+A NOTE ON THE CHANGELOG:
+Starting in early 2011, Tcl source code has been under the management of
+fossil, hosted at http://core.tcl.tk/tcl/ .  Fossil presents a "Timeline"
+view of changes made that is superior in every way to a hand edited log file.
+Because of this, many Tcl developers are now out of the habit of maintaining
+this log file.  You may still find useful things in it, but the Timeline is
+a better first place to look now.

+2013-09-19  Donal Fellows  <dkf@users.sf.net>
+
+	* doc/next.n (METHOD SEARCH ORDER): Bug [3606943]: Corrected
+	description of method search order.

+	Corrected implementation of the core of uuencode handling so that the
+	line length processing is correctly applied.
+	***POTENTIAL INCOMPATIBILITY***
+	Existing code that was using the old versions and working around the
+	limitations will now need to do far less. The -maxlen option now has
+	strict limits on the range of supported lengths; this is a limitation
+	of the format itself.

+
+	* generic/tclOOMethod.c (CloneProcedureMethod): [Bug 3609693]: Strip

+
+	* unix/tclXtNotify.c: Bug [817249]: bring tclXtNotify.c up to date with
+	Tcl_SetNotifier() change.
+
+2013-07-02  Jan Nijtmans  <nijtmans@users.sf.net>
+

+
+2013-06-18  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclEvent.c: Bug [3611974]: InitSubsystems multiple thread
+	issue.
+
+2013-06-17  Jan Nijtmans  <nijtmans@users.sf.net>

+
+2013-06-09  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmdsSZ.c (TclCompileTryCmd): [Bug 779d38b996]:
+	Rewrote the [try] compiler to generate better code in some cases and
+	to behave correctly in others; when an error happens during the
+	processing of an exception-trap clause or a finally clause, the
+	*original* return options are now captured in a -during option, even
+	when fully compiled.
+
+2013-06-05  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclExecute.c (INST_EXPAND_DROP): [Bugs 2835313, 3614226]:
+	New opcode to allow resetting the stack to get rid of an expansion,
+	restoring the stack to a known state in the process.
+	* generic/tclCompile.c, generic/tclCompCmds.c: Adjusted the compilers
+	for [break] and [continue] to get stack cleanup right in the majority
+	of cases.
+	* tests/for.test (for-7.*): Set of tests for these evil cases.
+
+2013-06-04  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* unix/tcl.m4: Eliminate NO_VIZ macro as current zlib uses HAVE_HIDDEN
+	instead. One more last-moment fix for FreeBSD by Pietro Cerutti
+
+2013-06-03  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: fix for perf bug detected by Kieran
+	(https://groups.google.com/forum/?fromgroups#!topic/comp.lang.tcl/vfpI3bc-DkQ),
+	diagnosed by dgp to be a close relative of [Bug 781585], which was
+	fixed by commit	[f46fb50cb3]. This bug was introduced by myself in
+	commit [cbfe055d8c].
+
+2013-06-03  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileBreakCmd, TclCompileContinueCmd):
+	Added code to allow [break] and [continue] to be issued as a jump (in
+	the most common cases) rather than using the more expensive exception
+	processing path in the bytecode engine. [Bug 3614226]: Partial fix for
+	the issues relating to cleaning up the stack when dealing with [break]
+	and [continue].
+
+2013-05-27 Harald Oehlmann  <oehhar@users.sf.net>
+
+	* library/msgcat/msgcat.tcl: [Bug 3036566]: Also get locale from

+	Bumped msgcat version to 1.5.2
+
+2013-05-22  Andreas Kupries  <andreask@activestate.com>
+
+	* tclCompile.c: Removed duplicate const qualifier causing the HP
+	native cc to error out.
+
+2013-05-22  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclUtf.c (TclUtfCasecmp): [Bug 3613609]: Replace problematic
+	uses of strcasecmp with a proper UTF-8-aware version. Affects both
+	[lsearch -nocase] and [lsort -nocase].
+
+2013-05-22  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/file.n: [Bug 3613671]: Added note to portability section on the
+	fact that [file owned] does not produce useful results on Windows.
+
+2013-05-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tclUnixFCmd.c (DefaultTempDir): [Bug 3613567]: Corrected logic
+	for checking return code of access() system call, which was inverted.
+
+2013-05-19  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* unix/tcl.m4:     Fix for FreeBSD, and remove support for older
+	* unix/configure:  FreeBSD versions. Patch by Pietro Cerutti.
+
+2013-05-18  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmdsGR.c: Split tclCompCmds.c again to keep size of
+	code down.
+
+2013-05-16  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclBasic.c: Add panic in order to detect incompatible
+	mingw32 sys/stat.h and sys/time.h headers.
+
+2013-05-13  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* compat/zlib/*: Upgrade to zlib 1.2.8
+
+2013-05-10  Donal K. Fellows  <dkf@users.sf.net>
+
+	Optimizations and general bytecode generation improvements.
+	* generic/tclCompCmds.c (TclCompileAppendCmd, TclCompileLappendCmd):
+	(TclCompileReturnCmd): Make these generate bytecode in more cases.
+	(TclCompileListCmd): Make this able to push a literal when it can.
+	* generic/tclCompile.c (TclSetByteCodeFromAny, PeepholeOptimize):
+	Added checks to see if we can apply some simple cross-command-boundary
+	optimizations, and defined a small number of such optimizations.
+	(TclCompileScript): Added the special ability to compile the list
+	command with expansion ([list {*}blah]) into bytecode that does not
+	call an external command.
+
+2013-05-06  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclStubInit.c: Add support for Cygwin64, which has a 64-bit
+	* generic/tclDecls.h: "long" type. Binary compatibility with win64
+	requires that all stub entries use 32-bit long's, therefore the need
+	for various wrapper functions/macros. For Tcl 9 a better solution is
+	needed, but that cannot be done without introducing binary
+	incompatibility.
+
+2013-04-30  Andreas Kupries  <andreask@activestate.com>
+
+	* library/platform/platform.tcl (::platform::LibcVersion):
+	* library/platform/pkgIndex.tcl: Followup to the 2013-01-30 change.
+	The RE become too restrictive again. SuSe added a timestamp after the
+	version. Loosened up a bit. Bumped package to version 1.0.12.
+
+2013-04-29  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileArraySetCmd): Generate better code
+	when the list of things to set is a literal.
+
+2013-04-25  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclDecls.h: Implement Tcl_NewBooleanObj, Tcl_DbNewBooleanObj
+	and Tcl_SetBooleanObj as macros using Tcl_NewIntObj, Tcl_DbNewLongObj
+	and Tcl_SetIntObj. Starting with Tcl 8.5, this is exactly the same, it
+	only eliminates code duplication.
+	* generic/tclInt.h: Eliminate use of NO_WIDE_TYPE everywhere: It's
+	exactly the same as TCL_WIDE_INT_IS_LONG
+
+2013-04-19  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclDecls.h: Implement many Tcl_*Var* functions and
+	Tcl_GetIndexFromObj as (faster/stack-saving) macros around resp their
+	Tcl_*Var*2 equivalent and Tcl_GetIndexFromObjStruct.
+
+2013-04-12  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* generic/tclDecls.h: Implement Tcl_Pkg* functions as
+	(faster/stack-saving) macros around Tcl_Pkg*Ex functions.
+
+2013-04-08  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/regc_color.c:	[Bug 3610026]: Stop crash when the number of
+	* generic/regerrs.h:	"colors" in a regular expression overflows a
+	* generic/regex.h:	short int.  Thanks to Heikki Linnakangas for
+	* generic/regguts.h:	the report and the patch.
+	* tests/regexp.test:
+
+2013-04-04  Reinhard Max  <max@suse.de>
+
+	* library/http/http.tcl (http::geturl): Allow URLs that don't have a
+	path, but a query query, e.g. http://example.com?foo=bar
+	* Bump the http package to 2.8.7.
+

+.RI [ -exvlo ]
+zipfile [ files_to_extract ] [-d tempdir]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the extraction of compressed file
+archives in the ZIP format used by the MS-DOS utility PKZIP.  It was
+written as a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR unzip (1)
+program.
+.SH OPTIONS
+A number of options are supported.  With the exception of
+.BI \-d\  tempdir
+these must be supplied before any
+other arguments and are:
+.TP
+.BI \-l\ ,\ \-\-v
+List the files in the archive without extracting them.
+.TP
+.B \-o
+Overwrite files without prompting for confirmation.
+.TP
+.B \-x
+Extract files (default).
+.PP
+The
+.I zipfile
+argument is the name of the archive to process. The next argument can be used
+to specify a single file to extract from the archive.
+
+Lastly, the following option can be specified at the end of the command-line:
+.TP
+.BI \-d\  tempdir
+Extract the archive in the directory
+.I tempdir
+rather than the current directory.
+.SH SEE ALSO
+.BR minizip (1),
+.BR zlib (3),
+.BR unzip (1).
+.SH AUTHOR
+This program was written by Gilles Vollant.  This manual page was
+written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
+was added by Dirk Eddelbuettel <edd@debian.org>.

+.SH NAME
+minizip - create ZIP archives
+.SH SYNOPSIS
+.B minizip
+.RI [ -o ]
+zipfile [ " files" ... ]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the creation of compressed file archives
+in the ZIP format used by the MS-DOS utility PKZIP.  It was written as
+a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR zip (1)
+program.
+.SH OPTIONS
+The first argument supplied is the name of the ZIP archive to create or
+.RI -o
+in which case it is ignored and the second argument treated as the
+name of the ZIP file.  If the ZIP file already exists it will be
+overwritten.
+.PP
+Subsequent arguments specify a list of files to place in the ZIP
+archive.  If none are specified then an empty archive will be created.

+The Tcl interpreter that the TclOO API is integrated with and whose C
+interface is going to be used.
+.BE
+.SH DESCRIPTION
+.PP
+When an extension library is going to use the C interface exposed by TclOO, it
+should use \fBTcl_OOInitStubs\fR to initialize its access to that interface
+from within its \fI*\fB_Init\fR (or \fI*\fB_SafeInit\fR) function, passing in
+the \fIinterp\fR that was passed into that routine as context. If the result
+of calling \fBTcl_OOInitStubs\fR is NULL, the initialization failed and an
+error message will have been left in the interpreter's result. Otherwise, the
+initialization succeeded and the TclOO API may thereafter be used; the
+version of the TclOO API is returned.
+.PP
+When using this function, either the C #define symbol \fBUSE_TCLOO_STUBS\fR
+should be defined and your library code linked against the Tcl stub library,
+or that #define symbol should \fInot\fR be defined and your library code
+linked against the Tcl main library directly.
+.SH "BACKWARD COMPATIBILITY NOTE"
+.PP
+If you are linking against the Tcl 8.5 forward compatibility package for
+TclOO, \fIonly\fR the stub-enabled configuration is supported and you should
+also link against the TclOO independent stub library; that library is an
+integrated part of the main Tcl stub library in Tcl 8.6.

+Strings in Tcl are logically a sequence of 16-bit Unicode characters.

+\fBTcl_GetString\fR to ensure that the \fIbytes\fR field is populated.
