v1.5.1

Version 1.5.1 -- January 1, 2021

Minor Enhancements

• This is a minor enhancement release, but is a major step toward
  further portability of the ParaMonte library. All ParaMonte kernel
  library dependencies are now properly handled and recognized at runtime
  without such aggressive actions as permanently redefining the environmental
  path variables, most importantly, PATH and LD_LIBRARY_PATH on Linux/macOS.

• The ParaMonte kernel routines are now capable of handling user-input
  file paths that contain white-space (blank) or other exotic characters.

• The Bash build script for the ParaMonte C/C++/Fortran examples can now handle
  file paths that contain white-space (blank) or other exotic characters.

• The shared (dynamic) library file naming convention is now changed from
  using "dynamic" in the file name to using "shared" in the file name.

• Typo-fixes in the documentation of the library.

v1.5.0

Version 1.5 -- Dec 17, 2020

Major Enhancements

• This version introduces numerous performance and accuracy enhancements to the ParaMonte library.
• The entire kernel library is now fully documented and verified with over 866 tests that cover close
  to 100% of all lines and functions in the kernel.
• New prebuilt libraries with GNU compilers and Open-MPI on Linux and macOS are added.
• New flags are now added to the build scripts of the library that automate the process of code coverage generation.
• The testing builds are now removed from the ParaMonte release page as this build is mostly useful for development purposes.
• The issue of Windows file locking, that led to the occasional crashes of the
  ParaDRAM and ParaDISE simulations in multiChain parallelism mode, is now resolved.

Minor Enhancements

• Minor enhancements to the ParaMonte C/C++/Fortran example build scripts build.sh and build.bat.
• The default build settings are now limited to heap memory allocation with dynamic library builds
  for only serial and MPI parallelization for all languages. The stack memory allocation results in
  a ~10% gain in the efficiency of the code. The benefits of stack-memory builds are marginal and are
  often problematic, in particular, for usage with non-compiled languages. However, users can still
  build the library with stack memory allocation by specifying the appropriate build flags with
  the install.sh on Unix or install.bat script on Windows systems. For further information,
  see the installation guidelines on the ParaMonte documentation website.
• All temporary array creations in debug mode are now resolved,
  except when Intel compilers are used, in which case, the debug warning messages are silenced.

v1.4.1

Version 1.4.1 -- November 15, 2020

Enhancements

• The ParaMonte C/C++/Fortran example build scripts build.sh and build.bat
  now check for the existence of both Intel and GNU compilers in the appropriate
  order that is automatically inferred at the compilation time. Also, the dependencies
  on the MPI compiler wrappers is now removed as the MPI libraries are not required to
  build the ParaMonte examples, even in cases of parallel ParaMonte example builds.

v1.4.0

Version 1.4.0 -- October 29, 2020

Enhancements

• The IO debugging info of all ParaMonte samplers have been enhanced.
  In cases of wrong syntax or syntax-breaking input values in the simulation
  output files, the error messages are now more informative and point directly
  to the exact location of of error in the input file.

• The Integrated Autocorrelation (IAC) for sample refinement in ParaDRAM
  sampler of ParaMonte is now set to the average of all variables' IAC values
  instead of the maximum IAC value. This will lead to less aggressive decorrelation
  of the final sample, which means significantly larger final sample sizes, without
  compromising the i.i.d. property of the final refined sample. This behavior can
  be reversed back to the original by specifying "max" or "maximum" along with
  the requested refinement method, SampleRefinementMethod = "batchmeans max"
  or SampleRefinementMethod = "BatchMeans-max" (case-insensitive).

v1.3.0

Version 1.3.0 -- October 10, 2020

Enhancements

• A new simulation specification overwriteRequested has
  been added to all ParaMonte samplers. If TRUE and the
  ParaMonte sampler detects an existing set of old simulation
  output files in the output path of the current simulation with
  the same names as the output file names of the current simulation,
  then, the ParaMonte sampler will overwrite the existing simulation files.

Version 1.2.0

Version 1.2.0 -- September 22, 2020

Enhancements

• The post-processing report in the output report file
  of ParaDRAM simulation has been significantly improved:

  • The parallel simulation summary now also provides the
    predicted strong-scaling speedup behavior of the parallel
    ParaDRAM simulations in "single chain" parallelism mode.
    This can help make wiser decisions regarding the the number
    of processors for similar parallel simulations in the future.

• The ParaDRAM restart output file in ASCII mode now contains all
  proposal updates, including the first user-specified proposal specs.

• All parallel simulations now avoid the unnecessary creation of
  temporary files by all processors for System and OS operations.
  This is particularly important for large-scale parallel simulations.
  As a side effect, this will also potentially improve the runtime
  performances of the simulation.

• Major enhancements has been made to the parallel simulation
  performance analysis reported in the post-processing section
  of the ParaDRAM simulation output _report.txt files.

• The ParaMonte C/C++ build processes are now separate from each other.
