1.18 Structures Advisory + b1.6.4 ETA Announcement (1.17.x + 1.18.x)

1.18 Structures Advisory + b1.6.4 ETA Announcement (1.17.x + 1.18.x) Apologies for the secondary ping @everyone but due to the existence of mojang bug 241288 (https://bugs.mojang.com/browse/MC-241288), 1.18.x Custom Structures may not be currently doable (IE structures will not be able to generate in the 1.18 port). A silver lining of this however, is that the majority of the team has come to a unified decision: We currently intend, provided all goes well, to release the 1.17 AND 1.18 versions of b1.6.4 on or before February 14th 2022 This current eta allows the team at least 1-2 weeks of diagnosing any remaining port issues + giving a hearty few more attempts at getting structures working + implement some final tweaks we have in mind for world generation. Any changes made between now and then are also still subject to be backported to the 1.17 branch as well! 😄 (if it is stable to do so and does not involve worldgen, given mojangs changes) We appreciate all your patience as we begin to finalize and wrap up b1.6.4s development! Additional Notes:

After b1.6.4, we expect to likely need to push a few more versions for any outstanding bug fixes or parity adjustments,
before moving onto the b1.7 pipeline.
The 1.17.x branch will remain supported at this time until the release of b1.7, with backports coming from the 1.18 branch as needed.

If we are unable to make 1.18 custom structures work due to the aforementioned Jira issue, we will state as such in the changelog in an effort to avoid any misinformation and confusion relating to the absence of them.

Thanks to everyone once again, and stay tuned for more updates! 😄(edited)
