For Julia 1.12 and later, PowerPC will be demoted to Tier 4, and release binaries will not be available for download.
Julia 1.10.x and 1.11.x will continue to have support for PowerPC on Linux at the existing support tier (Tier 3).
Hello
Any chance to revert this decision?
We trust in PowerPC parallel features but also it’s important to guarantee compatibility.
What are major constraints?
Regards
Only if someone volunteers to fix all the bugs related to this platform.
Lack of manpower to fix powerpc-specific bugs.

It’s worth noting that the tiers are really descriptions of the status quo. If the status quo changes, the tier can change.
- Tier 1: Julia is guaranteed to build from source and pass all tests on these platforms when built with the default options. Official binaries are always available and CI is run on every commit to ensure support is actively maintained.
- Tier 2: Julia is guaranteed to build from source using the default build options, but may or may not pass all tests. Official binaries are available on a case-by-case basis.
- Tier 3: Julia may or may not build. If it does, it is unlikely to pass tests. Binaries may be available in some cases. When they are, they should be considered experimental. Ongoing support is dependent on community efforts.
- Tier 4: Julia built at some point in the past, but is known not to build currently.

In other words PowerPC is tier 4 not because we’ve decided anything but because it doesn’t build anymore and no one with access to PowerPC has fixed it. If you have PowerPC hardware you can fix it. We don’t have PowerPC CI or even machines to develop or test on, so this is not really in our power to fix.

I see your point.
Probably RISC instructions could be the real issue.
It’s quite strange that IBM is not interested to make available HW for the community that it sponsored so much.
Commercial and marketing strategy very poor
A great occasion lost for many customers that love multi core capabilities 
Thanks
