BioJava Changelog
-----------------

BioJava 6.0.0 (future release)
==============================
### Removed
* All code related to All-vs-All structural alignments db calculation and access
* JFatCatClient and all code depending on it
* PDP domain providers (depended on JFatCatClient)
* Support for retrieving structure data with prefix "PDP:" (AtomCache, StructureIO)

BioJava 5.4.0
=============
### Added

* InterfaceFinder class to find interfaces of a given PDB assembly #867
* New switch in Subunit clusterer `useEntityIdForSeqIdentityDetermination` #857 #859

### Changed
* Now genbank parser will allow 5'<3' for circular DNA #855

* Upgrade ciftools-java dependency to latest java-8 compatible release 0.7.1

BioJava 5.3.0
=============
### New features
* Support for reading structures from [binary cif format](https://github.com/dsehnal/BinaryCIF) in structure module, thanks to  [CIFTools-java library](https://github.com/rcsb/ciftools-java). Thanks @JonStargaryen 
* Reading structures from mmCIF via new parser from [CIFTools-java library](https://github.com/rcsb/ciftools-java). Much better read performance than existing parser. Both parsers still live alongside in BioJava 5.3.0, with default still being the BioJava native one. 

### Bug fixes
* 8x performance increase in reading (non-gzipped) MMTF files thanks to [mmtf-java](https://github.com/rcsb/mmtf-java) dependency upgrade to 1.0.9

* Fixes in bioassembly creation, where EntityInfo objects weren't correctly cloned and wired #825
* More efficient interface ASA calculation in NCS cases #823
* Add EntityInfo to reduced structure #822
