## [0.7.3-alpha] - 2026-09-03 ### Added - **Chunkforce auto mode, default off.** Engages forced generation when a player sustains ~40 blocks/s; `/ferrite chunkforce auto on`. Off by default: a 10-run interleaved bench at 90 blocks/s measured 8.1 missing chunks against vanilla's 0.9, worse in every pair. - **`/ferrite arrival` monitor, `/ferrite arrival bench` and `/ferrite arrival suite`.** Counts unloaded chunks inside each view distance every 5 s (~50 us/tick at view distance 10), plus an automated flight bench. `-Pferrite.autobench=x,z,speed,seconds,runs` runs a suite headless. - **`/ferrite probe stages` and `/ferrite pregen order`.** Per-stage wall timer on the chunk pipeline and a selectable pregen request order (ring, scan, diag). Diagnostics only, default off; readings are in docs/JOURNEY.md. ### Fixed - **Own nametag missing in F5 with nametag mods** (#15). A leftover client mixin blanked the local player display name. Removed. ### Changed - **Entity query index and collider skip are now default on.** Opt-in since 0.7.0. Evidence: 10.8M oracle checks with zero mismatches, and a 1022-zombie farm on a shared 4-core server going from 15.5 TPS to a locked 20 TPS. Kill switches: `-Dferrite.entityquery.cache=false` and `-Dferrite.entityquery.colliderskip=false`. With Lithium installed the gain is smaller; the two coexist. - **Lower default-config footprint** (26.2.x dev build, JDK 25, jcmd; commands in docs/PIANO_STATUS.md): - ~4.4 MB of off-heap physics buffers no longer allocate while physics is off. - Rust worker pool starts on first use instead of at the title screen: zero idle native threads, was 6. - Cramming reuses its spatial hash buckets across ticks. - Two leaks closed: parity-capture lists cleared on server stop, and the opt-in nav cache frees native memory on chunk unload. - Monitors stop timing entities while reports are off, removing ~100k allocations/s at horde scale. No measurable mspt change on a 24-core desktop; the saving is GC pressure and slow-CPU time. - **Fabric Loader 0.19.5** in the dev and CI build. Minimum stays 0.18.4.
