Version 1.0.0 Released#

This is our first major release.

Major updates:

• There is now an Eclipse plugin for Orc, compatible with Eclipse versions 3.3 and later. It is available from the Downloads page. Thanks go to John Thywissen for his hard work in creating this plugin.
• We have introduced experimental support for exception handling. Exceptions are documented in the user guide. Thanks go to Andrew Matsuoka for his hard work in designing and implementing this feature.
• The static typechecker is now a permanent language feature. It is no longer experimental, though it is still optional to use. It is documented in the user guide.

Minor updates:

• The isolated keyword, which creates isolated actors, is now disabled by default; use -allowIsolated to enable it.
• Parser error reporting has only slightly improved; in particular, the parser will clearly report when an Orc program has no goal expression.
• Relative paths in include are now relative to the file that contains the declaration, rather than an Eclipse workspace or some system default. The -I switch still works as before.
• There is now an equality pattern, =x, which matches against the value bound to x, rather than binding a value to x.
• The AST classes within the compiler have been significantly refactored to improve readability.
