=== kim-api-2.2.0 =============== 18Nov2020 ====================================

* The kim-api now supports Windows.  Significant additions have been made to
  the code and CMakeLists.txt files to support building kim-api and items on
  Windows via Cygwin and MinGW; Build on Windows requires C++17.
  (Thanks to Alex Stukowski)

* kim-api is now "relocatable" after install.  When installed to a non-standard
  PREFIX (with the CMAKE_INSTALL_PREFIX CMake option) the entire install tree
  may be moved, after install, to a new location in the file system and
  everything should still work.  This uses the RPATH, ${ORIGIN}, and similar
  mechanisms and is functioning on Linux, macOS, and Windows.  (This is tested
  in the CI.)

* Added 'portable-model' utility which prints out an edn dictionary containing
  information about the features and properties of a portable model.  This
  includes the list of supported compute arguments and callbacks, the
  parameters that the model makes available at runtime, etc.  The utility can
  be found in the LIBEXEC install directory.

* Added Push/PopDefaultPrintFunction to KIM::Log interface to support Simulator
  specific logging behavior such as the need for MPI communication to the head
  node for I/O operations

* Portable Model parameter files are now guaranteed to all be found in a single
  subdirectory.  This provides uniform handling of parameter files for both
  Portable Models and Simulator Models.  New GetParameterFileDirectoryName()
  and GetParameterFileBasename() routines have been added and
  GetParameterFileName() has been deprecated in the KIM::ModelDriverCreate
  interface.  A new GetParameterFileBaseName() routine has been added and
  GetParameterFileName() has been deprecated in the KIM::SimulatorModel
  interface.

* Update documentation to point to new https://matsci.org discourse OpenKIM
  forum

* Switch to minimum version 3.10 for CMake

* Complete refactor of CMake build details to improve exported target support.
  This required an update to how kim-api items define their CMakeLists.txt
  files.  This version remains backward compatible with item CMakeLists.txt
  files from older versions, but support for these is deprecated and will be
  removed in v3.

* Added human readable CMake configuration summary log (also a detailed
  version) which is printed at the end of the cmake configuration step

* Added new documentation page describing CMakeLists.txt files for the various
  kim-api item types

* Added native CMake implementation of xxd processing which allows the package
  to be build on systems without the xxd executable

* The collections-management utility will now use curl if wget is not available
  on the system

* Added a user-agent string to wget/curl commands so downloads and queries may
  be identified as coming from the collections-management utility

* Improve debugging of collections-management behavior with new CM_VERBOSITY
  environment variable and added better error messages

* Full refactoring of travis-ci, docker, and testing implementation

* Added support for openSUSE, ubuntu, centos, and debian to testing via docker

* Added ubuntu_cmake310 to explicitly test build with CMake version 3.10

* Added MinGW travis-ci testing (Thanks to Alex Stukowski)

* Added unique build identifier to default name for config and user collection
  files

* Refactor and improve handling of deprecated identifiers in configuration file

* Check for and ignore empty kim standard metadata files

* Adopted the `fprettify` Fortran code formatter and reformat all Fortran code
  to conform to the kim-api settings (now in .fprettify.rc).  Added scripts to
  support git-commit hook

* Refactor #includes to satisfy include-what-you-use linter

* Refactor initialization of pointers as best practice

* Fix a bug in C language binding for SimulatorModel Interface

* Fix a bug associated with the edn-cpp use of exceptions

* Fix issues identified by Coverity Scan

* Various fixes and improvements

* Various documentation updates

* Fix c_long overflow (for i386 systems) bug in Fortran kim_collections_module.

* Rework 'kim-api-collections-management install xxx OpenKIM' behavior.  Now
  installs the latest official release archive found at
  https://s3.openkim.org/archives/collection/.  This also greatly reduces the
  total build and install time.

* Redefine/refactor KIM::Collections behavior for finding item names.
  Previously, a shared library file was found, opened, and checked for
  validity.  To significantly improve performance, now simply the existence of
  the shared library file is used to identify available item names.

* Redefine/refactor collections-management and collections-info to remove
  '--with-version' option.

  simulators for packaging of parameter files, input commands, and metadata
  necessary to run a simulator's native potentials.

* Added new KIM::Collections interface (and the supporting extensible
  enumerations KIM::Collection and KIM::CollectionItemTypes) providing
  programatic access to the KIM API Collections and its configuration settings.
  (This included a refactor and removal of old_KIM_API_DIRS.*.)

* Convert from old 'models' to 'portable-models' nomenclature for KIM API
  collections, including environment variables, configuration file, etc.  (For
  backward compatibility, the old configuration file format is still accepted.)

* Added support for Metadata files to (internal) KIM::SharedLibrary and
  programatic access to these files from the new KIM::Collections interface.

* Automatically add standard openkim.org metadata files (kimspec.edn,
  kimprovenance.edn, and kimcite-*.bib) to an item's shared library if they
  exist.

* Significant documentation updates to describe the new interfaces as well as
  changing to the the Portable Model (PM) and Simulator Model (SM) terminology.

* Added explicit documentation of Fortran interfaces for routines called by the
  KIM API (ModelCreate, ModelDestroy, GetNeighborList, etc.).

  of strings, which are unnatural in C/C++ and allows for more natural handling
  of string arguments in Fortran. (See: KIM_API_get_NBC_method(),
  KIM_API_get_params(), and similar routines.)

  Makefile.  The conventional name for these files now ends in ".kim.tpl".

* Model ".kim" file name is now specified in the Makefile and can be anything
  the developer desires.

* Remove deprecated KIM_API_init() routine.

* Remove deprecated Fortran Cray pointer support.

  "descriptor.kim" in accordance with the new convention of the openkim.org
  processing pipeline.

* Deprecate KIM_API_init() and add KIM_API_file_init() to replace it as the
  primary openkim.org Tests should initialize the KIM API and specify their KIM
  descriptor files.

* Portability fixes for the make system

* Move away from naming various files based on the item (Model Driver, Model,
  Test) name.  Instead establish standard names for each item type.

* Improved an aspect of the api's error checking/reporting


=== openkim-api-v1.2.1 ========== 21Jul2013 ====================================


* Reverted to gnu make v3.81 from v3.82 to better represent actual needs.


=== openkim-api-v1.2.0 ========== 12Jul2013 ====================================


* Documentation updates.

* Various bug fixes.

* Added support for searching ${HOME}/.kim/ and ./ for Models and Model Drivers
  when the package is installed via the `make install' command.

* Added install and uninstall targets to the Make system.

* Now the build system (in dynamic-load and dynamic-link modes) hides all
  symbols in the Model Driver and Model libraries except for the model_init()
  function and the Model's kim descriptor string.  This means that there is no
  need to worry about symbol clashes between Models, Model Drivers, or Tests.

* Implemented dynamic-load, dynamic-link, and static-link build options.

* Make system now provides only summary information on the build process.  This
  makes the progress easier to understand.  To see the actual build commands
  use `make -n'.

* Removed `integer*8' and changed `real' and `real*8' to `float' and `double'.

* Now use -g, -Wall, and -pedantic by default for all compilations.

* Changed model_init() function conventions to simplify the scheme.  This also
  resulted in the removal of the Model or Test name from the descriptor files.

* Added the openkim-api-descriptor-file-match utility.

* Completely rewrote and streamlined the openkim-api Make system

* Changed directory names from trailing `s' to trailing `S'.

* Updated example Tests and Models to use the new get/set method routines.

* Added `const' to api string parameters to avoid warnings in Models and Tests

* Added get/set method routines to properly transfer pointers to functions
  or methods via the api.

* Added support to examples for NEIGH_RVEC_H.

* Added the NEIGH_RVEC_H NBC method.

* Added ex_free_cluster_CLUSTER_memory F90 Test which manages its own memory.

* Added ex_model_Cu_PF_Johnson C pair-functional model and template.

* Updates and bug fixes in example Models.

* Bug fixes for vc_forces_numer_deriv and added vc_config_ener_forces and
  vc_forces_delta to the distribution.


=== openkim-api-v1.1.1 ========== 19Aug2012 ====================================


* Added run_forces_numer_deriv_for_all_models script that will run and
  summarize the results of vc_forces_numer_deriv for all available Models.

* Added vc_forces_numer_deriv "verification check" that can be used with any
  Model to check the consistency of its computed forces with a numerical
  derivative based on the Model's energy.

* Fixed a bug in the MI_OPBC_* support for ex_model_Ne_P_fastLJ

* Fixed a bug in the make system that occurred when using static linking that
  would cause some Models to be incorrectly identified as "unknown"

* ex_test_*_free_cluster and ex_test_*_free_cluster_stiff now support CLUSTER
  NBC (which means they work with ALL NBC methods)

* Documentation updates

* Updated 32/64 bit switching in Fortran code for easier maintenance

* Moved library compile flags to end of command line to make sure all libraries
  are correctly associated with the appropriate .so files

* Cleaned up ex_model_driver_P_* and ex_model_Ne_P_fastLJ to simplify memory
  management and PARAM_* handling


=== openkim-api-v1.1.0 ========== 12Jul2012 ====================================


* Documentation updates

* Introduced the use of THIS_FILE_NAME in Fortran examples instead of __FILE__.
  This allows for easily setting the value of THIS_FILE_NAME to something
  appropriate (short) when the default preprocessor value of __FILE__ is longer
  that 132 characters (the max line length for Fortran)

* Changed KIM standard time unit from `fs' to `ps' to be consistent with LAMMPS
  `metal' unit system

* Changed KIM_COMPUTE and KIM_NOT_COMPUTE to KIM_COMPUTE_TRUE and
  KIM_COMPUTE_FALSE, respectively

* Removed KIM_API_MAX_NEIGHBORS; the api no longer puts any restriction on the
  number of neighbors for an atom

* Updated api and examples to always `return' with an error code instead of
  `exit' or `stop'.  This allows the Test to handle errors and is a better
  convention for error handling

* Added KIM_STATUS_MODEL_UNSUPPORTED_CONFIGURATION for cases where a
  configuration is identified at run time as unsupported

* Removed requirement for a trailing `/' in environment variables (such as
  $KIM_DIR)

* Added make warning if `make' is invoked from a Model directory when static
  linking is being used.

* Added `make examples-force' target

* `make examples' only copies files; it no longer also compiles everything

* Changed all call-back interfaces (model_init, model_reinit, model_compute,
  model_destroy) to be consistent: integer functions (in Fortran speak).  Also
  updated examples and templates to conform to this new interface.

* Added get_model_partcl_typs() and get_test_partcl_type() service routines
  Removed get_partcl_types() routine.

* Added ability of a Model/Model Driver to set its particle type codes at
  runtime

* Added support for .kimignore files in MODELS, MODEL_DRIVERS, and TESTS
  directories

* Added `Temperature' to standard.kim for "temperature dependent" Models

* New Model Driver interface supports reading from any number of files (not
  strings)

* Support for 001-999 particle types in Model Drivers

* Use $(strip ) function to avoid difficult trailing space problem in make files

* Rearranged and simplify compiler settings files
  (KIM_API/*_compiler_settings.mk)

* Changed CPPLIBFLAG to LINKLIBFLAG in Make files to better represent its use

* Many improvements to Make-system portability

* Carriage returns are now striped from kim and parameter files during Make

* Improvements to the vc_forces_numer_deriv verification check

* Bug fixes for KIM_API_init() matching

* Significant clean-up/rearrangement of core api code


=== openkim-api-v1.0.1 ========== 25Feb2012 ====================================


* Bug fix to ex_model_Ne_P_fastLJ

* Bug fix to ex_model_Al_PF_ErcolessiAdams (and associated template file)

* Documentation updates


=== openkim-api-v1.0.0 ========== 22Feb2012 ====================================


* Moved all examples to EXAMPLES directory and added `make examples' target.

* Renamed all example Model Drivers, Models, and Tests.  Now have `ex_' prefix.

* Renamed nearly all API functions to improve readability and comprehension.

* Changed KIM_API_get_half_neigh and KIM_API_get_full_neigh to just
  KIM_API_get_neigh.

* Total re-work of unit handling for the API.

* Added KIM_API_model_info() function for Tests to use for discovering what a
  Model supports.

* Added KIM_API_getm_* and KIM_API_setm_* routines to get/set multiple arguments
  in one function call.

* Added KIM_API_sting_init() for use by Tests that generate their KIM descriptor
  file "on-the-fly".

* Added process_dEdr and process_dE2dr2 approach for calculating general
  properties.  Currently automatic support for `virial', `particleVirial', and
  `hessian' is available.

* Added "unsymmetric half neighbor lists" (numberContributingParticles).

* Added model/test buffers for use by Model and Test, respectively.

* Improvements in dynamic linking setup.

* Examples additions, improvements, and bug fixes.

* Bug fixes.


=== openkim-api-v0.2.0 ========== 15Sep2011 ====================================


* Updated documentation

* Added KIM_API_report_error() service function and updated all examples
  and templates to use this function.

* Added KIMstatus.h which contains definitions of KIM status codes.

* Added KIM_API_status_msg() service routine to return a string describing a
  given status code.

* Updated messages printed to kim.log file to be more informative.

* Model KIM descriptor files are now incorporated into the Model's binary
  library file.  This means that the file is no longer required at run time and
  that the Model must be recompiled after changes to the descriptor file.

* Added Model Driver Templates

* Added two Model Drivers and four Models based on the Model Drivers

* Removed example model_Ar_P_MMorse in favor of the Morse Driver and its Models

* Added support for Model Drivers

     KIM_API_get_listFixedParams()
     KIM_API_get_NBC_method()

* Fixed bug in test_**_free_cluster.F90

* Renamed `README.git' to `README_GIT' to avoid confusion with the
  git convention that the extension `.git' refers to a bare repository

* Added support for dynamic linking

* Updated documentation

* Added documentation to the standard.kim file which now describes in detail
  the format and content of KIM descriptor files.
