Hi Chapel community --
Cray Inc. and the Chapel open-source community are proud to announce
the release of Chapel version 1.17! This release includes the
following highlights:
* support for multiple repositories, including local registries,
within 'mason', Chapel's package manager
* tab completion for 'chpl' compiler options for bash users and
compiler suggestions for incorrect flags for all users
* significant improvements to Chapel's support for initializers, the
replacement for constructors — we now recommend that developers
writing new classes and records use initializers whenever possible
* new support for uninterpreted / multi-line strings defined using
triple quotes
* significant usability improvements for 'Owned' and 'Shared' types
* improved coercion behavior for enumerated and numeric types,
particularly when computing with real(32) values
* new library features, including:
- improvements to the 'LinearAlgebra' package, including 1-based
indexing by default, and routines for Kronecker products, Cholesky
factorization, and eigenvalue/eigenvector solvers
- joinPath(), isAbsPath(), and commonPath() routines in the 'Path' module
- Bessel functions in the 'Math' module
- new channel routines for efficient I/O: advancePastByte(), mark(),
commit(), and revert()
- increased use of error-handling in library routines
* significant performance and scalability improvements when executing
using 'ugni' communication over Cray Aries or Gemini networks
* improved navigation through Chapel's online documentation by jumping
between versions and color-coding the version number for outdated or
future versions
And of course, Chapel 1.17 contains a very large number of other
feature enhancements, bug fixes, and documentation improvements. To
