if you already have velocity installed you can just go ahead and close out the UI and reopen and the update will be applied.
Updated:
[!] Our old website 'getvelocity.lol' was taken down by cloudflare and our old APIs no longer work, if you have issues with the auto updater not working etc you'll need to grab the new file from our website or dc server or you can redownload velocity entirely from the site
[!] Rewrote isparallel / checkparallel / inparallel
[!] Fixed isscriptable
[!] Fixed setscriptable
[!] Fixed gethiddenproperty
[!] Fixed sethiddenproperty
[!] Bypassed detection on getscriptclosure causing users to get banned on Roblox if used #UDFromTheCheck
[+] Added filtergc
[!] Fixed auto-execute (will only load .txt & .lua files)
[!] isscriptable & setscriptable & filtergc now pass on sunc test, 96% sunc (technically 98% but sunc gethidden and sethidden tests are broke)

Please only use Velocity IDE on your alt account, Roblox's new update detects any form of client modification (they could patch the bypass at anytime)
Version is now 0.6.8
Injector version: 0.6.8
also if you're using bloxstrap or fishstrap please make sure you're using DirectX 11 else velocity will just crash instantly and make sure you're on the correct version of Roblox which you can find by doing ?velocity in bot-commands
