In mid-May we informed Manjaro users of bad news, or half bad: We commented it as they were going to make "an Ubuntu", in the sense that they would stay for a while with the GNOME 3.38 Shell and GNOME 40 apps. At the time we said it would be less time, but that the developer team had to find out how to fix some things. They have already done it and they just announced which will reach the stable version with the release of manjaro 21.1.
The codename they will use for this series will be Pahvo. During the weekend they already advanced that there would be news soon, but they did not provide much information. On twitter Yes we could see something: in the Layouts app, which is where the desktop layout is chosen, the default option happens to have the dock at the bottom, or more specifically that will be the one that bears the name of the operating system. That is, the 6 options in Layouts will remain, but the current Manjaro will be renamed Manjaro Legacy, and the one that will receive the name of the operating system will be the one that until now was called Modern.
The Manjaro Shell will go up to GNOME 40 soon
They spent some time testing, and now you can download an ISO with GNOME 40 from this link, specifically an Unstable for developers. If nothing happens and the deadlines are met, users of this popular Arch Linux-based distribution will be able to use the new Shell in about two weeks, so the "Ubuntu" that will be marked will be about two months.
As for the GNOME 40 gestures, the Manjaro developers have been working to find the best solutions and we don't know what that will translate into. The default layout probably looks a bit like GNOME 40 as it is, but there is sure to be a change. On the other hand, we were assured that we would have full control, and this could simply mean that we can use GNOME 40 100% if we choose the GNOME layout.
Updated: From what I have been able to verify in the developer image, the project proposal is almost exact to the one offered by GNOME, with the only difference that the dock is visible at all times. By sliding three fingers up you enter the activities and the app grid, and by sliding to the side you change the virtual desktop.
