+    Add unit declarator to module declarations
+
+    As of Rakudo 2015.05, the `unit` declarator is required before using
+    `module`, `class` or `grammar` declarations (unless it uses a block).  Code
+    still using the old blockless semicolon form will throw a warning. This
+    commit stops the warning from appearing in the new Rakudo.

-    Squashed 'ext/File__Find/' changes from a2e1797..119e620
+    Unlink destination before performing copy on non-Windows
+
+    MoarVM uses mmap() to map bytecode files into memory.  Unfortunately,
+    this means that if a process overwrites the contents of that bytecode
+    file during the operation of a Perl 6 program using it (for example,
+    Panda updating its own dependencies), the memory map will seemingly
+    change out from under MoarVM, usually resulting in a crash.  Unlinking
+    the destination first doesn't harm processes that have loaded that
+    bytecode; it just guarantees that the new version gets its own inode
+    and doesn't mess with currently running Perl 6 processes.

-    a287c19 Merge github.com:tadzik/File-Find
-    23c3b96 module to unit module
+    Note that this is non-atomic, so a Perl 6 process started at just
+    the wrong time will try to open the bytecode file between the unlinking
+    and the creation of the copy, or worse yet, open and use the file
+    while it's being written.  The risk of this is low enough where this
+    shouldn't be a problem, and could easily be mitigated in the future
+    using rename().

+    This change doesn't happen for Windows, mainly because I don't know
+    how Windows responds to files being removed while other processes have
+    them open.  jnthn tells me this will result in an access violation,
+    so a Windows-specific fix is still necessary.  However, perhaps no
+    fix is necessary on Windows at all.
