## [1.3.0] — 2026-08-08
Minor release carrying a **breaking API change** to CORS configuration. The framework is
private with controlled consumers, so this ships in the 1.x line with a loud compile break
instead of a v2 module-path (`/v2`) migration.
### Removed
- **⚠️ BREAKING: `web.Config.AllowedOrigins` removed.** CORS origins now have a single
home: `server.Config.CORSOrigins` (env `EINHERJAR_SERVER_CORS_ORIGINS`). The field was
env-backed through v1.1.x and a code-only override in v1.2.0 — reading it after the env
tag moved silently served *no* CORS. Removing it turns that runtime trap into a compile
error.
**Migration:** replace `cfg.Web.AllowedOrigins` with `cfg.Server.CORSOrigins`, and
`web.Config{AllowedOrigins: o}` with `web.Config{Server: server.Config{CORSOrigins: o}}`
— or just let `web.New` read `EINHERJAR_SERVER_CORS_ORIGINS`. The MCP flags any leftover
reference (`validate_snippet` rule `web.allowedorigins-removed`).
### Changed
- Bumped `contracts`, `core` to v1.3.0.
## [1.2.0] — 2026-08-08
Minor — CORS configuration moved to its rightful struct; `web.New` made safe-by-default.

With origins set in code (CORS auto-applied). `Server.CORSOrigins` is the single
source of truth — normally it loads from `EINHERJAR_SERVER_CORS_ORIGINS`, but you
can set it directly to override without the env var:
```go
srv := web.New(logger, web.Config{
Server: server.Config{Port: 9090},
AllowedOrigins: []string{"https://example.com"},
