1.1.0 (2026-11-05)

Changed

• 1.1.0 refuses snapshots, tapes and containers from 1.0.x. The
  snapshot keeps format 6, the journal tape format 7 and the replay
  container format 4, but they carry M3_ABI_VERSION, which now names
  1.1, so 1.1.0 refuses a snapshot, tape or container that 1.0.x wrote
  with m3_errorVersion. m3CreateWorld refuses a def from 1.0
  headers the same way: rebuild against the 1.1 headers. The shared
  library's SOVERSION is 1.1.
• A blast inside a shape pushes its body toward its centre of mass.
  When the blast of m3World_Explode lay inside a shape, its rounding
  included, the body was pushed from the blast toward a point of that
  shape, with the impulse applied there. That point was a sphere's centre,
  the middle of a capsule's segment, or the average of a hull's
  vertices. A lopsided hull, or a body with several shapes, therefore
  spun for no physical reason. A blast exactly at that point pushed
  along the shape's own x axis. Now the push runs from the blast to the
  body's centre of mass, as maul2d's does, so it spins nothing, and a
  blast at the centre of mass itself pushes nothing; the body still
  wakes. m3World_Explode, and a replay of a journaled explosion, can
  give a different velocity to a body one of whose shapes holds the
  blast. A shape the blast is outside of is pushed as before.

Fixed

• A mesh create no longer takes seconds on a fan. The edge flags a
  mesh bakes on create found each edge's neighbor by scanning every
  triangle around one of its vertices, so a fan of triangles around one
  vertex took time quadratic in its size: about 5.4 s for 65533
  triangles. The bake now takes time linear in the mesh, about 0.025 s
  for the same fan, and gives the same flags byte for byte, so no
  contact or result changes. The same holds for a mesh create that
  m3World_ReplayJournal replays.
  (#413)
• Restore refuses a voxel chunk whose cells disagree. An occupied
  cell always has a fill of 1 to 255, and an empty cell has fill 0 and
  payload 0. m3World_Restore refused neither an occupied cell with
  fill 0 nor an empty cell with a fill or a payload, and
  m3World_ReplayJournal took the same states from a chunk create
  record. Both now refuse such a chunk with m3_errorFormat, and
  restore leaves the world as it was. No chunk the library writes is
  refused.
  (#409)
• Restore refuses a wheel direction that is not unit length. A
  vehicle create takes a wheel direction whose squared length lies
  between 0.81 and 1.21 and stores it normalized, but restore took any
  stored direction in that band, so a restored wheel could push along
  a scaled direction. Restore now requires the squared length within
  1e-5 of 1, about 24 times what normalizing leaves, and refuses
  anything else with m3_errorFormat.
  (#415)
• Restore refuses mesh edge flags the mesh would not bake. A mesh's
  edge flags are derived from its geometry, and contact welding reads
  them, but restore took them as stored. Restore now bakes each mesh's
  flags again and refuses a snapshot whose flags differ, with
  m3_errorFormat, or m3_errorCapacity when it cannot allocate the
  bake's scratch. No snapshot the library writes is refused. On the
  largest mesh the limits allow, 65522 triangles, a restore took about
  26 to 29 ms with the check against 22 ms without it.
