13.34.2 Other Changes

• The performance of bagof/3 and setof/3 has been improved, expecially when the generator gives many solutions.
• In this release, the order in which bagof/3 and setof/3 enumerate solutions may be different compared to earlier releases. The solutions themselves are the same, only their enumeration order may have changed.
• On the Apple Mac platforms, both Intel and Apple silicon, only macOS 12 Monterey and newer are supported. Support for earlier versions of macOS has been discontinued. Contact us if this is a problem for you.
• The C API type spio_t_error_code changed from a 32-bit int type to the same size as SP_integer, i.e. 64-bit on 64-bit platforms. This does not affect Prolog code. This only affects (64-bit) C/C++ code, e.g. foreign functions doing Prolog I/O. In most cases this should be a source-code compatible change.
• The deprecated library(bdb) has been removed. It was replaced with library(lmdb) in release 4.7.
