v0.6.0

Added

• Add Java-compatible health reports and a live health dashboard with background
  uploads, rolling TPS, tick-duration, CPU, world, and ping history, and trusted
  viewer clients.
• Add an optional spark expansion for Endstone PlaceholderAPI with TPS,
  tick-duration, and process/system CPU placeholders. Spark continues to work
  normally when PAPI is not installed or active.
• Add one-hour process-memory history and 1m/5m/15m allocation-rate metrics on
  Windows and Linux, with health show --memory and --network detail views.
• Attribute sampled Python plugin call chains on CPython 3.12+; CPython 3.11
  remains native-only.
• Export active Bedrock behavior-pack metadata and a reviewed safe subset of
  server.properties, with opt-in support for additional safe keys.
• Preserve the initiating player's UUID across profiler, health, activity,
  upload, and recovery metadata.
• Allow /spark profiler open --comment <text> to override the comment shown in
  the live viewer.
• Report the number of ticks included by --only-ticks-over, and distinguish
  samples discarded from an unfinished terminal tick from other incomplete data.
• Improve Windows native symbol attribution for templates, lambdas, local
  classes, and other ambiguous compiler-generated names.
• Support Java-compatible Spark configuration environment variables.

Changed

• Align command parsing, help visibility, profiler action precedence, umbrella
  permissions, and zero-interval defaults more closely with Java spark.
• Align live-viewer updates and profiling windows to stable global cadences, and
  use monotonic deadlines for timed profiles, uptime, ping, and network sampling
  so wall-clock changes or server stalls do not skew them.
• Distribute Linux builds as a single endstone_spark.so. A full server restart
  is recommended when upgrading from the old helper-based runtime or after an
  update that changes Spark's persistent native allocation support.
• BREAKING: Linux allocation profiling now supports allocator providers that
  are part of the server's startup dependency graph. Custom allocator providers
  loaded later at runtime are not supported.
• Improve Windows x64 allocation profiling so plugin unload does not leave native
  callbacks targeting unloaded Spark code.
• Reduce sampler/allocation aggregation overhead, profile-export allocations, and
  peak memory use during crash-recovery replay.
• Make Linux native symbol attribution more conservative by rejecting ambiguous
  evidence instead of presenting uncertain labels as resolved functions.

Fixed

• Improve allocation-profiler cleanup and failure handling on Windows and Linux,
  including Windows stack unwinding and LastError preservation, Linux caller
  attribution, and bounded stop/finalize paths so slow cleanup cannot freeze the
  server indefinitely.
• Keep persistent Linux allocation support safe across plugin unload and late
  callbacks. Incompatible or exhausted process-lifetime state is reported and
  requires a full server restart.
• Make recovery-journal flushing, rotation, and module-definition ordering more
  durable, and retain recovery data when shutdown cleanup is incomplete.
• Preserve independent complete call trees for different threads that share the
  same display name.
• Export Python filename leaves and code identifiers without server-owner
  directory paths while retaining available line information.
• Harden live-viewer and health-dashboard connection lifecycle, reconnects,
  trusted-client validation, malformed input handling, and bounded send/receive
  queues.
• Keep viewer and health notification failures off the server tick path and ensure
  failed connections are cleaned up.
• Include players correctly in aggregate world entity gauges and include world
  metadata in the initial health report.
• Match upstream spark protocol details for profile data version, tick-threshold
  units, and tick-duration placeholder windows and percentile ranks.
• Prevent Spark's native allocation-hook internals from being charged to Spark in
  execution-profile Plugins View.
• Prevent the viewer's process-memory denominator from decoding as zero while
  preserving native RSS/committed-memory semantics.
• Skip unsafe device-metadata ping polling for unauthenticated headless BDS
  clients.
• Keep a completed allocation profile stable until serialization finishes before
  persistent allocation-rate counting resumes.
• Prevent Windows execution sampling failures from leaving the target BDS thread
  suspended.
• Preserve recovery journals when export shutdown cleanup does not complete, and
  report cleanup warnings only when cleanup actually remains incomplete.
