[1] Cached teleports are basically instant now. The cache keeps the chunks of the next few spots per world loaded (location_cache.warm_chunks, default 3 per world), so a cache hit no longer waits on a disk read. Went from around 47ms to 0.1ms in testing. The next spot also keeps a small 3x3 ring warm (head_radius), the whole thing runs off the main thread, and it scales down to almost nothing when the server is empty. If you want to verify it yourself: /rtp benchmark cache. There is also an optional serve_trust_seconds to skip the safety recheck for freshly validated spots (off by default).

[2] The location search now runs DURING the teleport delay instead of after it. With delay 3 and a search that needs 2 seconds you used to wait 5, now you wait 3. Cancelled warmups put the found spot back into the cache. performance.prefetch_during_delay, on by default. config-version 46.

[3] Blocks load much faster when you land in fresh terrain. The plugin now pre-generates the area around the next cached spots in the background (warm_chunks.pregen_radius, default 3), so on arrival the chunks stream from disk instead of being generated live while you stare into fog. Skips already-generated terrain, pauses on low TPS. config-version 47.

[4] The search stopped wasting chunks. If the picked spot in a freshly generated chunk is unsafe (ocean, lava), it now checks up to 12 other spots in the same chunk before generating a new one (location_cache.chunk_scan_columns, 0 = old behavior). Cold searches dropped from ~1300ms to ~500-600ms.

[5] The search also remembers where it failed. Bad chunks and clusters of them are avoided for 15 minutes (location_cache.failed_area_memory), the dice are just rolled again, so the landing spread stays exactly as configured. Worst-case searches over ocean-heavy areas went from 5.4s down to about 2s and keep improving while the server runs. Cleared on reload. config-version 49.

[6] New optional smooth_transition.chunk_focus: narrows the player's send view distance for a few seconds after arrival so the terrain around them pops in sooner, then restores it. Off by default, test it with your view distance first.

[7] /rtp no longer sends you to the spot you are already standing on, or to one of your last six destinations. Those spots stay available for other players. And if literally every cached spot is one you recently visited (happens when you spam /rtp), you get the oldest one instead of waiting seconds for a fresh search.

[8] Powder snow no longer counts as safe ground, players used to sink in and freeze. The slow falling from smooth_transition now ends the moment you touch the ground, so jumping right after a teleport no longer feels floaty (air drops keep their parachute). Quiet servers also keep at least 8 learned spots per world cached.

[9] All five GUIs (dashboard, performance panel, world selection, zone browser, party) moved onto the shared JustAPI menu framework. Same layouts, same config keys, same behavior, about 700 lines less duplicated GUI code, and every menu gets the full anti-dupe protection (shift-clicks, hotbar swaps, drags, double-click collects). Zones and Performance opened from the dashboard now switch in place and their bottom button becomes Back. Sounds were compared menu by menu against the old versions: nothing doubled, nothing missing.

[10] The dashboard builds its items about 10x cheaper: one item-meta pass instead of three, and text is parsed once per config load instead of on every open. Looks and behaves exactly the same.
