Dear SICStus Prolog friend,

SICStus Prolog 4.7.0 was released TODAY.
Briefly, the new features are as follows.  Full details can be found in the Release Notes, as usual:

- library(mutarray) is new, and provides an implementation of mutable, dense arrays with constant lookup and update time for all indices in the best case.
- library(mutdict) is new, and provides an implementation of mutable dictionaries with constant lookup and update time for all keys in the best case.
- library(lmdb) is new, and provides functionality similar to the now deprecated library(bdb), i.e. persistent storage of terms on disk.
- library(clpfd) has gained a number of new constraints and new features.
- The AARCH64 is a new supported architecture on Linux (CentOS/RHEL 8) and macOS (Big Sur). These architectures are also known as ARM64 and Apple Silicon.
- Several performance improvements and bug fixes.

*** Supported versions:
*** 4.7.0 - until one year has passed after the next release
*** 4.6.0 - until August 9, 2022

Release 4.7.0 requires a new license code, which can be requested from:
