+# Changelog - zcatsql
+
+Todos los cambios notables en esta librería se documentan aquí.
+
+---
+
+## [Unreleased]
+
+### Added
+
+- **2026-01-08:** Export de módulo para dependientes externos
+  - Añadida línea `b.modules.put("zcatsql", zcatsql_mod)` en build.zig
+  - Permite que otros proyectos usen zcatsql como dependencia via build.zig.zon
+  - Ejemplo de uso en Solo2 backend (waitlist)
+  - **Cambio realizado por:** Conversación Solo2
+  - **Motivo:** El módulo se creaba internamente pero no se exportaba, impidiendo su uso como dependencia externa
+
+---
+
+## Notas de uso como dependencia
+
+Para usar zcatsql en otro proyecto:
+
+**build.zig.zon:**
+```zig
+.dependencies = .{
+    .zcatsql = .{
+        .path = "ruta/a/zcatsql",
+    },
+},
+```
+
+**build.zig:**
+```zig
+const zcatsql_dep = b.dependency("zcatsql", .{
+    .target = target,
+    .optimize = optimize,
+});
+
+const root_mod = b.createModule(.{
+    .root_source_file = b.path("src/main.zig"),
+    .target = target,
+    .optimize = optimize,
+    .imports = &.{
+        .{ .name = "zcatsql", .module = zcatsql_dep.module("zcatsql") },
+    },
+});
+```
