Zwift Update Version 1.66 (129838) Released

Zwift version 1.66 begins its phased rollout today. This is another light update, but watch for news next week on Watopia’s “The Grade” expansion releasing mid-June!

Ghost Powerup Changes

The cloaking (or “ghost” or “invisibility”) powerup makes you invisible to other riders for 15 seconds. It’s event-only, so you only see it in races where organizers have requested it to be enabled.

Several months back, Zwifters noted that Zwift had added a slight shadow beneath riders, and that shadow was visible even when the rider and their “real” shadow were hidden while using a ghost powerup. This slight shadow became affectionately known as “The Smudge”, and eagle-eyed Zwifters began using it to track ghosted riders:

The Smudge of a ghosted rider…

Additionally, it’s long been known that if you’re cheeky enough to wear Fire Socks in a race, the fire trail is visible even if your rider is hidden thanks to a ghost powerup. Back to the Future vibes, for sure!

Today’s update makes two changes to the ghost powerup. First, if you’re wearing Fire Socks, the fire trail is hidden while the powerup is active. Secondly, The Smudge is also hidden.

These two changes make it so riders using the powerup are indeed invisible.

More Release Notes

Zwift provided notes on additional tweaks and bug fixes in this update:

  • Fixed an issue that could cause the “Weekly Goal Met!” banner image to be blank.
  • Fixed an issue where the route progress bar could disappear on the Zwift Games Epic 2024 route.
  • Corrected the cadence target in one of the Spaded Sweetie workout blocks.
  • TrainingPeaks workouts now include the next seven days of workouts, which are available in the TrainingPeaks custom workouts folder.
  • Fixed an issue that could cause some BH Fitness treadmills to not send speed data.
  • Apple TV, iOS: Fixed an issue where some Apple TV or iOS users may have to re-enter their login credentials after a Zwift game update.

So mid-June is the new early June promised.

I had wondered if one of those was going to be the secret, special route for the summer ZRL, but there likely won’t be time for that to happen.

I suspect it will hit in time for that hopefully. Confirmed on forums it will be June

I suspect one of the new routes will be part of the June zRacing series. Only 3 stages have been loaded as events, 4 are needed to fill the month and they’ve always loaded them in one hit. Must be some reason stage 4 can’t exist yet.

Wait, there was a route progress bug on the Zwift Games Epic 2024 route?! I KNEW I didn’t make a turn and get off course…but when I was 50km in and it was gone (after a pace partner had been with me) I decided to do something else. Should have driven on…

I still think the drafting needs to be sorted out. Even riding at 2.3, C grade. You cannot ride at 2wpkg. If you aren’t having a great day, you end up out the back and need to push hard to get back on.. then you are suddenly at the front and it easier once again. If they want to make it real world, they need to fix this so that riders at the back are actually saving a lot more than 10%. In the real world you get dragged along.. why can’t they make it like that? I only ever feel like I’m saving watts, if I’m in a 2, 3 man line.

I can’t be the only one like this.. surely.. and don’t call me Sherly.

There’s one recent bug that is suuuuuuper annoying for users of the Climb Portal. When running on my Mac, I notice that my segment PR time data for each of the ten segments of any climb is positioned over the top of my current average power for that segment. As a training tool, the entire reason for using the Climb Portal on a long steady climb like Fuji, for example, is so that you can do over-under intervals and see, in real time, your average power for the interval you’re doing. Now if I want to see that clearly, I have to turn on my Garmin . . . while using Zwift. Here’s hoping that the upcoming refresh to the HUD also fixes the segment data sidebar for the climb portal.

But can you still draft off people when they’re using the ghost?

Hey Eric. Slightly off topic but I’m pretty sure the build number should be 129838 rather than 192838.

Ghost is still too short to make an effective breakaway attempt though, IMO.

You just gotta sprint off the back off someone in the last 1k or so and hold VO2 max to the line, just don’t get got!

I agree: longer ghosts would make for much more interesting and diversed racing…

I completed the bag that badge challenge but did not get the route badge for Queens Highway After Party. What is the problem?

Not sure if related to this update but …
Play controllers pair fine in pairing screen but gear shifting didn’t show or work in game. BUT the Y and Z keys work fine. Steering buttons even work.
Restarted game repeatedly and even restarted computer (Macbook pro). Tried pairing in game too.
Just did Stage 4: Bag that badge in what I assume was 12th out of 24 gear. Kind of refreshing; a 20k fixed gear RR.
Thoughts?

Thanks for all you do and for the response. I thought I always got the Bluetooth symbol but it’s a great place to start checking.

I have exactly the same problem. Was it the bluetooth that was the problem or is it still not working?

I think I was rushing the pairing process: if I wait until the pairing box turns blue the controllers usually control shifting. Still can’t get the click to pair and, yes, I put in a new battery.

I’ll just leave this here.. ‘In early May 2024, the 100-level system will be revised. We will share more specifics when this revised system is launched, but as a preview:’

They posted to the forums that they are revising the change they want to make it’s delayed.

If you take Tic Tok and then the Titans Grove exit there’s a big blotch of turf in the road at 18.1km (total distance). It’s been there for months.

I would very much like to see a possibility again to shrink ui elements on the home screen. It is now difficult to search for the right one(s).

Has the probability for 250XP in climb portal been changed? I just have the impression that I have to ride much longer to earn 250XP.

I am on release 1.66. Since loading it yesterday (I haven’t used Zswift for a month) the Resistance Bluetooth connection drops after 30 secs or so. The Other Bluetooth connections are all fine. This makes Zswift unusable obviously. I am using the Android version. I have also checked the Zswift firmware is up to date. Has anyone else experienced this problem?

Apple TV, iOS: Fixed an issue where some Apple TV or iOS users may have to re-enter their login credentials after a Zwift game update. This still has not been fixed. I need to log in everytime
