SWF size history in Adobe Flash Professional CS5

You can now keep track of the size of your SWF in the Properties panel using SWF History. Every time you publish a SWF you'll see a running log of your publish size, date, and time. Three data points are displayed in the Properties panel but if you click the Log button you can see up to 100. You'll also see an alert icon if your SWF increased in size by more than 50%.
