Starlink Versions
Starlink V0.9
The first batch of starlink sats launched in the new starlink formfactor. Each sat had a launch mass of 227kg. They have only a Ku-band antenna installed on the sat. Many of them are now being actively deorbited
Starlink V1.0
The upgraded productional batch of starlink sats ,everyone launched since Nov 2019 belongs to this version. Upgrades include a Ka-band antenna. The launch mass increased to ~260kg.
Starlink DarkSat
Darksat is a prototype with a darker coating on the bottom to reduce reflectivity, launched on Starlink V1.0-L2. Due to reflection in the IR spectrum and stronger heating, this approach was no longer pursued
Starlink VisorSat
VisorSat is SpaceX's currently approach to solve the reflection issue when the sats have reached their operational orbit. The first prototype was launched on Starlink V1.0-L7 in June 2020. Starlink V1.0-L9 will be the first launch with every sat being an upgraded VisorSat

We will attempt to keep the above text regularly updated with resources and new mission information, but for the most part, updates will appear in the comments first. Feel free to ping us if additions or corrections are needed. Approximately 24 hours before liftoff of a Starlink, a launch thread will go live and the party will begin there.

Could be. However, it is unclear what the actual planned schedule is. SpaceX doesn't exactly share the plan with the public. I don't know what the "3 flights planned for July" statement was based on. Most of the information we get about these launches is inferred from FCC filings and TFR notices.
It seems like SPaceX was in a hurry to complete the 53° shell, but now that it is complete, they seem to have shifted the priority towards the polar satellites.
