v10.1.5

10.1.5 is the sixth release in the 10.1.x series of Akka HTTP.

It is mainly a mitigation for the DoS vulnerability when using decodeRequest

Migration Notes

To avoid excessive memory usage we introduced two new limits that apply per default:

• akka.http.routing.decode-max-size: This limit applies when you use decodeRequest to limit the amount of decompressed data. The default limit is 8 megabytes.
• akka.http.parsing.max-to-strict-bytes: This limit applies when you use HttpEntity.toStrict or the toStrictEntity directive (and related directives). It will only collect up to the given amount data and fail otherwise. The default limit is 8 megabytes.

Depending on your application requirements, you may want to change these settings.
