v2.0.0-beta.6

fix: Const/immutable bool string conversion

v2.0.0-beta.5

1. Improved Diff Output

• Line-based diff algorithm - Uses LCS (Longest Common Subsequence) instead of naive positional comparison
• Block grouping - Consecutive insertions/deletions are grouped together
• Context lines - Shows 2 lines before/after each change block
• Clear labels - Added --- Expected (missing in actual) --- and +++ Actual (not in expected) +++ headers
• Visual separators - ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ between change blocks
• Fixed stray period - No longer adds . on its own line after multiline diffs

2. AssertResult Improvements

• Added copy constructors and assignment operators for better object management

3. Documentation & Refactoring

• Updated README with extension library usage
• Enhanced extending guide with examples
• Simplified import structure in asserts.d
• Enhanced value evaluation logic

4. Registry Operations

• Import Registry operations for enhanced functionality

v2.0.0-beta.4

• Add a precision parameter to toFloatingString for configurable decimal places

v2.0.0-beta.3

• update serializer registry to accept list types

v2.0.0-beta.2

• fix compiler error while using the project as dependency

v2.0.0-beta.1

fluent-asserts v2.0.0-beta.1

Highlights

Complete engine rewrite - v2.0 is a ground-up rewrite focused on performance, @nogc compatibility, and better developer experience. The public API remains familiar while the internals are now faster and lighter.

New Features

• @nogc support - Use fluent-asserts in @nogc contexts
• Output formats - Choose between verbose, compact (for AI tools), or TAP (for CI/CD)
• Context data - Debug loops with .withContext("key", value) and because("msg %s", i)
• Memory assertions - Test GC behavior with .allocateGCMemory() and .allocateNonGCMemory()
• Assertion statistics - Track pass/fail counts via Lifecycle.instance.statistics
• Recording evaluations - Capture assertion results with .recordEvaluation() without throwing
• Custom failure handlers - Install your own handler with setFailureHandler()
• Release build no-op - Zero overhead in release builds (like D's built-in assert)

Performance Improvements

• Lazy source parsing - Source code only parsed on assertion failure
• Small Buffer Optimization - Short strings avoid heap allocation entirely
• Reference-counted memory - Manual memory management replaces GC allocations

Breaking Changes

• Module paths changed - Internal modules moved (e.g., fluentasserts.core.operations.* → fluentasserts.operations.*)
• Serializer registry renamed - Use HeapSerializerRegistry instead of SerializerRegistry
• Operation signatures changed - Operations now modify Evaluation struct directly
• Evaluation is now a struct - Previously a class

Migration

Most users importing fluent.asserts or fluentasserts.core.base need no changes. See the Upgrading Guide for details.
