Changes in version 1.2.0                        

  - Added unit tests for all procedures
      - Added clean.parms, unifying how the input parameters in the
        results list are returned
      - Added further input checks so that all input parameters are
        checked
      - Simplified code in power.z.logistic and power.z.poisson
      - Corrected formula for Hsieh et al. (1998) in power.z.logistic
      - Added target.effect to determine effect of interest in
        power.f.ancova

                        Changes in version 1.0.0                        

  - Addition 1: ANCOVA procedures with means and contrasts (Shieh)
      - Addition 2: Exact tests for proportions (Fisher & McNemar)
      - Addition 3: Generic binomial test (with plotting feature)
      - Addition 4: Dependent correlations (Steiger)
      - Addition 5: Effect size conversion functions
      - Extension 1: Generic tests handles non-zero null (useful for
        equivalence and minimum effect testing). Some specific tests
        also allow non-zero null.
      - Extension 2: ANCOVA procedures allow R-squared adjustment (i.e.,
        Keppel and Shieh)
      - Consistent function names, population-consistent argument names
        (Greek notation) and base R consistency
      - Rigorous error checks and warnings
      - Comprehensive print utility with three-tier verbosity control
      - Minor bug fixes to plot() function

                        Changes in version 0.3.2                        

  - alternative = "less" now produce correct power rates in
    pwrss.z.prop() function. Thanks to Leszek Gawarecki for reporting
    the issue.
      - The default for p0 argument in pwrss.chisq.gofit() can now be
        overwritten. Thanks to Kate Crespi for reporting the issue.
      - Type 1 and type 2 error plots show and print correct power
        estimates for two-tailed tests when effect size is near zero.
        Thanks to dpnichols811 (GitHub profile handle) and Adrian
        Olszewski for reporting the issue.
      - pwrss.z.corr() print correct errors with alternative = "greater"
        when in fact it is less (or vice versa). Thanks to Jarrod
        Hadfield for reporting the issue.

      - Improvements to documentation
      - Improvements to pwrss.z.med() and pwrss.f.ancova() console print
