Release Notes

Kotlin/kotlinx.serialization (org.jetbrains.kotlinx:kotlinx-serialization-json)

v1.11.0

==================

This release is based on Kotlin 2.3.20 and provides new Json exceptions API and some bugfixes and improvements.

Expose Json exceptions structure

To make working with exceptions easier and providing proper error codes in e.g., REST APIs,
classes JsonException, JsonDecodingException, and JsonEncodingException are now public.
They have relevant public properties, such as shortMessage, path, offset, and others.
This API is currently experimental, and we're going to improve it further in the subsequent releases.
See the linked issues for the details: #​1930, #​1877.

Ability to hide user input from exception messages for security/privacy reasons.

Historically, exception messages in kotlinx.serialization often included the input Json itself for debuggability reason.
Such behavior may pose additional challenges for logging, analytics, and other systems, since
a system is not always allowed to store user data due to privacy/security reasons, which imposes additional sanitation logic.
To address this issue, a new property exceptionsWithDebugInfo is added to JsonConfiguration.
Disable it to hide user input from exception messages.
IMPORTANT: This behavior will be enabled by default when this property becomes stable.
See #​2590 for more details.

Bugfixes and improvements

• CBOR: Relax value range check when decoding numbers (#​3167)
• Use a specialized writeDecimalLong method for IO stream integrations in Json (#​3152)

v0.7.4

Compare Source

Added

• Recomposition Profiler: Timing measurement (Issue #​89)
  • @TraceRecomposition now measures composable recomposition duration via System.nanoTime() IR injection
  • Duration displayed in logcat output: [Recomposition #​3] UserCard (2.30ms)
  • Compiler plugin wraps composable body in try-finally for accurate timing even on exceptions
  • RecompositionEvent.durationNanos field added for custom logger consumption
  • KMP-compatible via expect/actual currentNanoTime() (Android/JVM supported, other platforms gracefully skip)
• Heatmap Tooltip — Hover over recomposition count inlay in the editor to see:
  • Last recomposition duration
  • Parameter changes with old/new values
  • State changes with old/new values
  • Unstable parameter summary
  • Cumulative total recomposition count and duration
• Heatmap logcat parser updates — Parses [param] and [state] prefixed lines and duration from log output

Changed

• Shadow plugin upgraded to 9.0.0-beta12 for Gradle 9.x compatibility (plugin ID changed from com.github.johnrengelman.shadow to com.gradleup.shadow)

v0.7.3

Compare Source

Added

• Stability configuration file support for stabilityDump (Issue #​130, PR #​105)
  • stabilityConfigurationFiles now applies to both stabilityDump and stabilityCheck tasks
  • Types matching configuration patterns are overridden to STABLE in the baseline file
  • Composable skippable flag is recalculated based on resolved parameter stability
• unstableOnly option for stability baseline (Issue #​128)
  • New unstableOnly option: when enabled, only unstable composables are included in the baseline file
  • Reduces baseline file size in large projects and focuses on stability issues
• New composable diff now includes parameter-level stability details (PR #​105)
  • stabilityCheck output for new composables shows each parameter's stability status
• Internal state change tracking for @TraceRecomposition (Issue #​89)
  • New traceStates annotation parameter: @TraceRecomposition(traceStates = true)
  • Tracks mutableStateOf, mutableIntStateOf, derivedStateOf and other Compose state changes
  • Compiler plugin detects delegated state variables via IrLocalDelegatedProperty IR analysis
  • Logs state changes with [state] prefix, parameter changes with [param] prefix
  • Only changed states are logged to reduce noise

Fixed

• ignoredPackages now consistently respected during stabilityCheck (Issue #​129)
  • Previously, composables in ignored packages were excluded from stabilityDump but still detected as "new composable" during stabilityCheck
  • Now both tasks apply the same package/class filtering
• @Optional annotation added to stabilityConfigurationFiles task input (PR #​105)
  • Prevents Gradle task validation failure when configuration files are not set
• ADB not found on Windows (Issue #​139)
  • Fixed adb.exe detection on Windows for the Heatmap feature
  • Added Windows default SDK path (%LOCALAPPDATA%\Android\Sdk)
  • Uses where command instead of which on Windows for PATH lookup

• Tool window icon updated — Changed from monochrome gray to blue color matching the plugin icon
• Stability comparison logic extracted to StabilityComparison.kt (PR #​105)
• Stability configuration parser added as StabilityConfigParser.kt (PR #​105)
