2017-04-15 version 2017a
- Improved parsing for the member-of relation, on both
  the left- and right-hand side of hansl statements
- Calendar: ensure that the Gregorian calendar is used
  consistently but add some optional support for handling
  Julian dates (also add a User's Guide chapter on this)
- xls, xlsx, ods and gnumeric data importers: handle string
  data (this facility extended from the CSV importer)
- Remove obsolete Kalman-filter interface
- Sequential numbering of models: skip models estimated
  with the --quiet flag and also those estimated within
  functions
- Deprecate "=" as obsolete synonym for boolean "==" 
- New functions kmeier() and naalen() for nonparametric
  estimation of survivor and hazard functions
- Add normtest() function: works much like the "normtest"
  command, but handles vectors as well as series
- Add ecdf() function to compute the empirical CDF for a
  series or vector
- New function npcorr() for nonparametric correlation, 
  either Kendall's tau or Spearman's rho
- bwrite() function for writing bundles as XML: support
  gzip compression if the filename has the ".gz" extension
- typeof() function: document it, and extend it to cover
  members of bundles and arrays
- "include" command: make it respect the "catch" flag, and
  add a --force option to force re-reading of gfn files
- "corr" command: add a --plot=filename option; also add
  --matrix option to take data from a named matrix
- "gnuplot" and "plot" commands: add a --font option
- "fcast" command: in the case of the --rolling option,
  accept the name of a scalar variable for the steps-ahead
  argument; also respect the last observation specification
  in all cases
- "tsls" command: calculate Sargan test in overidentified
  case even when there are no endogenous regressors, to allow
  "difference in Sargan" test
- "modtest" command with --autocorr or --arch option, as
  applied to VAR/VECM: switch from per-equation tests to
  multivariate tests as described in Lutkepohl's 2005 book,
  but add a --univariate option to give per-equation tests
- "var" and "vecm": enable the --window (-w) option to show
  results in a window from script execution
- "hausman" command: add options --nerlove and --matrix-diff
  to inflect the random effects estimator and calculation
  of the Hausman test statistic
- Principal Components window in GUI: support selection of
  a specific number of components to save as series
- ARMA models in GUI: add menu item to view plot of spectrum
  versus sample periodogram
- Fix bug: functions failing to return loop-index value
- Fix bug: couldn't assign to an array member of a bundle
- Fix bug: multiple X-Y scatterplots could fail when using
  long variable names
- Fix bug: the matrix-oriented version of the "restrict"
  command would fail when only the constant was restricted
- Fix bug: reading of gzipped matrix files via mread() was
  much slower than necessary for large matrices
- Fix bug: couldn't read .mat (matrix) files generated by R
  on Windows when they contained NaN values
- Fix bug: closing the function package browser while a
  package is running could cause a crash
- Fix bug: possibly misaligned labels when doing a group-
  means scatterplot using panel data
- Fix bug: "outfile" command with --buffer option was
  failing on MS Windows
- Update documentation for inlist() function
- Update translated Command Reference PDF files for Italian
  and Portuguese
- Add Galician (Galego) translation of the online Function
  Reference
- User's Guide: add a chapter on degrees of freedom
  correction for standard errors and related statistics
- Build for Mac OS X: update the bundled GTK stack
- Builds for MS Windows: update compiler to gcc 5.4.0
