Cumulative Fix Pack
Adobe introduced a single-delivery model for releasing fixes. Instead of releasing hot fixes for individual issues, Adobe now releases a Cumulative Fix Pack (CFP) every month (subject to passing quality checks). A CFP is an aggregated content package for multiple fixes. CFPs primarily include bug fixes but might also include Feature Packs.
The key highlights of this Cumulative Fix Pack are:
- Adapted Analytics Classic UI configuration for secret input.
- Fixes for independent persistence cache for Contexthub.
- Accurate computation of Asset dimensions.
- Optimized AEM performance when publishing assets to Brand Portal.
- Fixes in Resourcetype value in canvas node.
- Enabled case-sensitive and special characters search functionality for document fragment content.
- Enhanced Adaptive Forms to attach PDF as attachments in Safari.
- Provides a new Dynamic Media that connects to the new Dynamic Media Publishing Infrastructure for faster and more scalable replication.
