v1.2.0

Security

• fix(security): set body limit to 50mb to prevents memory exhaustion from oversized payloads
• fix(security): replace shell cleanup with node fs apis that eliminates command injection
  surface
• fix(security): sanitize error responses, strips stack traces and internals from
  client-facing errors
• fix(security): validate locale input

Performance

• fix(performance): parallelize page reset, runs cleanup operations concurrently between
  renders
• fix(performance): optimize sharp pipeline, reduces unnecessary buffer copies in image
  processing
• fix(performance): add html capture resource cache, avoids redundant network requests for
  repeated resources
• fix(performance): fix video double io, eliminates redundant file read/write in video
  capture
• fix(performance): remove single-process chrome flag

Memory

• fix(memory): free screenshot buffer after sharp init
• fix(memory): aggressive page reset, clears page state more thoroughly to prevent leaks
• fix(memory): add 500mb html capture limit, prevents OOM on large pages
• fix(memory): fix video file orphaning, ensures temp files are cleaned up
• fix(memory): fix video deletion race condition
• fix(memory): reduce capture function params
• fix(memory): lazy-load cookie constants

Scalability

• fix(scalability): dynamic pool sizing, adjusts browser pool based on system resources
• fix(scalability): configurable recycling thresholds, environment variable driven instance
  recycling
• fix(scalability): block startup until warmup, gates requests until pool is ready

Code Quality

• fix(code): consistent error handling, unified error handling across all render types
• fix(code): handle in-flight requests on shutdown
• fix(code): add shutdown timeout
• fix(code): fix validation error parsing
• fix(code): handle malformed json in get config
• fix(code): extract magic numbers to constants
• fix(code): remove unused cache properties
• fix(config): env-var driven configuration
• fix(code): structured logging with pino
• docs: add comprehensive jsdoc

Refactoring

• refactor(browser-pool): remove dynamic scaling logic and related properties
• refactor(browser-pool): remove shutdown handler and improve promise handling

Testing

• feat(unit tests): add comprehensive unite test suite for rendering and browser pool
  functionality
• feat(tests): implement end-to-end tests for API rendering and add new test configurations, validates output format correctness via magic bytes (PNG, JPEG, WebP, PDF, MP4)
• feat(ci): add GitHub Actions workflow for unit and end-to-end testing, runs on every push with 95% coverage gate and Docker-based E2E

Dependencies

• chore(deps): update dependencies in package.json and package-lock.json
• chore(deps): add @vitest/coverage-v8 and update package.json scripts for coverage testing
