Patch notes 2026-07-02

Lily Runtime 0.4.6

Added

• Fentags support. Example: [some_command x_offset=-32 health=42.0] interleaved text [another_command]
• Layout tags. Example: [color rgba(0.8, 0.4, 0.2, 1.0)]
• Evaluation overlay for Swim files produced by demo/evaluation builds.

Changed

• Profiling Report now shows more stats and has ANSI color coding.
• Render now only requests a redraw on about_to_wait instead of directly after a render.

Fixed

• FixedUpdateScheduler now only updates every 16 ms tick. Previously, it updated at least once per render.
• --profiling command line argument now works again. It shows profiling with ANSI colors to stderr. Only works in the dev runtime.

Marsh VM

Added

• New super instructions: BoundsCheck, BoundsCheck.lt, LoadScaled, StoreScaled, b.cmp, cpyN, zeroN, etc. These improve runtime performance slightly.

Experimental

• Intrinsic vec_quick_sort().

Swamp 0.5.14

Added

• Subcommand clean deletes the Swim file target (e.g. lily/bin/main.lily).
• Subcommand check shows analyzer results without lowering or codegen.
• Subcommand aliases b for build and c for check.

Changed

• test subcommand. Test harness now garbles memory before each test so tests do not accidentally rely on zeroed memory.

• swamp.yini now requires a type field. Use :main (for games) or :lib (for packages).

Experimental

• codegen.use_branch_fusing and lowering.use_super_instructions flags in swamp.yini.
• quick_sort() for ordered collections (Vec). It only works with *very* limited syntax and only for Int right now.

Swamp LSP

Added

• buildOnSave, pretendInteractive, and showDebug options.

Experimental

• The LSP server now registers dynamic file watchers for **/*.sw and **/*.swamp for clients that support it.

Sprout 0.0.5

Changed

• Branch and tag dependencies now resolve to concrete commit hashes more reliably.
• sprout.lock now skips rewriting the file when the dependencies remains the same.

Strata

Fixed

• Intrinsic map.remove now detects when a trap is issued.
• Wrap-like collections now copy properly to Vec collections.
