# Changelog¶

All notable changes to this project after version 1.0.1 will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).

## [v2.1.1]¶

Changed - Bugfix to handle NaN values in parsed entries.

• Removed fermi_level and symmetries are removed from default misc quantities to avoid stalling relaxation jobs etc.

• Fix to the DOSCAR parser to not fail when spin-orbit couplings have been enabled.

• Fixes the convergence workchain so that a final relaxation is possible.

• Fixes the convergence workchain lack of the structure not being exposed as an input.

• Fixes the convergence workchain in cases where a plane wave cutoff was supplied, the plane wave convergence tests were still executed.

• Fixes parsing of DOSCAR when the data for the partial density of states is not available.

• Removed version pinning on postgresql install for GitHub Action tests.

## [v2.1.0]¶

Added - The metadata.label and metadata.description is now passed from the VaspWorkChain to the VaspCalculation.

• Possibilities to skip INCAR tag validation altogether.

• Recommended plane wave cutoff and k-point grid is now set as an output on the ConvergeWorkChain.

Changed - Bugfix in the check for electronic and ionic convergence for the run status.

• Bugfix in the stream output of the vasp_output file, which is now always printed without adding redirection to the executable.

• Bugfix pertaining to the matching of POTCAR data and hash upon. Fixes import and linking issues.

• Bugfix for the passing of selective dynamics.

• Parser has been re-factored.

• Pinned AiiDA to latest available version on PyPI for the CI.

## [v2.0.0]¶

Added - A new dedicated parameter namespace incar override namespace that is to be used when utilizing the existing workchain stack to supply INCAR tags directly (needs to be valid).

• Possibility to control selective dynamics with the positions_dof flag.

• Added possibility to parse magnetization.

• Nightly test runs against AiiDA core develop.

• Symbols are properly attached to BandsData.

Changed - Updated dependencies, in particular parsevasp to enable additional parsing of streams, selective dynamics and magnetization.

• Renamed override parameter namespace from vasp to incar.

• Fixed warnings related to missing context on file open etc.

• We now instead use a positive match when copying files from the restart folder so that only the required files are copying. This removes possible failures related to the restarted job failing while the parser believes the vasprun.xml etc. is okey (but in reality is from the previous run).

• Fixed missing yaml files.

• We do not allow the install of AiiDA core 1.4.0 and 1.4.1 due to a bug that caused POTCAR to be present in the repository.

• Removed py dependencies.

## [v1.0.1]¶

This is to be consider the first production release. Backwards compatibility is broken.

## [v0.3.0]¶

This is a major rewrite to be compatible with AiiDA core beta release. Backwards compatibility is broken.

## [v0.2.4]¶

Added - vasp.base workchain which transparently calls through to the ‘vasp.vasp’ calculation and restarts if appropriate.

• restarting conditions are minimal yet (only submission failed will trigger a retry)

• vasp.relax workchain which specializes in structure relaxation and optionally iterates until the structure converges.

• ‘vasp.calc.immigrant’ added in order to support VASP import Aiida-external jobs.

Changed - PotcarData.get_potcars_from_structure() now returns an entry for each kind.name in the structure, not one per kind.symbol

• PotcarData.get_potcars_dict() no longer fails if there is more than one PotcarData with the same full name in the family

• Minor changes in parser.

## [v0.2.3]¶

Changed - fixed POSCAR writing (was writing ‘direct’ followed by cartesian coordinates)

Removed - pruned outdated parts of documentation

## [v0.2.2] - 2018-03-15¶

• PyPI description and keywords updated

## [v0.2.1] - 2018-03-12¶

Added - Allow Structures which do not have sites of same element grouped

• Allow using different potentials for atoms of same element in a structure

• VaspCalculation’s settings input now accepts poscar_precision key to set maximum precision for coordinates in POSCAR

• This can be indicated in the structure by adding sites with same symbol but different name.

• io.poscar.PoscarIo, POSCAR writer replacing pymatgen one, to be replaced by parsevasp.

Changed - Use always the same order for species in POSCAR and POTCAR - POSCAR float precision default changed to 10 decimal places

## [v0.2.0] - 2018-03-07¶

Added - data.potcar.PotcarData (vasp.potcar) & data.potcar.PotcarFileData, replacement for PawData

• PotcarData is shareable, holds no licenced data

• PotcarFileData holds the licenced POTCAR file

• io.potcar.PotcarIo, handle conversion between File and DB representation of POTCAR information

• io.potcar.MultiPotcarIo, handle concatenation and splitting of POTCAR files containing multiple potentials

• verdi data vasp-potcar, CLI for importing and exporting POTCAR files

• uploadfamily, loads a set of POTCAR files into the db

• exportfamily, creates a compressed archive of POTCAR files in a family

• listfamilies, list existing POTCAR families

• io.outcar.OutcarParser, parses some information from OUTCAR file

• calcs.VaspCalculation and descendants

• inputs: settings:ParameterData additional settings that are not passed to VASP but to parsers etc

Changed - calcs.VaspCalculation and descendants

• inputs: paw:PawData -> potentials:PotcarData

• parsers.vasp.VaspParser, redesigned

• parses OUTCAR too (or tries to)

• takes parser_options that can be given in the settings input in a VaspCalculation

• renamed data.paw.PawData -> data.paw.LegacyPawData

• LegacyPawData can not be stored or changed (read-only)

Removed - io.potcar.PawParser

Deprecated - PawData is deprecated and has been renamed LegacyPawData, it can be used to read PawData database objects.
