2022 __TOC__ This is an overview of the major features that are available in Ada 2022, the most recent version of the Ada standard. Summary of what's new New profile Jorvik is a subset of the Ada tasking capabilities, similar to Ravenscar and which imposes fewer restrictions, removing the following ones compared to the Ravenscar profile: No_Implicit_Heap_Allocations No_Relative_Delay Simple_Barriers Max_Entry_Queue_Length => 1 Max_Protected_Entries => 1 No_Dependence => Ada.Calendar No_Dependence => Ada.Synchronous_Barriers New syntax Assignment target name @ Square brackets for array aggregates Default initial conditions for types Default generic parameters Declare expressions Reduction expressions Iteration filters Generalized literals New keywords parallel New pragmas Admission_Policy All_Calls_Remote Conflict_Check_Policy Elaborate_Body Generate_Deadlines Preelaborable_Initialization Preelaborate Profile now supports the Jorvik profile Pure Remote_Call_Interface Remote_Types Shared_Passive New aspects Aggregate Allows_Exit Default_Initial_Condition Dispatching Elaborate_Body Full_Access_Only Global Global'Class Integer_Literal Iterator_View Max_Entry_Queue_Length No_Controlled_Parts No_Return (for functions) Nonblocking Parallel_Calls Parallel_Iterator Preelaborable_Initialization Put_Image Real_Literal Relative_Deadline Stable_Properties Stable_Properties'Class Static Static_Predicate String_Literal Synchronization Use_Formal Yield New attributes 'Enum_Rep 'Enum_Val 'Index 'Object_Size 'Parallel_Reduce 'Preelaborable_Initialization 'Put_Image 'Reduce 'Relative_Deadline New packages Atomic_Operations: System.Atomic_Operations.Exchange System.Atomic_Operations.Test_And_Set System.Atomic_Operations.Integer_Arithmetic System.Atomic_Operations.Modular_Arithmetic Big Numbers: Ada.Numerics.Big_Numbers.Big_Integers Ada.Numerics.Big_Numbers.Big_Reals Containers: Ada.Containers.Bounded_Indefinite_Holders See also Wikibook Ada Programming/Ada 83 Ada Programming/Ada 95 Ada Programming/Ada 2005 Ada Programming/Ada 2012 Ada 2022 *Ada 2022 *Ada 2022
