The issue will be fixed in the near future.



= BioRuby 2.0.1 RELEASE NOTES

Some bug fixes and improvements have been made to the BioRuby 2.0.1 after
the version 2.0.0 is released.

== Bug fixes

* Bio::GFF::GFF2::Record.parse did not return correct object.

== Improvement of sample scripts

The following scripts in the sample/ directiry are newly added.

* color_scheme_aa.rb: Example of Bio::ColorScheme for an amino acid sequence.
* fastq2html.rb: Visualization of FASTQ sequences, colored by quality scores.
* rev_comp.rb: Shows reverse-complement sequences of the given sequences.

The floowing scripts are modified to fix bug and/or to improve features.

* na2aa.rb: Completely rewritten to fix bug. Shows translated sequences.
* color_scheme_na.rb: Added support for various sequence formats.

=== CWL (Common Workflow Language) workflow files are added

CWL (Common Workflow Language) workflow files are added for some sample
scripts. The usage of each sample script will be clarified with the CWL
workflow files.

Two type of files are prepared for CWL workflow engine. *.cwl is a workflow
definition file for each sample script. *.testdata.yaml describes sample
input data for each CWL workflow.

In this version, cwl files for the 3 sample scripts are added.

* fastq2html.rb: fastq2html.cwl with fastq2html.testdata.yaml
* na2aa.rb: na2aa.cwl with na2aa.testdata.yaml
* rev_comp.rb: rev_comp.cwl with rev_comp.testdata.yaml



= BioRuby 2.0.0 RELEASE NOTES

A lot of changes have been made to the BioRuby 2.0.0 after the version 1.5.x
is released. This document describes important and/or incompatible changes
since the BioRuby 1.5.0 release.

For known problems, see KNOWN_ISSUES.rdoc.

== Features moved to separete gems

Some features are moved to separate gems because of reducing complexity
and/or to avoid external library dependency of BioRuby core.

=== BioRuby Shell is moved to "bio-shell"

BioRuby Shell is split to "bio-shell" gem.

=== Executable files are moved to "bio-executables"

To avoid unexpected loading of executable files by some Rails software,
all executable commands are moved to "bio-executables" gem
(except the "bioruby" command that is included in the above "bio-shell" gem).

=== Fast BLAST XML result parser by using Expat XML Parser is moved to "bio-blast-xmlparser"

Fast BLAST XML result parser by using Expat XML Parser is split to
"bio-blast-xmlparser" gem, because of external C library dependency.
Please install "bio-blast-xmlparser" gem if possible.
If it is installed, BioRuby automatically use it.

=== Bio::PhyloXML is moved to "bioruby-phyloxml"

Bio::PhyloXML is split to "bioruby-phyloxml" gem.

NOTE: Please uninstall "bio-phyloxml" gem, that have been created as a
preliminary trial of splitting a module in 2012 and have not been
maintained after that.

=== Bio::SQL is moved to "bio-biosql"

Bio::SQL is split to "bio-biosql" gem.


== New features and improvements

=== HTTPS is used to access NCBI web services

As you may know, NCBI announced that all HTTP resources will be switched
to HTTPS on September 30, 2016. To follow the transition, all URLs for
accessing NCBI E-utilities in BioRuby are changed to use HTTPS.

In BioRuby, the following classes/modules are affected.

* Bio::NCBI::REST and descending classes
* Bio::PubMed

In some rare cases (especially when building Ruby and/or OpenSSL by yourself
from source code), Ruby does not include SSL/TLS support, or Ruby fails to
detect SSL root certificates. In such cases, you may need to reinstall or
upgrade Ruby, OpenSSL (or alternatives), and/or SSL root certificates with
appropriate configuration options. Alternatively, installing binary packages
is generally a good idea.

=== KEGG::GENES#diseases and related methods are added

The following methods are added to KEGG::GENES, contributed by @kojix2.

* networks_as_strings
* diseases_as_strings
* diseases_as_hash
* diseases
* drug_targets_as_strings

=== Pre-calculated ambiguity codon tables in Bio::CodonTable

Pre-calculated ambiguity codon tables are added, contributed by
Tomoaki NISHIYAMA.


== Bug fixes

* Fixed a parser bug in Bio::Fasta::Report, FASTA output (-m 10) parser,
  contributed by William Van Etten and Mark Wilkinson via GitHub.
* HTTPS is used to access GenomeNet BLAST web service, contributed
  by @ramadis via GitHub.
* Bio::AAindex documentation fix, suggested by @kojix2 via GitHub.
* Suppress warning messages in Ruby 2.4 and later.


== Incompatible changes

=== Bio::Taxonomy is removed and merged to Bio::PhyloXML::Taxonomy

Bio::Taxonomy in lib/bio/db/phyloxml/phyloxml_elements.rb was written for
PhyloXML in 2009. It was intended to become general taxonomy data class in
BioRuby in these days. However, no efforts have been made to improve the
Bio::Taxonomy class, and it still remains to be a PhyloXML specific class.
Because Bio::PhyloXML is split as a different Gem (Biogem) package, we now
decide to remove Bio::Taxonomy and merge it to Bio::PhyloXML::Taxonomy.

In the codes using Bio::Taxonomy directly, changing Bio::Taxonomy to
Bio::PhyloXML::Taxonomy or adding the following monkey patch may be needed.

   module Bio
      unless defined? Taxonomy
         Taxonomy = Bio::PhyloXML::Taxonomy
      end
   end

In the future, Bio::Taxonomy might be added as general taxonomy data class.
The new Bio::Taxonomy might be incompatible with the current Bio::Taxonmy.

=== Some features are moved to separete gems

Some features are split to separete gems and removed from this "bio" gem.
See the above "Features moved to separete gems" topics for details.

== Known issues

The following issues are added or updated. See KNOWN_ISSUES.rdoc for other
already known issues.


== Other important news

=== Ruby 1.8 is no longer supported

Ruby 1.8.x is no longer supported. Though unsupported, some components
may still run on Ruby 1.8.7. Please use Ruby 1.8.7 at your own risk
with this version of BioRuby.

=== Installation without RubyGems is no longer supported

Installation by using setup.rb without RubyGems is no longer supported,
and setup.rb is no longer included in BioRuby distribution.
