Update on this: Andy informed me the beta 2 release was not feasible to reach for 32-bit support, it will be for beta 3.
Will it require another subversion of NC25 to have the NC26 blocker removed, or is the blocker in NC26 or update server code only?

the blocker in NC26 or update server code only?
The new beta3 of nc26 claims compatibility with 32-bit. Have not seen any 25.x release which reintroduces support (yet).
Can anyone confirm if any upcoming 25.x release that will include 32-bit support, which was originally assumed for the 25.0.2 point release in announcements?
I mean the blocker for updates from NC25 to NC26 on 32-bit systems can theoretically be within the NC25 updater code, somehow placed on the update server, or within the NC26 code. If it was within the NC25 updater code, another NC25 update would be required to unblock updates to NC26 on 32-bit systems.

Can anyone confirm if any upcoming 25.x release that will include 32-bit support, which was originally assumed for the 25.0.2 point release in announcements?
NC25.0.2 has 32-bit support. The only left issue I am aware of compared to NC24 is that user quota does not work.
I think it needs 25.0.4: [stable25] Revert #34908 to allow 32bit setups to upgrade to 26 by backportbot-nextcloud[bot] Β· Pull Request #36593 Β· nextcloud/server Β· GitHub
What SysKeeper wrote, the next release of 25 (25.0.4) due to this week Thursday 16th Feb. 2023 will remove the 32-bit upgrade blocker so you will then be able to upgrade to the v26 beta versions, later RCs and stable releases.
Hello everyone
Lately I start to consider setting up my own Nextcloud server and hesitated when I see that 64-bit is a requirement in the nextcloud documentation, so I used KVM to setup a few nextcloud servers on 32-bit and 64-bit processors, and tested on my own. So far 32-bit servers seems to be running well for my workloads (I didnβt reached the 2GB/3GB limitations since Iβm only storing some work documents and private notes on it), so I began to get my hands dirty setting up nextcloud server on my physical device (RasPi 2 with 1GB RAM, now you see why I do these tests ) with the experience I learned from virtual machines. Itβs good to see that 32-bit hardware is still supported
The VMs I set up has the following configuration:
- 2G RAM 20G VirtIO Disk + Debian bullseye i686 + Apache2 2.4.54 + PHP 7.4 + MariaDB 10.5.18 + Redis 6.0.16
- 2G RAM 20G VirtIO Disk + Debian bullseye amd64 + Apache2 2.4.54 + PHP 7.4 + MariaDB 10.5.18 + Redis 6.0.16
- 2G RAM 8G VirtIO Disk + Alpine Linux i686 + Apache2 2.4.55 + PHP 8.1 + MariaDB 10.6.12 + Redis 7.0.8
- 2G RAM 8G VirtIO Disk + Alpine Linux amd64 + Apache2 2.4.55 + PHP 8.1 + MariaDB 10.6.12 + Redis 7.0.8
