You can now block a pull request when its bundle grows by more than a fixed size, such as 1.5 MB, instead of a percentage of the baseline. The allowed increase stays the same as your app grows.
In Settings → Bundles, add or edit a threshold, choose Install size or Download size, and select Absolute size (MB). MB uses decimal units: 1 MB = 1,000,000 bytes.
Existing percentage thresholds are unchanged, including fractional values such as 0.47%. Both types compare against the latest matching bundle on your baseline branch and keep the same GitHub check and approval flow.
See the bundle insights guide for configuration details.
