CRAN v0.97.1

Minor compatibility updates to pass new and improved CRAN checks.

CRAN v0.96.4

Purpose:

• To fix a C++ issue with TBB that was causing an installation failure on
  downstream packages on ubuntu-devel environments.
• To remove some C++ code for similarity computations that is not needed
  because it is contained in the proxyC library.

CRAN v0.96.3

• A minor fix to change packageVersion() calling a numeric instead of character, following a note from CRAN.

CRAN v0.96.2

• Fixes for C++ header compatibility for existing quanteda 3.x and the forthcoming 4.0 version.
• Fixes for compatibility with Matrix >= 1.5. (#54)
• Fixed how subsetting ([) works for textstat outputs, to fix #50.

CRAN v0.96

• Fixes for compatibility with Matrix >= 1.5. (#54)
• Fixed how subsetting ([) works for textstat outputs, to fix #50.

CRAN v0.95

• Updated textstat_simil() for new proxyC version v0.2.2, which affects how similarities are returned for NA values. See #45.
• Fixed a bug in the computation of Yule's K. (#46)
• Corrected the name of similarity method "hamann" to its correct spelling (formerly "hamman", which still works too). (#44)

CRAN v0.94

• Move the S4 definitions for simil, dist, and proxy textstat classes from quanteda to quanteda.textstats.
• Changes the operation of groups in textstat_frequency() to operate as in quanteda v3.

CRAN v0.93

• Minor changes to ensure compatibility with quanteda v3.
• Changes to avoid breaking tests on older releases, caused by changes to the default for stringsAsFactors in data.frame().

CRAN v0.92

• Removed data.table dependency (#5).
• Removed older non-C++ keyness methods (#4).
• Removed code that was breaking the Solaris build on CRAN.
• Removed digest Import not used.

CRAN v0.91

• Fixes some issues causing errors on Solaris and on tests for the older R release on Windows.
• Removes problematic cacheing of results from textstat_summary() and associated functions and tests.
