libdex 1.2.alpha
================

This is an alpha release for the upcoming GNOME 51.

 * Dropped the gconstructor for `dex_init()` which means applications must
   call `dex_init()` at startup themselves from `main()`.
 * New DexLimiter API for bounded concurrency with explicit
   acquire/release, automatic permit management while running fibers, and
   close/reject behavior for queued work
 * New timeout wrappers for futures: dex_future_with_timeout(),
   dex_future_with_timeout_msec(), dex_future_with_timeout_seconds(), and
   dex_future_with_deadline()
 * Additional GFile async wrappers for temporary directories, copy with
   progress, trash, append, partial content loading, byte loading,
   filesystem info queries, default handler lookup, enclosing mount lookup,
   display-name changes, read/write open/create/replace variants, string
   content replacement, and symbolic link creation
 * Additional GIO async wrappers for GAppInfo, GDataInputStream,
   GOutputStream, GSocketClient, GSocketConnection, GTlsConnection,
   GDtlsConnection, GResolver, GNetworkMonitor, GProxy, GProxyResolver,
   GSubprocess, GTlsDatabase, GTlsInteraction, GPermission, and
   GUnixConnection
 * New DexCoroutine stackless future type with helpers for suspending on
   pending futures, plus dex_scheduler_spawn_coroutine()
 * New DexTaskGroup API for structured concurrency with close, cancel, and
   cancel-on-error behavior
 * New DexThreadPool API for bounded threaded work queues
 * New dex_limiter_run_on_pool(), dex_limiter_run_coroutine(), and
   dex_limiter_close_after_drain()
 * New dex_aio_open() and dex_aio_close()
 * New dex_fiber_yield()
 * New DEX_DEFINE_CLOSURE_TYPE() helper for closure-like state structs
 * New dex_set_object() helper and DexObject property support for DexFuture
   values
 * New dex_promise_resolve_enum()
 * New DexStateMachine API to simplify asynchronous state machines with fibers
   providing a simple API to track state machine transitions.
 * Future debug names are now enabled by default when compiling with GCC and
   fibers emit Sysprof marks for their duration
 * Fix DexObject weak-reference retargeting to avoid a possible lock
   inversion during finalization
 * Fix DexChannel receive_all() to unblock queued senders after draining
   bounded channel capacity
 * Fix DexDelayed chaining so release waits for the wrapped future in the
   correct direction
 * DexPosixAioBackend now delays threadpool startup until the first work item
   is enqueued.
 * Make DexSemaphore user-space only
 * Build system fixes for gio-unix dependency propagation
 * Fix clang testsuite compatibility around atomic addition
 * Documentation additions for limiters, timeout-gated futures, coroutines,
   task groups, thread pools, schedulers, debugging, and GIO wrappers
 * Testsuite additions for limiters, timeout passthrough behavior, delayed
   futures, channel receive_all(), weak-reference retargeting, GIO wrappers,
   AIO, coroutines, fibers, task groups, thread pools, DexObject, and
   DexTest helpers
