Pack update time, here's a summary of the changes according to Claude.. let me know how useful that actually is, and I may include them going forward.

New content: Create Big Cannons, Shield Generators, and Animus added in 1.6.0; Mystical Automation, Linear Bearings, and Mystian Apiary added in 1.6.1. Twemoji was swapped out for Emojiful in 1.4.0.
Major reworks: Structure Placers replaced Redprint (1.3.0); the Advanced Coke Oven got a new multiblock structure (1.3.0); Platinum processing was reworked to align with Modern Industrialization's Oritech tree (1.6.0).
Notable fixes: a duplication exploit via ship-assembly (sifters, item drains/vaults/sluices duplicating contents) fixed in 1.5.1; a disconnect-on-world-load crash and airship physics crash-tracking fixed in 1.6.1; two day-one hotfixes shipped (1.4.1 for a missing server dependency, 1.5.1 for an AppliedFlux crash).
Dozens of smaller duplicate-recipe and quest-text fixes throughout, omitted here as routine.

The next server will be running FTB Skies 2: Aero, a skyblock built around flight. Everyone spawns into a shared lobby, picks a starting island (or an airship if you want to fly off day one), and the whole overworld is a scattered archipelago you cross by ship rather than by hopping between private voids. It keeps the tech/magic/automation depth from the first Skies pack, but this time you can actually fly over and visit other players.

You can download the pack from any FTB or Curseforge compatible launcher

The server will open Friday, July 31st, around 5pm UTC (click here for your timezone)

Server Address: aero.stonebound.net
Additionally if you are on the west coast of the US and have connection problems with the main one, there's also a new alternative address aero.la.stonebound.net

Not your kind of pack? Make sure to nominate packs for the March vote in the #modpack-suggestions Discord channel.

Tomorrow we're starting a playtest of our upcoming modpack. A play-what? Yes, a playtest. It will last until Monday, June 29th. But why? This modpack is a bit more special than other packs hosted on Stonebound. It is custom made for the community by @dedmaxim99 and has the goal of surviving Minecraft version changes without resetting the map. So we want to make sure everything is perfect and everyone is satisfied before we go into full launch. During and after the playtest, we're asking you to provide feedback about your experience, what you like about the pack and what you don't, what mods you want to see included and which you want to see removed. Additionally, there are some mechanics specific to this modpack - you can learn more about them in the quest book.

You can download the pack "Stonebound Eternal" from any CurseForge compatible launcher.
The playtest server will open Friday, June 19th, around 5pm UTC (click here for your timezone)

Server address: eternal.stonebound.net

We look forward to your feedback!

Most noticeably, no need to update the season file anymore as it should sync automatically, hopefully
also lots of trainer podium rebalance
