Bots4Velo v3.0.9

Bots4Velo v3.0.9

This release adds Minecraft 26.3 (protocol 777) support.

Changes

• Add a modern-26_3 transport adapter built on MCProtocolLib 26.3.
  protocol-version: "26.3" and AUTO detection of protocol 777 now select it.
• 26.3 replaced the serverbound swing packet with a hand-less punch packet
  and extended teleport acknowledgements with the resolved position. These
  packets now come from a per-version compatibility class, so the 1.21.11,
  26.1.2 and 26.2 adapters send exactly what they sent before.
• On 26.3 the bot follows every position packet (teleport acknowledgement or
  movement) with a client tick end. 26.3 servers kick clients that send two
  position packets in one client tick with "Invalid move player packet
  received".
• Relocate MCProtocolLib's NBT text serializer (org.geysermc.adventure)
  inside each modern adapter. It was previously unrelocated, so only one
  copy survived in the merged plugin JAR.

Requirements

Bots connect through the Velocity proxy itself, so 26.3 bots need a Velocity
build that supports 26.3. Velocity 3.x stops at 26.2 and rejects 26.3 clients
with outdated_client; Velocity 4.x supports 26.3 and requires Java 25.

Verification

CI covers 1.16.5, 1.21.11, 26.1.2, 26.2 and 26.3 protocol contracts and runs
the disposable network integration for each. 26.3 is tested against Paper
26.3 beta builds on Velocity 4.2.1-SNAPSHOT, because Paper has not published a
stable 26.3 build yet.
