Is there one supposed to be coming? The last game update was on June 23rd, in July there only was one on the 4th for Manchester Airport Commuter.
On June's roadmap stream Alex talked a lot about a large set of updates coming early July, we then had a large set of updates on 23rd June so I'm inclined to think it came early rather than never happened.
If you read the article it states the next major core update will be rolled out for TSW6. Below is what it states on the roadmap The next major improvements towards performance will come alongside the release of Train Sim World 6 and beyond, which you will be able to access at no additional cost via the Free Starter Pack, and our teams are looking at addressing blurry textures and visual quality as a key focus, now that core stability has improved. Thank you for your patience as always everyone, we look forward to continuing to make Train Sim World the best experience possible with further improvements.
I think OP may be talking about the "additional improvements" in the 0-3 months category, which suggests a small update is due. But major optimisations have been moved to tsw6
They mention what they mean by that in the article as well, but nowhere does it say a July release. You should never go by just the graphic and actually read the articles they do provide most information people are looking for. Alongside our upcoming releases to Train Sim World 5, our teams will be continuing to look at opportunites to include improvements and fixes for community-reported issues with these updates. Our next update will include some key fixes from the TSG team for the BR 194 / E94 Railtour Pack, detailed below: Fixed an issue with Livery designer on BR 194 and Umbauwagen Fixed an issue that prevented snow from showing properly on Umbauwagen Fixed an issue with the wiper and blind animations on the E94 088 cab Fixed an issue with the weather glass effects on the E94 088 Fixed an issue with excessive brake hisses in the E94 088 Cab
