We’ve made over 400 tweaks since releasing Lightroom 5 beta, many of which are directly attributed to your feedback in our public forums. Thank you.
Lightroom 5 is now feature complete and final. Lightroom 5 will be available for $149 (for those new to Lightroom) and $79 (for Upgrade and Student/Teacher editions). As with previous version of Lightroom, Lightroom 5 is a perpetual license.
