Anybody know if there will be new ios xe 17.15 for isr4331/4431/4451-x? Or 17.12 will be last?
Now we have new software only for 4461 (17.13/17.14)

17.15.1 will be coming out in 6 weeks (barring anything bad discovered).

But I wondering about isr4331, because now it has only 17.12 version, while for isr1000 and isr4461-x have 17.13 and 17.14. Maybe 17.12 will be last version for isr4331

Software support for the 4300 is not until 31 August 2025.

you mean just until 31 August 2025. So it's pity

No, it means last software support is 31 August 2025. This means there should be more software releases between now and 31 ugust 2025.
One important thing I want to mention is: It is not possible to do a firmware upgrade from 17.3.X to 17.12 without jumping to an intermediate version like 17.9.X. The reason for this undocumented fact is because 17.12.X requires a ROMMON version of 17.5.1r and the auto ROMMON upgrade only happens in 17.9.X. Auto-ROMMON upgrade is not supported on 17.10.X and later.
The above information is undocumented: I have trawled through different Release Notes for the 1000, 4000 and 8500. All I can see is a matrix table about firmware version and recommended ROMMON version. Nowhere in the Release Notes mention anything an "intermediate" version like 17.9.X.
Cisco introduced the auto ROMMON upgrade after several big customers were not aware that certain versions require certain ROMMON versions. Customers were not (made) aware because Cisco did not include this vital information in the Release Notes. It was "hidden" in plain sight: It was present in some platform but not the others.

Yeah I saw EOS for 4200/4300/4400 but for ISR4461-X we have software 17.13/17.14 but for 4200/4300/4400 hasn't so I thought that it ended.
By the way, the last software support falls on August 31, 2025 - this may mean that the software will be finalized for 17.12

found this picture for isr4000, so I think for isr4331 we will have only version 17.12
Note: Last supported IOS-XE Release trains will be the 17.9.x and 17.12.x for the listed ISR 4000 Platforms. IOS-XE Release trains 17.10.x and 17.11.x will not be supported. For SD-WAN deployments, future vManage Releases 20.12, 21.3 and 21.6 will support IOS-XE Release train 17.12.x

In that case, 17.12.X is the last-and-final release train for the 4300 and 4431/4451. (4461 can support 17.14.X so I am going to assume this will get extended to 17.15.X.)
Note: Last supported IOS-XE Release trains will be the 17.9.x and 17.12.x for the listed ISR 4000 Platforms. IOS-XE Release trains 17.10.x and 17.11.x will not be supported. For SD-WAN deployments, future vManage Releases 20.12, 21.3 and 21.6 will support IOS-XE Release train 17.12.x
