v1.7.10

Bugfix release that addresses several blockers and regressions.

General

Gradle plugin

• Do not expose Kotlin stdlib in plugin dependencies, this should fix errors like Module was compiled with an incompatible version of Kotlin when using Dokka. Thanks to @​martinbonnin (#​2543)

Java sources

• Fixed build failure caused by having configured source links for Java code (#​2544)
• Fixed several exotic problems that led to build failures, all related to using annotation in Java sources (#​2509, #​2551, #​2350)

v1.7.0

Improvements

Changes

• Support Kotlin 1.6.21

Bugfixes

• Support KLIB libraries for common platform, previously led to ERROR CLASS instead of references in documentation (#​2441)
• Fixed a maven plugin build problem related to coroutines which only occurred in multi-module builds (#​2461)

v5.0.0-alpha.10

2022-06-26

• Fix: Configure the multiplatform artifact (com.squareup.okhttp3:okhttp:3.x.x) to depend on the JVM artifact (com.squareup.okhttp3:okhttp-jvm:3.x.x) for Maven builds. This should work-around an issue where Maven doesn't interpret Gradle metadata.
• Fix: Make another attempt at supporting Kotlin 1.5.31 at runtime. We were crashing on DurationUnit which was a typealias in 1.5.x.
• Upgrade: [Okio 3.2.0][okio_3_2_0].

v5.0.0-alpha.9

2022-06-16

• New: Enforce label length limits in URLs. HttpUrl now rejects URLs whose domains aren't valid. This includes overly-long domain names (longer than 253 characters), overly-long labels (more than 63 characters between dots), and empty labels.
• New: Don't include the Content-Length header in multipart bodies. Servers must delimit OkHttp's request bodies using the boundary only. (This change makes OkHttp more consistent with browsers and other HTTP clients.)
• New: Drop the tunnelProxy argument in MockWebServer.useHttps(). This change only impacts the OkHttp 5.x API which uses the mockwebserver3 package.
• Fix: Don't call toDuration() which isn't available in kotlin-stdlib 1.4.
