The BNRD interactive map has been updated to reflect this reroute, but the static PDF map (which has not been updated) shows that the routing was originally expected to be mostly unchanged, except that the route would be revised to (somewhat controversially, IIRC) bypass Sullivan to go directly to Assembly. The update to the interactive map shows that they now plan to maintain service at Sullivan (probably because getting from Washington Street to Assembly requires going right past Sullivan anyway.)
As noted in an aside by Teban54 above, this reroute means that all of Cross Street will lose bus service once the BNRD is fully implemented. The portion between McGrath Highway and Pearl Street will still be served by the 80 for the time being, but the portion of the 80 east of Powderhouse Circle is slated for elimination under the BNRD as it essentially duplicates the GLX. However, most people who currently use the buses on Cross Street will likely be able to use buses on Broadway (89 and 101) or Washington Street (rerouted 90 and 109*) instead. Under the BNRD, the 101 is slated to become a frequent route and the 109 has already been made a frequent route in Phase 1.
*The 91 and CT2 also currently serve this segment of Washington Street, but those routes are also slated for elimination under the BNRD.
Here are some minor changes based on what I remember from the Summer 2024 version. Unfortunately, the 2024 version was not archived. (An archive of the original Revised Bus Network Map in 2022 is here; only minor changes were made in 2024 and 2025.)
Route 85
Recall that BNRD's Route 85 is essentially today's Route CT2 south of Ruggles, but with an entirely new alignment between Union Sq (Somerville) and Assembly. This section was changed in 2025:
Amended to McGrath Hwy, skipping Cross St; likely for the same reason as Route 90 above
No longer makes a loop in Assembly Row via the Orange Line station, instead using Grand Union Blvd in both directions
This means the 85 no longer connects to OL
In the Union Square area, southbound 85 (to Ruggles) uses Somerville Ave and Webster Ave again (as per today's CT2), instead of straight through Prospect St in both directions (as per BNRD 2024)
Unclear if this was due to community feedback
The Somerville Ave @ Western Ave stop is closer to most destinations in Union Square and transfers to more buses
However, transfer with GLX Union Square becomes less convenient
Northbound 85 (to Assembly) still use Prospect St northbound, stopping directly at GLX Union Square station
Also note that the 47 remains unchanged and uses Prospect St in both directions, even though its predecessor, the 91, uses Somerville Ave southbound
(Note: Don't take the lack of stops on McGrath Hwy at face value. New stops on roads that do not currently have MBTA buses have not been finalized as of the current maps.)

Route 90
As @alewife mentioned above, the 2025 BNRD map basically makes the 90's route in the East Somerville-Assembly area identical to the Summer 2025 changes via Washington St.
Previously, the 2022 BNRD map suggested two changes to Route 90 below. Neither appear in the 2025 map, which now uses Washington St instead of Cross St and Broadway.
The 2022 proposal called for Route 90 to skip Sullivan Square, heading directly between Broadway and Assembly.
The 2022 proposal also called for Route 90 to make a loop in Assembly Row via the Orange Line station, just like the 85.
This means the 90 also no longer connects to OL Assembly, but it retains the OL connection at Sullivan (which is more popular)
Note: Route 113, the last of the three Assembly routes, has not yet been changed on the Summer 2025 map, and still makes the loop via Assembly OL. As the 113 comes from Chelsea and Everett, it also serves Sullivan. I think the 113's Assembly loop is also unlikely to last, but for the moment, there's no official evidence of this.

Routes 66 and 86
Originally, in the 2022 Revised Network Map, the 66 and 86 were planned to make the loop around (and layover at) Waterhouse St north of Harvard Square, similar to what the 71 and the 73 did when they used trolleybuses until 2022.
This change no longer appears in the 2025 BNRD map. Now, it calls for the 66 and the 86 to maintain the status quo:
Northbound buses terminate at Harvard Upper Busway, then makes a non-revenue turn to Dawes Island and layover there.
Southbound buses pick up at Dawes Island as the first stop.
It's unclear why the Waterhouse St loop was suggested in the first place. Unlike the 71 and the 73, the 2022 map didn't even have the 66 and the 86 use the lower busway for boarding; it also didn't have the 66 use the upper busway for alignting. If it did, we could have suspected that they wanted the 66 and the 86 to use left-door buses, but now that's moot.
Perhaps they were initially concerned about Dawes Island's ability for 2 routes to layover? Now that the 86 has been truncated for half a year, they may have decided that it's no longer an issue.

Based on my observations, the 66 and 86 currently loop around Cambridge Common via Waterhouse Street to lay over after alighting in the upper busway, as the 71 and 73 did in the trackless trolley era (and are planned to when left-door-equipped BEBs enter service at North Cambridge).
However, unlike the 71 and 73, those routes do not serve any of the stops on the loop (Garden St/Mason St and Waterhouse St/Mass Ave), which is likely why it doesn't appear on the map.

The Waterhouse and former Dawes Island layovers also have space on Mass Ave south of Waterhouse now: these parking spaces: https://maps.app.goo.gl/Yjgax8HRhADaYWgd7
They're trying to address bus layover in active stops because a bus laying over at Dawes Island for example blocks accessible boarding for other routes.
