Non-Upwards Compatible Changes

CapTP protocol changes

In order to fix the Inappropriate "the donor is gone" bug, I made an incompatible change to the CapTP protocol: the addition of the donorPath to the acceptFrom messages.

Syntax changes

Reserved some new keywords: "datatype", "fn", "fun".

An assignment-level statement in the collection position of a for-loop now requires parens.

for i in (def coll := foo()) {

New features

Experimental extra sugared forms of when-catch

See "experimental extra sweet when-catch syntaxes"

Experimental sugar-free form of when-catch

See "User Defined Control Flow"

Forward declaration may now appear at right end of assignment without parens

? def r := def p
# value: <Resolver>

Slightly better tracing

Setting TraceLog_causality=event will now trace exceptions that caught by an E try-catch and that escape a deflector.

Help is now sorted

Newly tamed classes

Thanks to Kevin Reid and Marc Stiegler

Newly iteratable classes


So, assuming it was correct not to suppress Charset#availableCharsets/0 above, we can enumerate it:

? def x := <import:java.nio.charset.Charset>.availableCharsets()

? for k => v in x {
>     println(`$k => $v`)
>     if (k[0] > 'E') { break }
> }
# stdout: Big5 => Big5
#         Big5-HKSCS => Big5-HKSCS
#         EUC-JP => EUC-JP
#         EUC-KR => EUC-KR
#         GB18030 => GB18030
