 ## [Unreleased]
 
+## [2.1.2] - 2025-07-30
+
+### Fixed
+
+- Preserve trailing delimiters instead of moving to beginning. This resolves an issue where trailing delimiters (like commas at the end of lists) were incorrectly repositioned to the start of sorted content.
+
+### Added
+
+- Enhanced release script with automation support. The release script now supports CI environments, dry-run mode, and improved validation for streamlined releases.
+
+### Changed
+
+- Enhanced error handling and validation across core modules for improved stability.
+- Updated test infrastructure to use minimal_init.lua for better test isolation and reliability.

 ## [2.1.1] - 2025-07-12
 
 ### Fixed
+
 - Corrected natural sorting priority for punctuation characters. Shell aliases like `@l` now properly sort before text identifiers like `A` when using natural sorting. This resolves an inconsistency where punctuation-prefixed identifiers were appearing after text identifiers instead of before them.
 
 ## [2.1.0] - 2025-07-11
 
 ### Added
+
 - Enhanced natural sorting with punctuation priority. Identifiers with punctuation (like `A=`, `func()`) now sort before identifiers with numeric suffixes (like `A1`, `func2`) when using natural sorting (`z` flag). This makes sorting more intuitive for shell aliases, CSS selectors, function definitions, and other programming content. Resolves #11.
 
 ## [2.0.1] - 2025-07-10
 
 ### Fixed
+
 - Multi-line character motions with text objects (e.g., `goi{`) now preserve whitespace correctly by treating "perfect lines" selections as line motions (#10).
