New in DMD 2.094.2 (Nov 22, 2020)
- 2.094.2 comes with 1 major change and 14 fixed Bugzilla issues. A huge thanks goes to the 10 contributors who made 2.094.2 possible.
- Runtime changes:
- Support time64 changes for CRuntime_Musl
- Up to v1.1.24, Musl used a 32 bits time_t on 32 bits architectures. Since v1.2.0, time_t is now always 64 bits. From this release, druntime will also default to a 64 bits time_t on 32 bits architecture, unless the CRuntime_Musl_Pre_Time64w is provided.
- This change should only affect packagers for Musl-based systems who support 32 bits architectures (64 bits architectures already use 64 bits time_t), who now need to define CRuntime_Musl_Pre_Time64 both when building druntime / Phobos and in the default configuration, if the linked Musl is < 1.2.0.

New in DMD 2.071.0 (Aug 18, 2016)
- Compiler Changes
- Import access checks for fully qualified names were fixed.
- Protection for selective and renamed imports were fixed.
- Language Changes
- Imports no longer hide locals declared in outer scopes.
- Private symbols are no longer visible in other modules.
- Manifest constant can now be used for deprecation message.
- Library Changes
- A clear method has been added to associative arrays to remove all elements.
- The GC now uses a spinlock instead of a recursive mutex.
- Calls to GC.free are now ignored during finalization instead of throwing an InvalidMemoryOperationError, see Bugzilla 15353.
- GC.addRoot and GC.addRange now use a separate lock.
- GCAllocator.goodAllocSize was added.
- High-level API of std.net.curl now uses Appender for received content. Which generally makes all calls slightly faster. Up to 200ms for large amounts of data.
- Repeat was added to obtain a repeating AliasSeq consisting of template arguments.
- fold was added as an alternative to reduce with argument order swapped.
- Added nextPow2 and truncPow2 to std.math.
- bsf, bsr, and popcnt now work with ulongs on 32 bit systems.
- topN is now 5% - 7% faster.
- Unary overloads of startsWith and endsWith were added.
- maxCount and maxPos were added.
- Range support for the convenience wrapper redBlackTree was added.
- List of all bug fixes and enhancements in D 2.071.0.
- Compiler Changes
- Import access checks for fully qualified names were fixed.
- It is no longer possible to bypass private imports by using fully qualified names, e.g. the following example will fail with package std.range is not accessible here.
- import std.algorithm;
- static assert(std.range.isForwardRange!string);
- To ease updating existing code, the old behavior was retained but deprecated.
- Protection for selective and renamed imports were fixed.
- It is no longer possible to use private selective or renamed imports in another module, e.g. the following example will fail with a.File is not visible from module b.
- module a;
- import std.stdio : File; // imports are private by default
- module b;
- import a;
- File f; // File is private
- To ease updating existing code, the old behavior was retained but deprecated. This fix relies on the visibility changes introduced with DIP22.
- Language Changes
- Imports no longer hide locals declared in outer scopes.
- These changes were made to the name lookup algorithm:
- Lookup for unqualified names is change from one pass to two pass. The first pass goes through the scopes but does not check import declarations. If not found, the second pass goes through the scopes and only looks at import declarations.
- Qualified name lookups, base class lookups, and WithStatement lookups no longer search import declarations, unless a module is the subject of the lookup, where the behavior remains as before.
- This can break existing code, although reliance on the previous behavior tends to be unintended, and fixing it improves the comprehensibility of the code. Breakage tends to take the form of a symbol now being flagged as undefined. Fixing the breakage can be done by fully qualifying the name, or adding an alias to the import declaration.
- The old lookup behavior can be restored using the -transition=import compiler switch. With -transition=checkimports the compiler will issue deprecation warnings when the old and new lookup find different symbols. You can combine both switches to use the old lookup and still get deprecation warnings.
- See also Bugzilla 10378
- Private symbols are no longer visible in other modules.
- Protection (private, package, protected) is now already enforced during symbol lookup in order to resolve any conflicts between private and public symbols that could occur with the old access check scheme.
- The visibility of overloaded symbols with mixed protection is determined by the most visibile member, but additional access check against the exact symbol is performed after overload resolution.
- To ease updating existing code, a deprecated search for invisible symbols will be performed. For the the old lookup behavior (using the -transition=import or -transition=checkimports compiler switch) symbol visibility is ignored. All existing access checks remain active during the deprecation phase.
- See also DIP22
- Manifest constant can now be used for deprecation message.
- Manifest constants (enum, static immutable) can now be used for deprecation message, as well as concatenated strings.
- Example:
- string generateMessage() { return "Some deprecation message"; }
- enum DepMsg = generateMessage();
- deprecated(DepMsg) class Foo {}
- deprecated("Some long deprecation " ~ "message") class Bar {}
- Library Changes
- A clear method has been added to associative arrays to remove all elements.
- One can now use aa.clear() to remove all elements from an associative array. This allows removing all elements from all references to the same array (setting to null just reset the reference, but did not removed the elements from other references).
- auto aa = ["first" : "entry", "second": "entry"];
- auto aa2 = aa1; // reference to the same AA
- aa.clear(); // still retains its current capacity for faster imports
- assert(aa2.length == 0); // other references affected
- The GC is no longer wrapped in a pthread_mutex, it now uses a spinlock.
- This results in a 5% faster GC on average, with the most benefits going to multi-threaded programs that use the GC. See druntime#1447 for more details.
- Added nextPow2 and truncPow2 to std.math.
- nextPow2 and truncPow2 are functions for rounding numbers to powers of two.
- import std.math;
- assert(nextPow2(10) == 16);
- assert(nextPow2(4000) == 4096);
- assert(truncPow2(10) == 8);
- assert(truncPow2(4000) == 2048);
- Unary overloads of startsWith and endsWith were added.
- startsWith and endsWith can now be used just with a predicate.
- import std.algorithm.searching;
- import std.ascii : isAlpha;
- assert("abc".endsWith!isAlpha);
- assert(!"ab1".endsWith!(a => a.isAlpha));
- assert("abc".startsWith!isAlpha);
- assert(!"1ab".startsWith!isAlpha);
- maxCount and maxPos were added.
- Previous to this addition, in order to get the number of the greatest elements, you had to use minCount!"a > b", which was very confusing. This change adds convenience functions to fix this issue.

New in DMD 2.070.0 (Aug 18, 2016)
- Language Changes
- Add syntactic support to make an alias to a function literal.
- Library Changes
- The package std.experimental.ndslice was added. It is also available as part of the Mir library.
- The core.sys.windows package has been greatly expanded.
- TypeInfo.init has been renamed to TypeInfo.initializer.
- std.json encodes string control characters.
- Default LogLevel of FileLogger was changed to LogLevel.all.
- Access to the internal ptr and len fields of BitArray was deprecated.
- List of all bug fixes and enhancements in D 2.070.0.
- Language Changes
- Add syntactic support to make an alias to a function literal.
- Example:
- alias less1 = (a, b) => a < b;
- alias less2 = (a, b) => a > b;
- import std.algorithm : sort, equal;
- int[] arr = [4, 1, 3, 2];
- assert(equal(sort!less1(arr), [1, 2, 3, 4]));
- assert(equal(sort!less2(arr), [4, 3, 2, 1]));
- Library Changes
- The core.sys.windows package has been greatly expanded.
- The core.sys.windows package now contains a considerably more comprehensive set of Windows API bindings. The package has been adapted from Stewart Gordon's bindings, which were originally adapted from the MinGW project.
- TypeInfo.init has been renamed to TypeInfo.initializer.
- The method TypeInfo.init has been renamed to TypeInfo.initializer to resolve a name clash with the type property init.
- An alias with the old name was added and will be deprecated over the next releases.
- std.json encodes string control characters.
- Instead of throwing a JSONException, toJSON encodes now the control characters of a string.
- assert(toJSON(JSONValue("foou007fbar")) == `"foou007Fbar"`);
