This has been a long time coming as the last release has been +made over 5 months ago! + +This release includes some changes which affect backwards compatibility, +one major change is that now the hash table ``[]`` operators now raise a +``KeyError`` exception when the key does not exist. + +Some of the more exciting new features include: the ability to unpack tuples +in any assignment context, the introduction of `NimScript <docs/nims.html>`_, +and improvements to the type inference of lambdas. + +There are of course many many many bug fixes included with this release. +We are getting closer and closer to a 1.0 release and are hoping that only +a few 0.x releases will be necessary before we are happy to release version 1.0. + +As always you can download the latest version of Nim from the +`downloads <downloads.html>`_ page. + +For a more detailed list of changes look below. Some of the upcoming breaking +changes are also documented in this forum +`thread <http://forum.nim-lang.org/t/1708>`_. + +Changes affecting backwards compatibility +----------------------------------------- +- ``tables.[]``, ``strtabs.[]``, ``critbits.[]`` **now raise** + the ``KeyError`` **exception when the key does not exist**! Use the + new ``getOrDefault`` instead to get the old behaviour. Compile all your + code with ``-d:nimTableGet`` to get a listing of where your code + uses ``[]``! +- The ``rawsockets`` module has been renamed to ``nativesockets`` to avoid + confusion with TCP/IP raw sockets, so ``newNativeSocket`` should be used + instead of ``newRawSocket``. +- The ``miliseconds`` property of ``times.TimeInterval`` is now ``milliseconds``. + Code accessing that property is deprecated and code using ``miliseconds`` + during object initialization or as a named parameter of ``initInterval()`` + will need to be updated. +- ``std.logging`` functions no longer do formatting and semantically treat + their arguments just like ``echo`` does. Affected functions: ``log``, + ``debug``, ``info``, ``warn``, ``error``, ``fatal``. Custom subtypes of + ``Logger`` also need to be adjusted accordingly. +- Floating point numbers can now look like ``2d`` (float64) + and ``2f`` (float32) which means imports like ``import scene/2d/sprite`` + do not work anymore. Instead quotes have to be + used: ``import "scene/2d/sprite"``. The former code never was valid Nim. +- The Windows API wrapper (``windows.nim``) is now not part of the official + distribution anymore. Instead use the ``oldwinapi`` Nimble package. +- There is now a clear distinction between ``--os:standalone`` + and ``--gc:none``. So if you use ``--os:standalone`` ensure you also use + ``--gc:none``. ``--os:standalone`` without ``--gc:none`` is now a version + that doesn't depend on any OS but includes the GC. However this version + is currently untested! +- All procedures which construct a ``Socket``/``AsyncSocket`` now need to + specify the socket domain, type and protocol. The param name + ``typ: SockType`` (in ``newSocket``/``newAsyncSocket`` procs) was also + renamed to ``sockType``. The param ``af`` in the ``connect`` procs was + removed. This affects ``asyncnet``, ``asyncdispatch``, ``net``, and + ``rawsockets``. +- ``varargs[typed]`` and ``varargs[untyped]`` have been refined and now work + as expected. However ``varargs[untyped]`` is not an alias anymore for + ``varargs[expr]``. So if your code breaks for ``varargs[untyped]``, use + ``varargs[expr]`` instead. The same applies to ``varargs[typed]`` vs + ``varargs[stmt]``. +- ``sequtils.delete`` doesn't take confusing default arguments anymore. +- ``system.free`` was an error-prone alias to ``system.dealloc`` and has + been removed. +- ``macros.high`` never worked and the manual says ``high`` cannot be + overloaded, so we removed it with no deprecation cycle. +- To use the ``parallel`` statement you now have to + use the ``--experimental`` mode. +- Toplevel procs of calling convention ``closure`` never worked reliably + and are now deprecated and will be removed from the language. Instead you + have to insert type conversions + like ``(proc (a, b: int) {.closure.})(myToplevelProc)`` if necessary. +- The modules ``libffi``, ``sdl``, ``windows``, ``zipfiles``, ``libzip``, + ``zlib``, ``zzip``, ``dialogs``, ``expat``, ``graphics``, ``libcurl``, + ``sphinx`` have been moved out of the stdlib and are Nimble packages now. +- The constant fights between 32 and 64 bit DLLs on Windows have been put to + an end: The standard distribution now ships with 32 and 64 bit versions + of all the DLLs the standard library needs. This means that the following + DLLs are now split into 32 and 64 versions: + + * ``pcre.dll``: Split into ``pcre32.dll`` and ``pcre64.dll``. + * ``pdcurses.dll``: Split into ``pdcurses32.dll`` and ``pdcurses64.dll``. + * ``sqlite3.dll``: Split into ``sqlite3_32.dll`` and ``sqlite3_64.dll``. + * ``ssleay32.dll``: Split into ``ssleay32.dll`` and ``ssleay64.dll``. + * ``libeay32.dll``: Split into ``libeay32.dll`` and ``libeay64.dll``. + + Compile with ``-d:nimOldDLLs`` to make the stdlib use the old DLL names. +- Nim VM now treats objects as ``nkObjConstr`` nodes, and not ``nkPar`` nodes + as it was previously. Macros that generate ``nkPar`` nodes when object is + expected are likely to break. Macros that expect ``nkPar`` nodes to which + objects are passed are likely to break as well. +- Base methods now need to be annotated with the ``base`` pragma. This makes + multi methods less error-prone to use with the effect system. +- Nim's parser directive ``#!`` is now ``#?`` in order to produce no conflicts + with Unix's ``#!``. +- An implicit return type for an iterator is now deprecated. Use ``auto`` if + you want more type inference. +- The type ``auto`` is now a "multi-bind" metatype, so the following compiles: + + .. code-block:: nim + proc f(x, y: auto): auto = + result = $x & y + + echo f(0, "abc") +- The ``ftpclient`` module is now deprecated in favour of the + ``asyncftpclient`` module. +- In sequtils.nim renamed ``repeat`` function to ``cycle`` (concatenating + a sequence by itself the given times), and also introduced ``repeat``, + which repeats an element the given times. +- The function ``map`` is moved to sequtils.nim. The inplace ``map`` version + is renamed to ``apply``. +- The template ``mapIt`` now doesn't require the result's type parameter. + Also the inplace ``mapIt`` is renamed to ``apply``. + +Library Additions +----------------- + +- The nre module has been added, providing a better interface to PCRE than re. +- The ``expandSymlink`` proc has been added to the ``os`` module. +- The ``tailDir`` proc has been added to the ``os`` module. +- Define ``nimPinToCpu`` to make the ``threadpool`` use explicit thread + affinities. This can speed up or slow down the thread pool; it's up to you + to benchmark it. +- ``strutils.formatFloat`` and ``formatBiggestFloat`` do not depend on the C + locale anymore and now take an optional ``decimalSep = '.'`` parameter. +- Added ``unicode.lastRune``, ``unicode.graphemeLen``. + + +Compiler Additions +------------------ + +- The compiler now supports a new configuration system based on + `NimScript <docs/nims.html>`_. +- The compiler finally considers symbol binding rules in templates and + generics for overloaded ``[]``, ``[]=``, ``{}``, ``{}=`` operators + (issue `#2599 <https://github.com/nim-lang/Nim/issues/2599>`_). +- The compiler now supports a `bitsize pragma <docs/manual.html#pragmas-bitsize-pragma>`_ + for constructing bitfields. +- Added a new ``--reportConceptFailures`` switch for better debugging of + concept related type mismatches. This can also be used to debug + ``system.compiles`` failures. + + +Language Additions +------------------ + +- ``system.unsafeAddr`` can be used to access the address of a ``let`` + variable or parameter for C interoperability. Since technically this + makes parameters and ``let`` variables mutable, it is considered even more + unsafe than the ordinary ``addr`` builtin. +- Added ``macros.getImpl`` that can be used to access the implementation of + a routine or a constant. This allows for example for user-defined inlining + of function calls. +- Tuple unpacking finally works in a non-var/let context: ``(x, y) = f()`` + is allowed. Note that this doesn't declare ``x`` and ``y`` variables, for + this ``let (x, y) = f()`` still needs to be used. +- ``when nimvm`` can now be used for compiletime versions of some code + sections. Click `here <docs/manual.html#when-nimvm-statement>`_ for details. +- Usage of the type ``NimNode`` in a proc now implicitly annotates the proc + with ``.compileTime``. This means generics work much better for ``NimNode``. + + +Bugfixes +-------- +- Fixed "Compiler internal error on iterator it(T: typedesc[Base]) called with it(Child), where Child = object of Base" + (`#2662 <https://github.com/Araq/Nim/issues/2662>`_) +- Fixed "repr() misses base object field in 2nd level derived object" + (`#2749 <https://github.com/Araq/Nim/issues/2749>`_) +- Fixed "nimsuggest doesn't work more than once on the non-main file" + (`#2694 <https://github.com/Araq/Nim/issues/2694>`_) +- Fixed "JS Codegen.

This makes - multi methods less error-prone to use with the effect system. - - Nim's parser directive ``#!`` is now ``#?`` in order to produce no conflicts - with Unix's ``#!``. - - An implicit return type for an iterator is now deprecated. Use ``auto`` if - you want more type inference. - - The type ``auto`` is now a "multi-bind" metatype, so the following compiles: - - .. code-block:: nim - proc f(x, y: auto): auto = - result = $x & y - - echo f(0, "abc") - - The ``ftpclient`` module is now deprecated in favour of the - ``asyncftpclient`` module. - - In sequtils.nim renamed ``repeat`` function to ``cycle`` (concatenating - a sequence by itself the given times), and also introduced ``repeat``, - which repeats an element the given times. - - The function ``map`` is moved to sequtils.nim. The inplace ``map`` version - is renamed to ``apply``. - - The template ``mapIt`` now doesn't require the result's type parameter. - Also the inplace ``mapIt`` is renamed to ``apply``. - - Library Additions - ----------------- - - - The nre module has been added, providing a better interface to PCRE than re. - - The ``expandSymlink`` proc has been added to the ``os`` module. - - The ``tailDir`` proc has been added to the ``os`` module. - - Define ``nimPinToCpu`` to make the ``threadpool`` use explicit thread - affinities. This can speed up or slow down the thread pool; it's up to you - to benchmark it. - - ``strutils.formatFloat`` and ``formatBiggestFloat`` do not depend on the C - locale anymore and now take an optional ``decimalSep = '.'`` parameter. - - Added ``unicode.lastRune``, ``unicode.graphemeLen``. - - - Compiler Additions - ------------------ - - - The compiler now supports a new configuration system based on - `NimScript <docs/nims.html>`_. - - The compiler finally considers symbol binding rules in templates and - generics for overloaded ``[]``, ``[]=``, ``{}``, ``{}=`` operators - (issue `#2599 <https://github.com/nim-lang/Nim/issues/2599>`_). - - The compiler now supports a `bitsize pragma <docs/manual.html#pragmas-bitsize-pragma>`_ - for constructing bitfields. - - Added a new ``--reportConceptFailures`` switch for better debugging of - concept related type mismatches. This can also be used to debug - ``system.compiles`` failures. - - - Language Additions - ------------------ - - - ``system.unsafeAddr`` can be used to access the address of a ``let`` - variable or parameter for C interoperability. Since technically this - makes parameters and ``let`` variables mutable, it is considered even more - unsafe than the ordinary ``addr`` builtin. - - Added ``macros.getImpl`` that can be used to access the implementation of - a routine or a constant. This allows for example for user-defined inlining - of function calls. - - Tuple unpacking finally works in a non-var/let context: ``(x, y) = f()`` - is allowed. Note that this doesn't declare ``x`` and ``y`` variables, for - this ``let (x, y) = f()`` still needs to be used. - - ``when nimvm`` can now be used for compiletime versions of some code - sections. Click `here <docs/manual.html#when-nimvm-statement>`_ for details. - - Usage of the type ``NimNode`` in a proc now implicitly annotates the proc - with ``.compileTime``. This means generics work much better for ``NimNode``. - - - Bugfixes - -------- - - Fixed "Compiler internal error on iterator it(T: typedesc[Base]) called with it(Child), where Child = object of Base" - (`#2662 <https://github.com/Araq/Nim/issues/2662>`_) - - Fixed "repr() misses base object field in 2nd level derived object" - (`#2749 <https://github.com/Araq/Nim/issues/2749>`_) - - Fixed "nimsuggest doesn't work more than once on the non-main file" - (`#2694 <https://github.com/Araq/Nim/issues/2694>`_) - - Fixed "JS Codegen.
