2024]$$$$$$ADDED: Support for server-sent events These patches allow for streaming output which is enabled by default if the content-type is text/event-stream.

This was due to a conflict over the predicate flags. As the flags field was widened; we can avoid these problems.$$$[Apr 10 2024]$$$$$$FIXED: WASM: fix fid arg position in this.query call in __call_yieldable$$$FIXED: #1262 upcase_atom/2 and friends on ISO -> wide If input is ISO-Latin-1 and the converted character requires wide characters the system trapped an assertion error. Now correctly converts to wide characters.$$$FIXED: Clang handling of max_integer_size Clang cannot handle setjmp()/longjmp in PL_next_solution(); but it can in the simple evalExpression() function. This does not have measurable impact on performance; so we enabled this as default. This fixes limiting the integer size for WASM and Clang builds on Linux. This problem did not surface on the MacOS version.$$$[Apr 8 2024]$$$$$$FIXED: comparison of MPZ and MPQ with 64 bit integers if long is 4 bytes$$$FIXED: Normalize LibBF numbers created from 64 bit integers on VS2022 VS2022 does not support 128-bit integers and therefore we must use 32-bit limbs$$$[Apr 6 2024]$$$$$$COMPAT: Introduce abstract types for PL_new_hash_table() and friends Rather than hard coded void* we now use table_key_t and table_value_t. These types are also introduced in the development series; where the type changes.$$$Package cpp$$$[Apr 2 2024]$$$$$$MODIFIED: PL_get_integer() no longer accepts floats$$$Package http$$$[Apr 24 2024]$$$$$$MODIFIED: library(http/http_load) to verify certificates This library allows for loading files from http/https URLs. It used to skip certificate checking.

Therefore we need to reset the locale after initializing Prolog in case the environment prescribes a locale with a different decimal separator; such as fr_FR.

Another possible fix is to turn such references into direct term references. That avoids local stack references; but as this is only used around GC and GC itself uses local stack reference pointers; there is little to gain.$$$[Mar 27 2024]$$$$$$FIXED: unifiable/3 internal consistency Unifiable did not correctly handle stack resizing. This is detected when running using chk_secure. Not sure whether it can also cause real issues; but the new code is simpler and safe.$$$[Mar 26 2024]$$$$$$FIXED: powm/3 function: wrong type check on 3rd argument.$$$FIXED: Declaration of term stack for evaluating expressions$$$FIXED: Write bignums when inside arithmetic. Should normally not be needed; but debugging is much easier if we can.$$$[Mar 25 2024]$$$$$$PORT: Avoid spurious warnings from spoiling pthread_setname_np() test This used to use -Werror to ensure a compiler failure if the number of arguments do not match the prototype; but this is already enforced in todays compilers.$$$FIXED: use_module/2 with except and reexport/2 with except to print warning These predicates failed if the source did not export the excluded predicate. Now it prints a warning and ignores the non-existent predicate.$$$$$$[Mar 24 2024]$$$$$$FIXED: Another fileno issue.$$$ADDED: library(sandbox): allow for Dict.get(key;Default)$$$FIXED: Stream initialization for swipl-win Was broken since recent changes keeping track of fileno.

Not entirely sure this is our mistake or within GCCs claim to work with the extended float registers. Bottom line is that comparing a double (from memory; so 64 bits) to the result of a computation may return non-equal even if the extended float when forced to 64 bits is equal.
