Is 26.2 supported by Mineflayer? My bot is unable to join the server since it upgraded to 26.2.

No, not yet. That's what this PR is for, to work on updating MineFlayer to support 26.2

Sharing a set of live-tested 26.2 (protocol 776) fixes from running a Mineflayer bot against Spigot 26.2:

PRs

Repo	PR	Notes
minecraft-data (pc_26_2)	PrismarineJS/minecraft-data#1216	Login success sessionId UUID + play login onlineMode before enforcesSecureChat — removes partial-packet reads on every join (verified against NMS ClientboundLoginFinishedPacket / ClientboundLoginPacket)

mineflayer (pc26_2)	#3958	attack packet + 26.x use_entity shape + clockUpdates time + player_loaded on spawn

Live verification (Spigot 26.2 / protocol 776)

• Login/spawn without Chunk size is … but only … was read on success / login
• Look, walk, jump, pathfinder GoalNear, inventory, entity tracking, swingArm
• Chat receive + send (with enforce-secure-profile=false / RCON tellraw as app-level fallback when needed)
• Full smoke: 20/20 body tests passed

Happy to adjust any of these to match preferred style for the pc26_2 / pc_26_2 branches.
