Version 7 focuses on making RegExpress more generous, more visual, and faster to use. The free tier now lets you save up to 20 patterns, keep 50 history items, use folders and search, and start with 3 tutorial modules. RegExpress Pro now has a lower one-time price of $4.99. Several Pro tools can also be tried before upgrading, including the visual debugger, pattern optimizer, pattern constructor, visual diagrams, pattern recommendations, pattern comparison, test suites, and code generation. New visual regex diagrams turn patterns into zoomable railroad-style diagrams, with warnings and token details to help you understand complex expressions. Quick Actions are now configurable. Choose which shortcuts appear in the main toolbar, including Library, Tools, Reference, Options, Keyboard, Playground, AI Assistant, Optimize, Debug, Builder, Test Suite, Save, History, Compare, Settings, Clear, and Code. Workspace test suite generation can create test cases from the current editor, connect them to a pattern, and open the generated suite for regression testing. Theme support has been expanded with a dedicated theme picker and app-wide color updates, plus refreshed light, dark, and tinted app icons. Simplified Chinese has been added alongside English, Spanish, and Brazilian Portuguese. Help tips, sheet headers, results filtering, search and replace, reference screens, pattern comparison, optimization, and tutorial/reference areas have been refreshed for clearer guidance and more consistent controls. This update also includes reliability fixes for drafts, iCloud sync, pattern history, imports, export formatting, accessibility identifiers, UI tests, performance tools, and several regex engines.

Version 8 is a major upgrade built around safer execution, flavor accuracy, and a faster professional workflow. Meet the new Focus Editor, a multiline workspace with a persistent token dock, flavor-aware options, railroad diagrams, code snippets, and direct access to building and testing tools. Run expressions with five distinct engines: Swift Regex, Foundation (ICU), JavaScript/ECMAScript, Python Compatibility Mode, and native PCRE2. Options, examples, the cheat sheet, Pattern Builder, optimizer, comparisons, and diagrams now adapt to the selected flavor. Execution is more responsive and reliable, with automatic or manual runs, cancellation, clearer errors, match limits, and improved protection from expensive backtracking. Save complete .regexpress workspaces, reopen .regproj test projects, and keep patterns, options, text, replacements, tests, notes, and metadata together. Structured local storage and sync improvements make saved work more dependable. Test suites now include richer results, edge-case intelligence, performance limits, progress, cancellation, and pattern health details. Pattern comparison now includes flavor-aware match, compatibility, and performance differences. Generate Regex has been redesigned around plain-language requirements, positive and negative examples, strictness, portability, expected captures, previews, and refinement. Recommendations, optimization, examples, and automatic library collections have also been improved. New productivity features include the command palette, Spotlight search, App Shortcuts, Share Extension support, deep links, incremental replacement previews, and improved workspace sharing. Version 8 also introduces a clearer free tier. Core regex creation and testing remain free, with useful allowances for saved patterns, history, test cases, Generate Regex, and previews of advanced tools. RegExpress Pro remains a one-time purchase with no subscription. This release also includes redesigned Examples, keyboard and scrolling fixes, accessibility improvements, localization updates, and many reliability refinements throughout the app.
