0.1.4

Released on 2026-10-12.

Serc 0.1.4 reduces compilation, assembly, and serialization overhead.

Performance

• Reduce compilation memory use by deferring full provenance allocation for
  linear scopes (#1252;
  #1252)
• Speed up marshal serialization by indexing the occurrence stream directly
  (#1242; #1242)
• Reduce name and metadata allocations by reusing interned names and the
  compiler’s name index (#1231;
  #1231) (#1235;
  #1235)
• Reduce name-cache initialization, lookup, and memory overhead
  (#1234; #1234)
  (#1241; #1241)
• Speed up assembler graph processing by indexing fusion-owner boundaries and
  avoiding unnecessary cold-block and reversed-store scans (#1236;
  #1236) (#1253;
  #1253) (#1255;
  #1255)
• Reduce swap optimization work by indexing instructions from the first swap
  (#1250; #1250)
• Reduce compiler setup overhead by initializing state directly in its final
  heap allocation (#1243;
  #1243)
• Speed up source-location and scope-exit lookups (#1251;
  #1251) (#1256;
  #1256)
• Skip long-decimal pre-scanning for source files too short to exceed the
  parsing limit (#1257;
  #1257)
• Reduce small-code encoding overhead by avoiding instruction copies
  (#1254; #1254)
