# Changelog

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[​](#2026-06-24 "Direct link to 2026-06-24")

* Cloud Disk now caps its own memory use automatically, keeping the daemon's footprint predictable without manual tuning.

## 2026-06-22[​](#2026-06-22 "Direct link to 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[​](#2026-06-19 "Direct link to 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](/docs/cloud-disk/tuning/.md).
* Reads are now strongly consistent: data you just wrote is always reflected, even across mounts.

## 2026-06-17[​](#2026-06-17 "Direct link to 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[​](#2026-06-15 "Direct link to 2026-06-15")

* New `cloud-disk resize` command to grow a disk; the filesystem expands on the next mount.

## 2026-06-12[​](#2026-06-12 "Direct link to 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.
