## Notable changes to Cloud Disk, newest first.

**Beta**  
Cloud Disk is in beta and under active development, so behavior and defaults may change between releases.

## 2026-06-24  
- Cloud Disk now caps its own memory use automatically, keeping the daemon's footprint predictable without manual tuning.

## 2026-06-22  
- **Kubernetes (CSI):** non-root pods can now read and write Cloud Disk volumes.  
- **Kubernetes (CSI):** volume provisioning is now strongly consistent — a newly created volume is immediately usable.  
- Discarding/`TRIM` now reclaims space within partially written chunks, not just whole ones.

## 2026-06-19  
- **Write-back caching is now the default**, so writes are acknowledged from the local cache and flushed to Tigris in the background — noticeably faster for write-heavy workloads. Opt into write-through if you need every write durable on Tigris before it's acknowledged. See [Configuration & Tuning](/content/docs/cloud-disk/tuning/index.html).
- Reads are now strongly consistent: data you just wrote is always reflected, even across mounts.

## 2026-06-17  
- **Crash-consistent write-back across hosts:** after an unclean shutdown you can remount the disk — including on a different machine — and it recovers cleanly, without losing acknowledged writes.  
- New `-preset` option to pick a performance profile when creating a disk.

## 2026-06-15  
- New `cloud-disk resize` command to grow a disk; the filesystem expands on the next mount.

## 2026-06-12  
- **Faster cold starts:** the cache pre-warms and reads ahead automatically, so the disk is responsive sooner after mounting.  
- CLI improvements: mount and unmount show progress, a `status` command reports a disk's state, config defaults are clearer, and a `version` command was added.
