# 4.3 Entrador
Chevereto v4.3, codenamed Entrador (opens new window), delivers major improvements in caching, upload handling, and metadata management. This release introduces Cloudflare Turnstile captcha, chunked uploads, lossless JPEG auto-orientation, and metadata removal. User experience is enhanced with new avatar styles, and several application-level caches have been implemented to boost performance. The update also adds GoPro 360 photo support, important bug fixes, removal of deprecated features, and database optimizations, making Chevereto more efficient and user-friendly than ever.
# Application-level cache
Chevereto is now faster.
Application-level caching stores frequently accessed data in memory, reducing repeated database queries. This improves performance, speeds up page loads, and decreases server load, especially for data that doesn't change often.
# Chunked uploads
Upload large files reliably.
Chevereto now supports chunked uploads, allowing users to upload large files in smaller parts. This is especially useful for high-resolution images or videos, and improves reliability and performance in environments with limited bandwidth or unstable connections.
# Lossless JPEG handling
Pixel perfect bitmaps.
Chevereto now supports lossless JPEG auto-orientation, automatically adjusting JPEG orientation based on EXIF data. It can also remove EXIF data losslessly during upload, preserving the original image quality.
# Semantics for file, tag, and video
Thank you, but I prefer it my way.
Chevereto now includes custom semantics for file, tag, and video management. This enables better organization and categorization of uploaded content, making it easier to manage and retrieve files based on specific criteria.
# GoPro 360 photos
Immersive 360° content.
Chevereto now supports GoPro 360 photos, allowing users to upload and share immersive 360-degree images captured with GoPro cameras. This feature enhances the platform for users who want to showcase 360-degree content with the built-in viewer.
# Cloudflare Turnstile captcha
Enhanced privacy and protection.
Chevereto expands anti-bot protection by adding Cloudflare Turnstile (opens new window) alongside reCAPTCHA v2, v3, and hCaptcha. This gives users more flexibility in choosing a CAPTCHA solution, whether prioritizing ease of use, privacy, or bot mitigation. Turnstile's privacy-friendly, frictionless approach aligns with Chevereto's commitment to user experience, offering a seamless alternative without Google dependencies.
# Environment changes
The following environment variables have been added or modified:
CHEVERETO_MAX_UPLOAD_SIZE

CHEVERETO_MAX_CHUNK_UPLOAD_SIZE
With the introduction of chunked uploads we added this variable for being able to defines the maximum chunk size for chunked uploads (the chunk). The value must be within the limit set by both CHEVERETO_MAX_POST_SIZE and CHEVERETO_MAX_UPLOAD_FILE_SIZE.
CHEVERETO_ENABLE_API_USER
The availability of the user API is now controlled by this variable.
CHEVERETO_MAX_LISTING_ITEMS_PER_PAGE

CHEVERETO_MAX_TAGS
With this new variable we can control how many tags can be created in the system.
CHEVERETO_CACHE_STAMPEDE_SLA
This variable defines the amount of time, in milliseconds, cache guarantees protection. This is a performance optimization to avoid cache stampedes.
