================ Duktape releases ================ Released ======== 0.1.0 (2013-02-14) ------------------ * Initial alpha release * Core features work: compiler, executor, regexps, garbage collection * Most built-ins incomplete or missing 0.2.0 (2013-02-27) ------------------ * Built-ins implemented: Boolean, Date, JSON * Date built-in has initial, minimal local time / locale support * Initial internal documentation: regexp, datetime, json 0.3.0 (2013-03-16) ------------------ * Built-ins implemented: global object, Object, String 0.4.0 (2013-03-31) ------------------ * Built-ins: Array, Number, completing built-ins 0.5.0 (2013-05-17) ------------------ * Built-in number conversion primitives * Cleanup built-ins, improve test cases for built-ins 0.6.0 (2013-09-21) ------------------ * First round of public API cleanup, and add basic API documentation * First version of duktape.org website 0.7.0 (2013-10-30) ------------------ * Traceback support improved * Clean up and document error object properties * Add prototype objects for buffer and pointer values, and make them object coercible * Proper support for big, little, and "middle endian" environments * Single file combined source distributable * Portability and bug fixes 0.8.0 (2013-12-18) ------------------ * Remove DUK_PROFILE model, explicit DUK_OPT_xxx feature options added for tuning the build (see web docs) * Register shuffling added to compiler which mostly eliminates constant and temporary register limits * Reduce code footprint, make built-in data 'const' so that it compiles into the 'text' section * Augment errors created when a built-in error constructor is called as a normal function (e.g. "var e = Error('test')") * Enforce string/buffer length limits to avoid corner cases with strings and buffers close to size_t limit * Ecmascript E5.1 test cases and fixes * Mark-and-sweep stringtable leak fixed, affected mostly builds without reference counting * Run a few mark-and-sweep passes in duk_destroy_heap() to give finalizers a chance to run in most (but not all) cases * Coroutine yield fixes * Portability and bug fixes 0.9.0 (2014-02-02) ------------------ * Added duk_gc() API call to force GC, implemented duk_map_string() and duk_decode_string() * Added extended JSON format variants JSONX and JSONC; NULL pointer values string now coerce to "null" instead of e.g. "(nil)" to match JSONX format * Added input line number to compiler error messages (e.g. SyntaxErrors) * Added support for function declarations outside function or program top level (also known as "function statements"), with V8-like semantics * Renamed __duk__ to Duktape for more consistency with Ecmascript conventions, and made the following cleanups: - removed somewhat useless 'build' - added 'env' - replaced 'addr' and 'refc' with 'info' which gives more internal info - merged 'setFinalizer' and 'getFinalizer' into a single 'fin' call - compatibility properties available for now (e.g. __duk__), but will be removed after this release * Removed array size limit for very large array joins * Improve Unicode handling of Greek final sigma * Make mark-and-sweep interval relative to current heap size (measured as combined object and string count) * Add DUK_OPT_NO_VOLUNTARY_GC to disable voluntary mark-and-sweep entirely; this is useful in timing sensitive applications like games * Preliminary internal support for periodic bytecode executor interrupts which can be used to implement executor step limits, profiling, and debugging * More feature options for build tuning * More self tests to detect obscure compiler bugs, two's complement arithmetic, etc (enable with DUK_OPT_SELF_TESTS) * Fixed several compile warnings, fixed warnings generated by GCC -Wextra * Fixed some incorrect assertions (with no underlying bug) * Fixed a coroutine termination bug which caused assertion errors and occasional segfaults when an uncaught error terminated a thread with a catch point active * Fixed a tailcall bug: the current activation was not closed which caused variable lookups to fail if an inner function accessed variables in the surrounding activation * Fixed a few bound constructor bugs * Fixed handling of "get" and "set": they were handled as reserved words which prevented valid statements like "var set = 1;" * Fixed a switch-case bug where code was accepted before the first case/default clause * Fixed a switch-case bug where successive case clauses with no code in-between was not handled correctly * Fixed a for statement control flow bug when the third clause of the for statement was empty and a continue was used * Fixed error lineNumber bug triggered when there was more than 127 source lines between successive compiled statements * Fixed some line terminator handling issues * Fixed relational operator ToPrimitive() coercion order, for some operators coercion order was reversed * Fixed 'with' statement in strict mode (did not throw SyntaxError) * Fixed strictness handling of an indirect eval call from a strict function (eval incorrectly inherited strict mode) * Several test262 and underscore.js test case fixes (other than above) * Windows compatibility for both WIN32 and WIN64, tested with MinGW (x86), MINGW-w64 (x64), VS2010 Express (x32), VS2013 Express (x32 and x64) * Portability fixes for non-C99 platforms (like MSVC in VS2010) * Drop 'full distributable' build, which is replaced by the public GitHub repo; simplify Makefiles etc accordingly (this change is not visible in the source distributable) Planned ======= 0.10.0 (2014-03-XX) ------------------- * Avoid "out of regs" for large expressions containing function calls by using indirect call opcodes in bytecode * Add duk_push_heap_stash(), duk_push_global_stash(), and duk_push_thread_stash() to provide C code with stashes for storing values invisible to Ecmascript code * Add Duktape.compact() and Duktape.line() * Add a barebones built-in logging framework with both Ecmascript and C APIs and easy customization * Add a message argument to fatal handler function callback, simplify internal fatal error and panic handling * Compact function templates and instances to reduce memory footprint * Execute finalizers for all objects, even reachable ones, when a heap is freed to allow native resources to be freed reliably * "new Object()" now promotes plain buffer and pointer values to Buffer and Pointer objects * Change Array.prototype.splice() behavior so that if 2nd argument (deleteCount) is not given, splice to end of array instead of treating like deleteCount was zero: the new behavior is non-standard but is the real world behavior used by V8, Rhino, Spidermonkey, etc * Add an automatic 'length' property to Duktape/C functions * Add a feature define to provide a 'caller' property for non-strict functions, with behavior similar to the (non-standard) behavior in e.g. V8 and Rhino * C typing wrapped throughout to allow porting to more exotic platforms, e.g. platforms where "int" is a 16-bit type **FIXME: under work** * Improve self tests to include byte order validation * Allow the global eval() function to be called from C code (causes an indirect eval); this was at least an issue with a bound eval() call * Fix O(depth^2) inner function parsing issue, inner functions are now only parsed once and deeply nested inner functions are no longer a performance issue * On platforms requiring a specific alignment, use an alternate object property table memory layout to reduce memory footprint * Fix a regexp bug: non-capturing groups inside quantifier expressions were matched incorrectly * Fix a regexp bug: capture groups were not reset to 'undefined' when a quantified with capture groups was re-matched by a quantifier * Portability fixes for Crossbridge (Flash), NetBSD (endianness detection and a few Math.pow() fixes), OpenBSD (endianness detection), QNX (endianness and other fixes) * Warning fixes for non-default feature options and a few exotic compilers * Duktape can now be compiled with Emscripten and executed with e.g. V8, "Dukweb" provides an example where Duktape runs on a web page, with Duktape and the browser Javascript environment interacting 0.11.0 (2014-XX-XX) ------------------- 1.0.0 (2014-XX-XX) ------------------- * Feature complete baseline release 1.1.0 (2014-XX-XX) ------------------ * Debugger 2.0.0 (XXXX-XX-XX) ------------------ * Ecmascript 6 features will be implemented in v2.x.x at the earliest (some individual features may be cherry picked into v1.x.x)
