Rarr 1.7

• Added path() method for ZarrArray class that returns the location of the zarr array root.

Rarr 1.5

• Fixed bug when creating an empty array with a floating datatype. The fill value would be interpreted as an integer by read_metadata() and create and array of the wrong type.
• Fixed bug in update_zarr_array() when NULL was provided to one or more dimensions in the index argument. This was parsed incorrectly and the underlying zarr was not modified.
• Fixed bug in reading 64-bit integer arrays compressed with ZLIB or LZ4.
  The calculated decompression buffer size was too small and reading would fail. (Thanks to Dan Auerbach for the report: https://github.com/grimbough/Rarr/issues/10)
• Added support for the ZarrArray S4 class and the DelayedArray framework.
• Improvements to read and write performance.

Rarr 1.3

• Added support for using the zstd compression library for reading and writing.

Rarr 1.1

• Fixed bug when reading an array if the fill value in .zarray was null.
• Addressed bug in makevars where Rarr.so could be compiled before libblosc.a was ready. Also backported to Rarr 1.0.2. (Thanks to Michael Sumner for reporting this issue: https://github.com/grimbough/Rarr/issues/5)
• Corrected issue where fixed length string datatypes would be written with null terminators, resulting in strings that were one byte longer than the dtype value written in the .zarray metadata. Also backported to Rarr 1.0.3.
• Added support for reading and writing the fixed length Unicode datatype, and for reading variable length UTF-8 datatype.

Rarr 0.99.9

• Response it initial package review (thanks @Kayla-Morrell)
• Provided manual page examples for use_* compression filter functions.
• Add details of how example data in inst/extdata/zarr_examples was created.
• General code tidying

Rarr 0.99.8

• Patch compression libraries to remove R CMD check warnings about C functions that might crash R or write to something other than the R console. Working in Linux only.

Rarr 0.99.7

• Allow reading and writing chunks with GZIP compression.
• Add compression level arguments to several compression tools.

Rarr 0.99.6

• Allow reading and writing chunks with no compression.
• Enable LZ4 compression for writing.
• Fix bug in blosc compression that could result in larger chunks than necessary.
• Improve speed of indexing when combining chunks into the final output array.

Rarr 0.99.5

• Fixed bug when specifying nested chunks, where the chunk couldn't be written unless the directory already existed.

Rarr 0.99.4

• When writing chunks that overlap the array edge, even the undefined overhang region should be written to disk.

Rarr 0.99.3

• Allow choice between column and row ordering when creating a Zarr array

Rarr 0.99.2

• Catch bug when chunk files contain values outside the array extent.
• Add manual page issues identified by BBS

Rarr 0.99.1

• Switch from aws.s3 to paws.storage for S3 data retrieval.

Rarr 0.99.0

• Initial Bioconductor submission.

Rarr 0.0.1

• Added a NEWS.md file to track changes to the package.
