0.99.18.1

• Stata.file() now supports importing files in recent Stata formats (dta relelease 117, 118, 119 - see https://www.stata.com/help.cgi?dta). Also loading Stata files with mismatching encoding of value labels should now work.
• New functions Groups(), withGroups(), and withinGroups() provide support for data management within groups of rows of a data frame or data set.
• A new function Reshape() is added that is an interface for reshape() but that has simpler syntax and returns data sorted in a more convenient ordering (i.e. measurements nested in individuals).

0.99.17.1

• Added syntactical sugar to manipulate annotations and attributes.
• Fixed import of value labels for string variables in 'spss.system.file'
• Fixed codebook representation of datetime items in SPSS system and portable files
• Support for date or datetime import added to 'spss.portable.file'
• Support for date or datetime import added to 'spss.system.file'

0.99.16.3

• Visibility of binary code symbols is correctly handled for R releases 3.3.0 through 3.3.3
• Dollar and double-bracket operators for 'importer' objects are defined to facilitate
  creating codebooks for individual variables.

• Fixed 'format_html' for codebooks of data frames with factors.

0.99.16.1

• The 'subset' method for 'importer' objects now accepts the names of
  variables to be selected also as a character vector.

0.99.16

• A function codeplan() creates a data frame describing the structure of an "importer" or "data.set" object. It is possible to copy this so described structure from one "data.set" object to another or to a data frame.
