## [0.4.0] - 2026-01-14

+10

### Added

+11

+12

- Added full macro hygiene support for syntax-rules and syntax-case. Macros now properly respect lexical scope, preventing accidental variable capture that could cause subtle bugs. This release also adds `free-identifier=?` for comparing identifiers in macro expansion, and the `#'` reader shorthand for `(syntax ...)` expressions.

+13

- Added native C implementations of list operations (`assoc`, `assq`, `assv`, `member`, `memq`, `memv`) that were hotspots during macro expansion. This results in 2x faster test suite execution and 50% faster module compilation.

+14

- Added ability for `guard` to catch VM-level errors such as type errors, division by zero, and out-of-bounds access. Previously these errors would terminate the program; now they can be handled gracefully using the new `vm-error?` predicate in `(sigil error)`.

+15

- Added CPU and memory profiling infrastructure via the new `(sigil profile)` module. Developers can now measure execution time and memory allocation to identify performance bottlenecks in their applications.

+16

- Added keyword argument support to `make-http-server` and `http-serve`. Server configuration is now cleaner and more readable, with named parameters like `port:`, `host:`, and `handler:` instead of positional arguments.

+17

- Added `sxml->html` function for converting SXML trees to HTML strings. This complements the existing `html->sxml` parser, enabling round-trip HTML processing and programmatic HTML generation.

+18

- Added new sigil-version package containing the `(sigil version)` module for semantic version parsing and comparison. Applications can now parse version strings, compare versions, and check compatibility constraints programmatically.

+19

+20

### Fixed

+21

+22

- Fixed source file names in error stack traces. Errors now display the correct file path with line and column positions (e.g., `main.sgl:3:15`), making debugging significantly easier.

+23

- Fixed `with-api-docs` to correctly resolve package-centric documentation paths. API documentation generation now works correctly for all package layouts.

+24

- Fixed missing package dependency declaration that could cause import errors when using sigil-irc in isolation.

+25

- Fixed socket API issues and improved documentation. Socket operations now behave more consistently across platforms.

+26

+27

### Other

+28

+29

- Reduced release binary size from 3.2MB to 1.8MB through build optimizations. Smaller binaries mean faster downloads and reduced disk usage for deployed applications.

+30

- BREAKING: Renamed UI components from sigil-* to sg-* prefix (e.g., sigil-button becomes sg-button) to mirror data-sg-* attributes. Also exported HTTP method symbols and simplified middleware composition with with-* helpers.
