v2.0.1

Bug Fixes

• ChainedHashTable: Implement GetEnumerator() (was throwing NotImplementedException)

Code Quality

• Resolve all 85 xUnit analyzer warnings with proper assertion methods
• Remove warning suppression from test project
• All 623 tests pass with zero warnings

v2.0.0

Breaking Changes

• Target framework upgraded to .NET 10.0 (was .NET Core 2.0)
• DLinkedList.InsertAfter now correctly inserts after index (was before)
• SkipList sentinel bugs fixed - Contains(0) on empty list now returns false
• BellmanFord iteration count fixed (V-1 iterations, was V-2)

New Features

• OpenScatterHashTable fully implemented (was all NotImplementedException)

Bug Fixes

• ChainedHashTable.CopyTo index increment bug
• SkipList level generation always >= 1 (fixes items not being added)
• SkipList sentinel node matching (fixes false positives for default values)
• BinomialMinHeap size tracking in merge operations
• BellmanFord optimality check for unreachable vertices

Other

• Modernized test suite with xUnit best practices (620+ tests)
• Updated all dependencies to latest versions
• CI/CD workflow improvements with matrix builds

v1.0 Release

First stable release of C# Algorithms.
