CHANGES IN VERSION 1.32.0
-------------------------

DEPRECATED AND DEFUNCT

    o releaseName() is now defunct on GenomeDescription objects.

    o Remove fetchExtendedChromInfoFromUCSC() and available.species().
      Both were defunct in BioC 3.14.


CHANGES IN VERSION 1.30.0
-------------------------

NEW FEATURES

    o Register NCBI assemblies:
        - mRatBN7.2
        - UMICH_Zoey_3.1
        - Callithrix_jacchus_cj1700_1.1
        - MU-UCD_Fhet_4.1 (GCA_011125445.2)

    o Register UCSC genomes:
        - rn7
        - canFam5
        - calJac4

SIGNIFICANT USER-VISIBLE CHANGES

    o UCSC hg38 genome is now based on GRCh38.p13 instead of GRCh38.p12

    o UCSC mm10 genome is now based on GRCm38.p6 instead of GRCm38

    o seqlevelsStyle() setter now issues a warning when some seqlevels
      cannot be switched.


CHANGES IN VERSION 1.28.0
-------------------------

NEW FEATURES

    o Small improvement to the Seqinfo() constructor: if the user doesn't
      supply the 'seqnames' argument when calling the Seqinfo() constructor,
      now we try to infer the seqnames from the other arguments.

SIGNIFICANT USER-VISIBLE CHANGES

    o Improve seqinfo<- documentation and error messages.

DEPRECATED AND DEFUNCT

    o fetchExtendedChromInfoFromUCSC() is now defunct (was deprecated in
      BioC 3.11)


CHANGES IN VERSION 1.26.0
-------------------------

NEW FEATURES

    o The seqlevelsStyle() getter and setter now support style "RefSeq" when
      the underlying genome is known.

    o Register a bunch of new NCBI assemblies and UCSC genomes. Use
      registered_NCBI_assemblies() and registered_UCSC_genomes() to get the
      lists of supported NCBI assemblies and UCSC genomes.

SIGNIFICANT USER-VISIBLE CHANGES

    o The seqlevelsStyle() getter and setter do a better job when the
      underlying genome is known. The new behaviors address two long-standing
      shortcomings of the old behaviors:

      - In general, the seqlevelsStyle() setter didn't know how to rename
        the scaffolds in an object. Now it does.

      - Also, for some assemblies that use unconventional chromosome naming
        conventions (e.g. Macaca_fascicularis_5.0), the seqlevelsStyle()
        getter was not able to detect the naming style and the seqlevelsStyle()
        setter was not able to rename the chromosomes. Now they both do the
        right thing.

      These improvements address these shortcomings but only in the situation
      where the underlying genome is known e.g. when 'unique(genome(x))' is
      "macFas5" or "Macaca_fascicularis_5.0". When the underlying genome is
      not known, nothing has changed.

DEPRECATED AND DEFUNCT

    o Deprecate releaseName() method for GenomeDescription objects.

BUG FIXES

    o Small fix to getChromInfoFromNCBI().


CHANGES IN VERSION 1.24.0
-------------------------

NEW FEATURES

    o Add getChromInfoFromUCSC(), getChromInfoFromNCBI(), and
      getChromInfoFromEnsembl().

DEPRECATED AND DEFUNCT

    o Deprecate fetchExtendedChromInfoFromUCSC() in favor of
      getChromInfoFromUCSC().


CHANGES IN VERSION 1.20.0
-------------------------

SIGNIFICANT USER-VISIBLE CHANGES

    o Update genomeMappingTbl.csv, the db used internally by genomeBuilds()
      and family.

BUG FIXES

    o Fix bug in seqlevelsStyle()
      (see https://github.com/Bioconductor/GenomeInfoDb/issues/3 for more
      information)

    o Fix fetchExtendedChromInfoFromUCSC("hg38"), which got broken by a
      recent change on the UCSC side
      (see https://support.bioconductor.org/p/117808/#117831 for more
      information)


CHANGES IN VERSION 1.18.0
-------------------------

NEW FEATURES

    o Add checkCompatibleSeqinfo().

SIGNIFICANT USER-VISIBLE CHANGES

    o Update genomeMappingTbl.csv, the db used internally by genomeBuilds()
      and family.


CHANGES IN VERSION 1.14.0
-------------------------

NEW FEATURES

SIGNIFICANT USER-VISIBLE CHANGES

DEPRECATED AND DEFUNCT

    o Remove 'force' argument from seqinfo() and seqlevels() setters (the
      argument got deprecated in BioC 3.5 in favor of new and more flexible
      'pruning.mode' argument).

BUG FIXES

    o Add missing Y/chrY entry in seqlevel style db for Drosophila
      melanogaster and Rattus norvegicus.


CHANGES IN VERSION 1.12.0 
-------------------------

NEW FEATURES

    o Add function standardChromosomes()

    o Seqlevels() setter now supports "fine" and "tidy" modes on GRangesList and
    GAlignmentsList objects

    o Add assembly_accessions dataset

MODIFICATIONS

    o Updated mapping table between UCSC and Ensembl to include recent builds

    o Use https instead of http to fetch stuff from NCBI

    o Replace 'force=TRUE' with 'pruning.mode="coarse"' in seqlevels() setter

    o Add 'pruning.mode' argument to the keepSeqlevels(), dropSeqlevels(), and
    keepStandardChromosomes() functions. IMPORTANT NOTE: Like for the
    seqlevels() setter, the default pruning mode is "error", which means that
    now these functions fail when some of the seqlevels to drop from 'x' are in
    use. The old behavior was to silently prune 'x' (doing "coarse" pruning)

    o Update files in data directory 

    o Updated internal functions .lookup_refseq_assembly_accession() and
    fetch_assembly_report() for speed and efficiency 

    o move some files from GenomeInfoDb/data/ to GenomeInfoDbData annotation package

BUG FIXES

    o fetch_assembly_summary() updated to work with recent changes to format of
    files assembly_summary_genbank.txt and assembly_summary_refseq.txt

CHANGES IN VERSION 1.10.0 
------------------------------

NEW FEATURES

    o Add function mapGenomeBuilds() that maps between UCSC and Ensembl
    builds. 

    o Add function genomeBuilds() that list all the available UCSC or Ensembl
    builds for a given organism[s] that can be used in mapGenomeBuilds() 

    o Add listOrganism() that list all currently available organism[s] included
    for use in genomeBuilds()

DEPRECATED AND DEFUNCT

    o After being deprecated, the species() method for GenomeDescription objects
    is now defunct

MODIFICATIONS

    o Zebra finch is removed as option for
    fetchExtendedChromInfoFromUCSC() as it is not support yet

     seqnamesOrder() internally calls Herve's function makeSeqnameIds()
   o add seqnameStyles generic and method from GenomicRanges

MODIFICATIONS

     testSeqnames -> isSupportedSeqnames
