Release notes from openPMD-api

0.9.0-alpha: Improved Builds and Packages

2019-07-25T16:24:00Z

This release improves PyPI releases with proper declaration of build
dependencies (use pip 19.0+). For Makefile-based projects, an
openPMD.pc file to be used with pkg-config is added on
install. RecordComponent now supports a makeEmpty method to
write a zero-extent, yet multi-dimensional record component. We are
now building as shared library by default.

Thanks to Axel Huebl, and Franz Poeschel for contributing to this
release!

0.8.0-alpha: Python mpi4py and Slice Support

2019-03-09T16:59:58Z

We implemented MPI support for the Python frontend via mpi4py
and added []-slice access to Record_Component loads and
stores. A bug requiring write permissions for read-only series
was fixed and memory provided by users is now properly checked
for being contiguous. Introductory chapters in the manual have
been greatly extended.

Thanks to Axel Huebl, and Fabian Koller for contributing to this
release!

0.7.1-alpha: Bug Fixes in Multi-Platform Builds

2019-01-23T14:44:00Z

This release fixes several issues with libstdc++ (e.g. on OSX),
cross-compiles and modern compilers.

Thanks to Axel Huebl, and Ray Donnelly for contributing to this
release!

0.7.0-alpha: JSON Support, Interface Simplification and Stability

2019-01-11T12:49:33Z

This release introduces serial JSON (.json) support. Our API has
been unified with slight breaking changes such as a new Python module
name (import openpmd_api from now on) as well as re-ordered
store/loadChunk argument orders. Please see our new
"upgrade guide" section in the manual how to update existing scripts.
Additionally, many little bugs have been fixed. Official Python 3.7
support and a parallel benchmark example have been added.

Thanks to Axel Huebl, Franz Poeschel, Sergei Bastrakov, and
Ray Donnelly for contributing to this release!

0.6.3-alpha: Reading Varying Iteration Padding Reading

2018-11-12T11:33:26Z

Support reading series with varying iteration padding
(or no padding at all) as currently used in PIConGPU.

Thanks to Axel Huebl for contributing to this release!

0.6.2-alpha: Python: Relax Strides Further

2018-09-24T22:10:03Z

A regression in the last fix for python strides made the relaxation
not efficient for 2-D and higher.

Thanks to Axel Huebl for contributing to this release!

0.6.1-alpha: Relaxed Python Stride Checks

2018-09-24T00:27:08Z

Python stride checks have been relaxed and one-element n-d arrays
are allowed for scalars.

Thanks to Axel Huebl for contributing to this release!

0.6.0-alpha: Patches, Const Scalars, Py Containers

2018-09-20T06:38:55Z

Scalar records properly support const-ness. The Particle Patch load
interface was changed, loading now all patches at once, and Python
bindings are available. Numpy dtype is now a first-class citizen
for Python Datatype control, being accepted and returned instead
of enums. Python lifetime in garbage collection for containers such
as meshes, particles and iterations is now properly
implemented.

Thanks to Axel Huebl and Fabian Koller for contributing to this
release!

0.5.0-alpha: Refactored Type System

2018-09-17T13:27:14Z

The type system for Datatype::s was refactored. Integer types are
now represented by SHORT, INT, LONG and LONGLONG as
fundamental C/C++ types. Python support enters "alpha" stage with
fixed floating point storage and Attribute handling.

Thanks to Fabian Koller, Axel Huebl and Franz Poeschel for
contributing to this release!

0.4.0-alpha: Improved output handling

2018-08-27T21:08:32Z

Refactored and hardened for fileBased output. Records are not
flushed before the ambiguity between scalar and vector records are
resolved. Trying to write globally zero-extent records will throw
gracefully instead of leading to undefined behavior in backends.

Thanks to Fabian Koller and Axel Huebl for contributing to this
release!
