Because I tend to release new versions of ecto quite often, I have decided to slow down the releases and, instead, resort to making intermediary builds available. This way, most users won't have to bother downloading versions that are only minor changes, while the more hardcore users can have as many updates as they want.
Latest builds are listed in the side bar of ecto's main page, under the "development" header.
Please do keep in mind that these intermediary builds may not be well-tested. If you find a problem with a latest build, please report it in the support forum.
