 #### Enhanced DAG-Shaping Controls for `ipfs add`
 
-This release advances CIDv1 support by introducing fine-grained control over UnixFS DAG shaping during data ingestion with the `ipfs add` command. Kubo now allows users to customize the maximum number of links in per UnixFS block/chunk.
+This release advances CIDv1 support by introducing fine-grained control over UnixFS DAG shaping during data ingestion with the `ipfs add` command.
+
+Wider DAG trees (more links per node, higher fanout, larger thresholds) are beneficial for large files and directories with many files, reducing tree depth and lookup latency in high-latency networks, but they increase node size, straining memory and CPU on resource-constrained devices. Narrower trees (lower link count, lower fanout, smaller thresholds) are preferable for smaller directories, frequent updates, or low-power clients, minimizing overhead and ensuring compatibility, though they may increase traversal steps for very large datasets.
+
+Kubo now allows users to act on these tradeoffs and customize the width of the DAG created by `ipfs add` command.

+The release updated configuration [profiles](https://github.com/ipfs/kubo/blob/master/docs/config.md#profiles) to incorporate these new `Import.*` settings:
 - Updated Profile: `test-cid-v1` now includes current defaults as explicit `Import.UnixFSFileMaxLinks=174`, `Import.UnixFSDirectoryMaxLinks=0`, `Import.UnixFSHAMTDirectoryMaxFanout=256` and `Import.UnixFSHAMTDirectorySizeThreshold=256KiB`
 - New Profile: `test-cid-v1-wide` adopts experimental directory DAG-shaping defaults, increasing the maximum file DAG width from 174 to 1024, HAMT fanout from 256 to 1024, and raising the HAMT directory sharding threshold from 256KiB to 1MiB, aligning with 1MiB file chunks.
