From the DSDPlus.txt file:
DSD+ Fast Lane
Early access to features is being offered through the DSD+ Fast Lane program.
Fast Lane updates are expected to be released about once per month.
Some Fast Lane updates WILL have issues/bugs. That is the nature of alpha software.
Fully tested public releases will continue to be released, approximately every 6 months.
In light of the extra workload the Fast Lane program will create, the DSD+ team is asking Fast Laners for:
US$10 for one year of Fast Lane updates
US$25 for unlimited Fast Lane updates
Donations above these amounts are welcomed, but it's up to you. We're not looking to get rich here. Funds will be used for things like needed hardware upgrades.
Funds can be sent our Paypal account (email@example.com)
Please include a comment that specifies the email address that your Fast Lane updates should be sent to.
NOTE: IF YOU DO NOT INCLUDE A COMMENT, PAYPAL DOES NOT SEND US A NOTIFICATION. THIS *WILL* DELAY YOUR FIRST FAST LANE UPDATE.
The Public version of the software and updates to the software can be found at the DSDPlus website
The creator asks that any bugs be reported on the Voice Control Channel Decoding Software Forum
