Version 4.04.04

Main changes:

• Changed default temporal-blocking angles to be minimal instead of fold-multiples. New option -no-round_up_temporal_angles will restore old behavior.
• Added temporal blocking to 2D wave example code.

Version 4.04.03

• Re-enable printing of option values in YASK compiler and kernel test utility.
• Change default value of early-load option for offloading.

Version 4.04.02

• Improve performance of all "in_slice" APIs.
• Fix some offload bugs.

Version 4.04.01

Patch to work around issue in Intel MPI 2021.10.0.

Version 4.04.00

Most important changes:

• Add reduction APIs.
• Add 2D wave and shallow-water example applications.
• Add data-type specific APIs for getting and settings YASK var data.

Version 4.03.00

Major changes:

• Add ability to provide domain and step conditions on scratch vars.
• Add wave2d and swe2d example stencils.
• Improve performance of graph algorithms in compiler.
• Allow scratch-var memory to be reused based on var lifetimes.
• Remove support for vector clustering.
• Remove support for read-ahead.
• See README.md for backward-compatibility notices.

Version 4.02.03

Main changes:

• Some bug fixes and cleanup in the YASK compiler.
• Added a few more options to the yask.sh script.
• Added some more columns to the output script.
• Added node and rank counts to the log filename.

Version 4.02.00

Use Slurm vars in yask.sh to set number of tasks and calculate OMP threads.

Version 4.01.02

• Update copyright.
• Several small-ish bug fixes.

Version 4.01.00

• Several new APIs for solutions, vars, and cross-rank MPI functions.
• Fixed some bugs in APIs when accessing scalar vars.
• YASK compiler now uses same C++ command-line parser as kernel, which is now documented in APIs.
