Cal Poly wants feedback for their new spec at https://static1.squarespace.com/static/5418c831e4b0fa4ecac1bacd/t/5f24997b6d...

"The original CDS introduced the CubeSat Standard to the world almost two decades ago. It defined the physical and electrical characteristics for a 1U and 3U size CubeSat and included requirements for interfacing with the only CubeSat dispenser available at the time, the Poly-Pico Orbital Deployer (P-POD). Since then the industry has expanded to include more standard sizes and additional dispensers with more available options.

To accommodate these new advancements, the CDS has been retooled to be more flexible and inclusive of developments within the industry. Requirements that were originally written specifically for the P-POD will encompass requirements for all dispensers currently available. It is also the intention for the new revision of the CDS to identify the available options on dispensers that are widely available for use. Currently that list is limited to dispensers that publish their specifications online, but can be updated as dispenser companies make that information available to us. The CDS will also define all U configurations in one document with one set of requirements for ease of reference."
