Use the --dry-run flag to see what would be upgraded without actually
performing the upgrade:
$ deno upgrade --dry-run

The --quiet flag suppresses diagnostic output during the upgrade process. When
used with deno upgrade, it will hide progress indicators, download
information, and success messages.
$ deno upgrade --quiet
This is useful for scripting environments or when you want cleaner output in CI pipelines.
Downloaded Deno binaries are cached in $DENO_DIR/dl/. If you reinstall the
same version later, the cached archive is reused instead of re-downloading. For
canary builds, old entries are automatically removed, keeping only the 10 most
recent versions.
Use the --checksum flag to verify a downloaded binary against a known SHA-256
hash. This protects against tampering in CI environments and security-sensitive
setups:
$ deno upgrade --checksum=<sha256-hash> 2.7.0
SHA-256 checksums are published as .sha256sum files alongside release archives
on GitHub:
$ curl -sL https://github.com/denoland/deno/releases/download/v2.7.0/deno-x86_64-unknown-linux-gnu.zip.sha256sum
By default, Deno will upgrade from the official GitHub releases. You can specify
the --canary build flag for the latest canary build:
# Upgrade to the latest canary build
$ deno upgrade --canary
