v5.2.2

5.2.2 (2025-06-03)

Bug Fixes

• "Overlay enabled" false positive (18e72ee)
• do not crush when error is null for runtime errors (#5447) (309991f)
• remove unnecessary header X_TEST (#5451) (64a6124)
• respect the allowedHosts option for cross-origin header check (#5510) (03d1214)

v5.2.1

5.2.1 (2025-03-26)

Security

• cross-origin requests are not allowed unless allowed by Access-Control-Allow-Origin header
• requests with an IP addresses in the Origin header are not allowed to connect to WebSocket server unless configured by allowedHosts or it different from the Host header

The above changes may make the dev server not work if you relied on such behavior, but unfortunately they carry security risks, so they were considered as fixes.

Bug Fixes

• prevent overlay for errors caught by React error boundaries (#5431) (8c1abc9)
• take the first network found instead of the last one, this restores the same behavior as 5.0.4 (#5411) (ffd0b86)

v5.2.0

5.2.0 (2024-12-11)

Features

• added getClientEntry and getClientHotEntry methods to get clients entries (dc642a8)

Bug Fixes

• speed up initial client bundling (145b5d0)

v5.1.0

5.1.0 (2024-09-03)

Features

• add visual progress indicators (a8f40b7)
• added the app option to be Function (by default only with connect compatibility frameworks) (3096148)
• allow the server option to be Function (#5275) (02a1c6d)
• http2 support for connect and connect compatibility frameworks which support HTTP2 (#5267) (6509a3f)
