Rivencraft 26.3.0.3

For Minecraft 26.3, NeoForge 26.3.0.99 and Java 25.

Book preview exploration

• The eye button now matches 1.21.1: it grabs the mouse for look-only exploration while the destination view remains inside the book panel. Movement is disabled.
• Right-click returns to the ordinary book controls without releasing the preview. Books on stands retain their disabled exploration button.
• Fixed the exit crash caused by a forced render and duplicate Reborn render-target submission. Pending target submissions are reused until the renderer drains them.
• Removed remaining Beta branding from the in-game mod name/description.

Port acceptance and maintenance

• Completed dedicated-server restart/return-link acceptance for #100, following the two-client matrix and its manual handoff. The player confirmed return travel.
• Added changed-target build/smoke workflows, sequential test-server exclusion and repeatable dual-version validation commands.
• Hardened release uploads against mismatched filename, embedded version, Minecraft/Java target and accidental test-fixture packaging. The 1.21.1 metadata declares its required Dynamic Dimensions AR and Bad Packets dependencies.
• Documented the feature parity review and ongoing independent support of 1.21.1. Existing 1.21.1 code and published artifacts are unchanged.

Validation and known issues

The player passed the live-view exploration/right-click/re-entry check and the dedicated-server Age restart/Linking Book return check. The expanded-catalog two-client matrix passed creation/catalog/travel/stale-ack/lifecycle checks; its final return step stalled and was completed by the player, not retried. Release-tooling checks pass. No optional mod or test fixture is bundled.

Known issue #116: Static Sky can leak outside book previews with Reborn. It remains separately tracked. Other shared follow-ups remain open where needed. Create/Ponder is not ported to 26.3. Without Reborn, built-in animated previews and normal book/portal travel remain available. 1.21.1 saves are not imported.
