HI @RadekCap
if this gets approved for 24u, we want to get this into the July update.
Thus, in this case, we will need a PR agains jdk21u, not jdk21u-dev.
But we need to wait on the decision for 24u.
I remove the approval tag in the meantime. Please label again if it get's denied for 24u (or does not make the July update).
If it makes the July update of 24u, please open a PR agains jdk21u and label jdk21u-critical-request.

[RadekCap]

Hi @GoeLin,

Yes, I'm waiting for 24u approval. Let's see which will come sooner: the July update or 24u approval.
If approved first, I'll create a PR against 24u and close this one. The same situation will likely apply to 17 (PR already exists and waiting for 24u, 21u approval), and later to 11.

If it makes the July update of 24u, please open a PR agains jdk21u and label jdk21u-critical-request.

I don't see anything going into 24u at this juncture. I can't see a closure message on the jdk-updates-dev mailing list, but apparently it entered RDP 2 as long ago as April 22nd, right after the last release. July's release will be the last update for 24u, before 25 is released in September.

If we do want to get this into July ourselves, we should do so ASAP as the freeze is imminent (a week today for 17u & 21u, the Friday for 11u)

Generally, I would say give the latest release two weeks and proceed with the LTS releases if nothing is approved in that time frame.

/approval request Update IANA Language Subtag Registry to Version 2025-05-15

Approval requests should really explain why this should be backported to the update, the expected risk and testing that has been done, so that the approver can make an informed decision.

[RadekCap]

Updating the approval request to make the review easier.
