X10 Release 2.6.2
HIGHLIGHTS OF THIS RELEASE
X10 2.6.2 contains updates for new versions of Java and MacOS
- Managed X10 support for Java SE 11
- Native X10 support for current MacOS versions
LIMITATIONS OF THIS RELEASE
The size and index of arrays must be less than 2^31 with Managed X10.
An attempt to allocate a longer array causes IllegalArgumentException.
The following features described in the 2.6 language manual do not
currently work and may be fixed in the subsequent releases:
- Non-static type definitions as class or interface members
(static type defs do work)
The constraint solver used by X10 typechecker is known to be incomplete
for situations in which a constraint implies an infinite number of
distinct constraints.
Additionally, the following features described in the language
manual do not currently work with Native X10.
- Non-final generic instance methods
- Exception stack traces on Cygwin
The generated C++ code requires g++ 4.2 or better to be compiled;
we do almost all of our testing against g++ 4.4.
- On Power/Linux you may either use g++ 4.2 or better
or xlC 11.1 or better.

X10 2.6.1
X10 Release 2.6.1
HIGHLIGHTS OF THIS RELEASE
The focus of the X10 2.6.1 release is improvements to Resilient X10.
Some highlights include:
- Significant improvements to the performance of resilient finish
- A new resilient store implemented in X10
- Improved standard library APIs for elasticity and
non-shrinking recovery. - Enhancements to the x10.util.resilient.iterative package to
exploit elasticity to support non-shrinking recovery. - Updating of all Resilient X10 sample programs and applications
to showcase the improvements in Resilient X10.

SF_RELEASE_2_6_0
X10 Release 2.6.0
HIGHLIGHTS OF THIS RELEASE
The X10 language now includes an overloading mechanism for redefining
or extending the behavior of control structures. For more details,
refer to the language manual section on user-defined control
structures or the X10'16 paper "Control Structure Overloading in X10."
The X10 language now supports trailing closures. A trailing closure is
a closure block that is written and after the parentheses of a
function call. This closure block is passed as a closure without
argument to the function.
To resolve parsing ambiguities, the property keyword is now mandatory
to introduce property methods.
