v1.11.0

• Added new entropy helper methods: entropy_probabilities,
  entropy_per_symbol, minimum_entropy_per_symbol,
  collision_entropy_per_symbol, entropy_total, minimum_entropy_total, and
  collision_entropy_total to lib/more_math/entropy.rb
• Replaced the old entropy method with an alias to entropy_per_symbol
• Updated documentation for entropy_ratio to clarify the size: keyword
  argument
• Removed the entropy_ratio_minimum method and its corresponding test cases
  from the codebase
• Enhanced test coverage in tests/entropy_test.rb with new unit tests for the
  added helper methods
  • Updated existing test assertions to use assert_in_delta for
    floating-point comparisons
  • Added descriptive comments to the test setup method
  • Ensured all new methods return correct values for empty, uniform, and
    varied symbol strings
• Corrected example values in entropy_ratio documentation

v1.10.0

• Added new entropy_maximum method to calculate theoretical maximum entropy
  for a text given an alphabet size
• Made size parameter required in entropy_ratio and entropy_ratio_minimum
  methods instead of defaulting to text.size
• Updated YARD documentation to clarify that size parameter represents
  alphabet size
• Modified examples to use explicit alphabet sizes for better clarity
• All entropy methods now consistently return values in bits as expected for
  Shannon entropy
• Updated documentation examples to use simplified method calls without
  MoreMath::Entropy prefix
• Enhanced entropy_maximum method documentation to explain its use in
  determining security strength for tokens
• Added comprehensive tests for entropy_maximum function covering edge cases
  and various alphabet sizes
• Improved entropy_maximum method signature to return 0 for invalid
  alphabet sizes (≤ 1) and use Math.log2 for calculation
• Updated existing entropy method documentation to clarify it calculates
  entropy in bits
• Simplified example code in documentation to use direct method calls instead
  of module prefixes

v1.9.0

• Added support for array inputs in entropy calculation methods by checking
  text.respond_to?(:chars) and using raw arrays when appropriate
• Added MoreMath::Entropy.entropy_ratio_minimum method to provide
  conservative lower bound accounting for sampling error
• Updated entropy_ratio method to use text.size instead of
  text.each_char.size for consistency
• Added comprehensive tests for new minimum entropy
  ratio methods

v1.8.0

• Extended MoreMath::Functions module with Entropy and Lambert modules
  using extend instead of include
• Added tests for entropy_ratio and lambert_w method inclusion/extension
• Updated test execution command to use bundle exec
• Updated gem dependencies and version requirements:
  • Updated rubygems version requirement from 4.0.2 to 4.0.3
  • Changed gem_hadar development dependency from version constraint "~>
    2.10" to ">= 2.17.0"
  • Maintained compatibility with Ruby 2.0 and later versions
• Added changelog configuration to Rakefile with filename set to CHANGES.md
• Updated Ruby version from 4.0-rc-alpine to 4.0-alpine

v1.7.0

• Added MoreMath::Lambert module with lambert_w method for principal branch
• Integrated MoreMath::Lambert into MoreMath::Functions module
• Included comprehensive test suite in TestLambertW class
• Added YARD documentation with examples and parameter descriptions
• Required more_math/lambert in more_math/functions.rb
• Supported special cases: W(0)=0, W(∞)=∞, W(-1/e)=-1
• Verified solution property: W(y)·e^(W(y)) = y
• Handled domain error for y < -1/e with NaN return
• Used MoreMath::NewtonBisection for robust numerical root finding
• Tests cover values: 0, 1, 100, 0.1, 1000 with expected results
• Tested convergence verification and edge cases
• Updated bundle update command to bundle update --all in .all_images.yml
• Added ruby:4.0-rc-alpine image configuration to .all_images.yml
• Added lib/more_math/lambert.rb to s.extra_rdoc_files and s.files in more_math.gemspec
• Added tests/lambert_test.rb to s.test_files in more_math.gemspec
• Updated s.rubygems_version from 3.6.9 to 4.0.2 in more_math.gemspec
• Updated s.add_development_dependency for gem_hadar from "> 2.7" to "> 2.10" in more_math.gemspec
• Added openssl-dev to the list of packages installed by apk add in .all_images.yml
• Rely on test_helper requiring more_math

v1.6.0

• Configured workflow to use Ruby 3.4 for documentation builds and deploy
  to GitHub Pages on master branch pushes
• Added context_spook as development dependency for YARD documentation
• Added cscope.out to .gitignore and updated Rakefile to include it in
  the ignore list
• Added code_indexer configuration to .utilsrc with a list of gems

  ostruct, rake, stringio, sync, test-unit, and tins
• Added doc and .yardoc directories to gitignore and rake configuration
• Updated homepage URL to escape underscore character for proper rendering
• Updated gem_hadar development dependency from version 2.4 to 2.6
• Modified package_ignore in Rakefile to explicitly include .github and
  .contexts directories instead of using glob pattern *.github/**/*
