To celebrate the launch of Komodo 9, enjoy great savings on new licenses and upgrades through April 30th!

What's New

  • Track Changes

    The editor has gained a new left margin, which highlights unsaved changes, as well as any uncommitted SCC changes. Clicking on the margin shows a diff dialog of the changes, and allows you to revert individual changes. Sweet!

  • Commando (Go to Anything)

    This powerful popup dialog is the combined successor of the Fast Open and Invoke Tool dialogs in previous versions of Komodo. Commando provides fuzzy matching, match highlighting, search for files (find any file under a folder), toolbox search, bookmark integration, shortcuts (go-tool) integration as well as custom category filtering.

  • GoLang Support

    Google Go (GoLang) is now supported in Komodo, and features syntax coloring, code folding, syntax checking (linting) and code intelligence

  • Markdown Viewer

    For Markdown files, Komodo provides a preview of the generated HTML directly within a Komodo split view and contents dynamically update whenever you make a change to the Markdown text - it doesn't even need to be saved.

  • Helper

    Like pastebin, now you can easily share snippets of code with other people directly from Komodo. Simply make a text selection and use the editor: right-click context menu and choose Share Code via supports client side encryption, so you can make those shared pastes more secure.

  • Color Schemes and Themes

    We've updated the Komodo color schemes and we've made Tomorrow_Dark the new default Komodo color scheme (a dark-based scheme). The Komodo UI has been updated to match the latest operating systems, so Komodo now looks even better. We also added the ability to tweak the editor line height spacing.

  • Notifications

    Notification messages shown to the user now appear in a separate popup panel that overlays the main Komodo editor window (they previously appeared in the Komodo statusbar). This makes for a more intuitive and informative use of Komodo; no more asking yourself "What just happened?".

  • Language Icons

    Language icons have been overhauled to be consistent and easily identifiable by their colors and emblems. Komodo dynamically generates new icons for filetypes that it has not previously encountered, so you'll always have unique icons for each language.

  • New Developer SDK

    An overhaul of the Komodo APIs makes it easier to load and access the methods inside of Komodo. We're now making use of CommonJS (aka Node.js) require() calls to load individual modules.

  • Language Support
    • PHP Updates: We've added support for PHP 5.6, with a new Xdebug module (for PHP debugging and Code Profiling), updates for keyword changes and updates to code intelligence to provide the latest API data for PHP 5.6.
    • Python Updates: Python 3.4 is fully supported for syntax checking, debugging, code intelligence, etc… We've also added PEP 8 syntax checking - you can enable this in the Python Syntax Checking preferences.
  • And Lots More!
    • Changes to the file, language, places, toolbox, preference page and code intelligence icons
    • The menu bar (i.e. the File, Edit, etc.) is now hidden by default on Windows and Linux. Use Alt to toggle the menu visibility.
    • Tons of Performance Improvements
    • Preferences dialog improvements, simpler and easier to apply preferences
    • High DPI/Retina fixes/improvements
    • Komodo start page has been removed and replaced by a "Quick Launch" page
    • And much, much more
