This release includes contributions by Daphne Pfister to resynchronize the
X11 color name list with the CSS color name list that has forked from ours,
and also includes a couple minor improvements to the showrgb program and
to the build configuration.
Pegex attempts to be the simplest way to define new (or old) Domain
Specific Languages (DSLs) that need to be used in several programming
languages and environments. Things like JSON, YAML, Markdown etc.
It also great for writing parsers/compilers that only need to work
in one language.
In this version, reading documents has been simplified by the removal
of the page next/previous buttons from the toolbar(!)

This package provides an implementation of the ideas presented in the paper
"Functional Pearl: Implicit Configurations" by Oleg Kiselyov and
Chung-chieh Shan. However, the API has been streamlined to improve
performance.
The original paper can be obtained from
http://www.cs.rutgers.edu/~ccshan/prepose/prepose.pdf.
For a summary of the approach taken by this library, along with more
motivating examples, see Austin Seipp's tutorial at
https://www.fpcomplete.com/user/thoughtpolice/using-reflection.

* New features
- Several SMTP server protocol negotiation improvements.
- Added UTF-8 byte order marks to stunnel.conf templates.
- DH parameters are no longer generated by "make cert".
The hardcoded DH parameters are sufficiently secure,
and modern TLS implementations will use ECDH anyway.
- Updated manual for the "options" configuration file option.
- Added support for systemd 209 or later.
- New --disable-systemd ./configure option.
- setuid/setgid commented out in stunnel.conf-sample.
* Bugfixes
- Added support for UTF-8 byte order mark in stunnel.conf.
- Compilation fix for OpenSSL with disabled SSLv2 or SSLv3.
- Non-blocking mode set on inetd and systemd descriptors.
- shfolder.h replaced with shlobj.h for compatibility
with modern Microsoft compilers.
Version 5.06, 2014.10.15, urgency: HIGH:
* Security bugfixes
- OpenSSL DLLs updated to version 1.0.1j.
https://www.openssl.org/news/secadv_20141015.txt
- The insecure SSLv2 protocol is now disabled by default.
It can be enabled with "options = -NO_SSLv2".
- The insecure SSLv3 protocol is now disabled by default.
It can be enabled with "options = -NO_SSLv3".
- Default sslVersion changed to "all" (also in FIPS mode)
to autonegotiate the highest supported TLS version.
* New features
- Added missing SSL options to match OpenSSL 1.0.1j.
- New "-options" commandline option to display the list
of supported SSL options.
* Bugfixes
- Fixed FORK threading build regression bug.
- Fixed missing periodic Win32 GUI log updates.
Version 5.05, 2014.10.10, urgency: MEDIUM:
* New features
- Asynchronous communication with the GUI thread for faster
logging on Win32.
- systemd socket activation (thx to Mark Theunissen).
- The parameter of "options" can now be prefixed with "-"
to clear an SSL option, for example:
"options = -LEGACY_SERVER_CONNECT".
- Improved "transparent = destination" manual page (thx to
Vadim Penzin).
* Bugfixes
- Fixed POLLIN|POLLHUP condition handling error resulting
in prematurely closed (truncated) connection.
- Fixed a null pointer dereference regression bug in the
"transparent = destination" functionality (thx to
Vadim Penzin). This bug was introduced in stunnel 5.00.
- Fixed startup thread synchronization with Win32 GUI.
- Fixed erroneously closed stdin/stdout/stderr if specified
as the -fd commandline option parameter.
- A number of minor Win32 GUI bugfixes and improvements.
- Merged most of the Windows CE patches (thx to Pierre Delaage).
- Fixed incorrect CreateService() error message on Win32.
- Implemented a workaround for defective Cygwin file
descriptor passing breaking the libwrap support:
http://wiki.osdev.org/Cygwin_Issues#Passing_file_descriptors
Version 5.04, 2014.09.21, urgency: LOW:
* New features
- Support for local mode ("exec" option) on Win32.
- Support for UTF-8 config file and log file.
- Win32 UTF-16 build (thx to Pierre Delaage for support).
- Support for Unicode file names on Win32.
- A more explicit service description provided for the
Windows SCM (thx to Pierre Delaage).
- TCP/IP dependency added for NT service in order to prevent
initialization failure at boot time.
- FIPS canister updated to version 2.0.8 in the Win32 binary
build.
* Bugfixes
- load_icon_default() modified to return copies of default icons
instead of the original resources to prevent the resources
from being destroyed.
- Partially merged Windows CE patches (thx to Pierre Delaage).
- Fixed typos in stunnel.init.in and vc.mak.
- Fixed incorrect memory allocation statistics update in
str_realloc().
- Missing REMOTE_PORT environmental variable is provided to
processes spawned with "exec" on Unix platforms.
- Taskbar icon is no longer disabled for NT service.
- Fixed taskbar icon initialization when commandline options are
specified.
- Reportedly more compatible values used for the dwDesiredAccess
parameter of the CreateFile() function (thx to Pierre Delaage).
- A number of minor Win32 GUI bugfixes and improvements.
For a a list of bugfixes, see http://valgrind.org/docs/manual/dist.news.html.
Other changes are listed below.
3.10.0 is a feature release with many improvements and the usual
collection of bug fixes.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
MIPS64/Linux, ARM/Android, MIPS32/Android, X86/Android, X86/MacOSX 10.9
and AMD64/MacOSX 10.9. Support for MacOSX 10.8 and 10.9 is
significantly improved relative to the 3.9.0 release.
* ================== PLATFORM CHANGES =================
* Support for the 64-bit ARM Architecture (AArch64 ARMv8). This port
is mostly complete, and is usable, but some SIMD instructions are as
yet unsupported.
* Support for little-endian variant of the 64-bit POWER architecture.
* Support for Android on MIPS32.
* Support for 64bit FPU on MIPS32 platforms.
* Both 32- and 64-bit executables are supported on MacOSX 10.8 and 10.9.
* Configuration for and running on Android targets has changed.
See README.android in the source tree for details.
* ================== DEPRECATED FEATURES =================
* --db-attach is now deprecated and will be removed in the next
valgrind feature release. The built-in GDB server capabilities are
superior and should be used instead. Learn more here:
http://valgrind.org/docs/manual/manual-core-adv.html#manual-core-adv.gdbserver
* ==================== TOOL CHANGES ====================
* Memcheck:
- Client code can now selectively disable and re-enable reporting of
invalid address errors in specific ranges using the new client
requests VALGRIND_DISABLE_ADDR_ERROR_REPORTING_IN_RANGE and
VALGRIND_ENABLE_ADDR_ERROR_REPORTING_IN_RANGE.
- Leak checker: there is a new leak check heuristic called
"length64". This is used to detect interior pointers pointing 8
bytes inside a block, on the assumption that the first 8 bytes
holds the value "block size - 8". This is used by
sqlite3MemMalloc, for example.
- Checking of system call parameters: if a syscall parameter
(e.g. bind struct sockaddr, sendmsg struct msghdr, ...) has
several fields not initialised, an error is now reported for each
field. Previously, an error was reported only for the first
uninitialised field.
- Mismatched alloc/free checking: a new flag
--show-mismatched-frees=no|yes [yes] makes it possible to turn off
such checks if necessary.
* Helgrind:
- Improvements to error messages:
o Race condition error message involving heap allocated blocks also
show the thread number that allocated the raced-on block.
o All locks referenced by an error message are now announced.
Previously, some error messages only showed the lock addresses.
o The message indicating where a lock was first observed now also
describes the address/location of the lock.
- Helgrind now understands the Ada task termination rules and
creates a happens-before relationship between a terminated task
and its master. This avoids some false positives and avoids a big
memory leak when a lot of Ada tasks are created and terminated.
The interceptions are only activated with forthcoming releases of
gnatpro >= 7.3.0w-20140611 and gcc >= 5.0.
- A new GDB server monitor command "info locks" giving the list of
locks, their location, and their status.
* Callgrind:
- callgrind_control now supports the --vgdb-prefix argument,
which is needed if valgrind was started with this same argument.
* ==================== OTHER CHANGES ====================
* Unwinding through inlined function calls. Stack unwinding can now
make use of Dwarf3 inlined-unwind information if it is available.
The practical effect is that inlined calls become visible in stack
traces. The suppression matching machinery has been adjusted
accordingly. This is controlled by the new option
--read-inline-info=yes|no. Currently this is enabled by default
only on Linux and Android targets and only for the tools Memcheck,
Helgrind and DRD.
* Valgrind can now read EXIDX unwind information on 32-bit ARM
targets. If an object contains both CFI and EXIDX unwind
information, Valgrind will prefer the CFI over the EXIDX. This
facilitates unwinding through system libraries on arm-android
targets.
* Address description logic has been improved and is now common
between Memcheck and Helgrind, resulting in better address
descriptions for some kinds of error messages.
* Error messages about dubious arguments (eg, to malloc or calloc) are
output like other errors. This means that they can be suppressed
and they have a stack trace.
* The C++ demangler has been updated for better C++11 support.
* New and modified GDB server monitor features:
- Thread local variables/storage (__thread) can now be displayed.
- The GDB server monitor command "v.info location <address>"
displays information about an address. The information produced
depends on the tool and on the options given to valgrind.
Possibly, the following are described: global variables, local
(stack) variables, allocated or freed blocks, ...
- The option "--vgdb-stop-at=event1,event2,..." allows the user to
ask the GDB server to stop at the start of program execution, at
the end of the program execution and on Valgrind internal errors.
- A new monitor command "v.info stats" shows various Valgrind core
and tool statistics.
- A new monitor command "v.set hostvisibility" allows the GDB server
to provide access to Valgrind internal host status/memory.
* A new option "--aspace-minaddr=<address>" can in some situations
allow the use of more memory by decreasing the address above which
Valgrind maps memory. It can also be used to solve address
conflicts with system libraries by increasing the default value.
See user manual for details.
* The amount of memory used by Valgrind to store debug info (unwind
info, line number information and symbol data) has been
significantly reduced, even though Valgrind now reads more
information in order to support unwinding of inlined function calls.
* Dwarf3 handling with --read-var-info=yes has been improved:
- Ada and C struct containing VLAs no longer cause a "bad DIE" error
- Code compiled with
-ffunction-sections -fdata-sections -Wl,--gc-sections
no longer causes assertion failures.
* Improved checking for the --sim-hints= and --kernel-variant=
options. Unknown strings are now detected and reported to the user
as a usage error.
* The semantics of stack start/end boundaries in the valgrind.h
VALGRIND_STACK_REGISTER client request has been clarified and
documented. The convention is that start and end are respectively
the lowest and highest addressable bytes of the stack.
