+ **Bug fixes**
* Fix various dead locks in the IOEvents poller.
* Implement LinuxSemaphore class in order to replace buggy POSIX semaphores
on Linux.
* Honor the cmsd.dfs directive for locate request to avoid placing a
file in ENOENT status.
* Make sure that the old client runs only in IPv4 mode as mixing modes does
not work for a variety of reasons.
* Accept old-style as well as new-style IPv6 addresses in the sss
protocol. This allows the new client to use this protocol after
it implemented IPv6 support.
* Prevent invalid mutex operations in auto-termination routine.
* Resolve naming conflicts within the frm that resulted from the
statlib plugin implementation.
* Do not rely in file locking to serialize inter-thread access. This
fixes the prolem of usage file drift.
* Fix various parse context issues in copy config with --recursive.
* Recognize object deletion in the error handling path.
* Use atomic FD_CLOEXEC where available to prevent FD leaks.
* Squelch casting complaints from C++11.

* Propagate info about partial success from deeplocate to dirlist.
* Remove perl interface.
* Send timezone, country code and application name while logging in.

(sdv) calc with reporting sum of squares (ssq) counts.
* Make public headers compile cleanly with -Wall -Wextra -Werror.
* Support passing cert, key paths via URLs
* Allow testing of undefined set/env vars via if-else-fi

-------------
Version 3.3.2
-------------
+ **Major bug fixes**
* Fix the opaque information setting in xrdcp using -OD (issue #1)
* Fix compilation on Solaris 11 (issue #7)
* Fix issues with semaphore locking during thread cancelation on
MaxOSX (issue #10)
* Solve locking problems in the built-in poller (issue #4)
* Solve performance issues in the new client. Note: this actually
changes some low level public interfaces, so the soname of
libXrdCl.so has been bumped to libXrdCl.so.1. The xrootd.org
RPMs also provide the old libXrdCl.so.0 in order to preserve the
binary compatibility with the clients linked against it.
-------------
Version 3.3.1
-------------
+ **Major bug fixes**
* Correct XrdClient ABI incompatibility issue introduced in 3.3.0
* Install additional private headers
-------------
Version 3.3.0
-------------
+ **New Features**
* Stable interfaces immutable in minor releases (except XrdCl). Only
public header files are installed in the usual include directory.
In order to ease up transition of some clients some of the private
include files are also installed in private subdirectory.
* New asynchronous and thread-safe client libraries and executables
(XrdCl). The ABI compatibility is not guaranteed until 4.0.0.
* Build the xrootd protocol plugin as a shared library.
* Add the altds directive to allow pairing a cmsd with an alternate data
server.
* Differentiate between packed and unpacked readv monitoring records.
* Allow plugin libraries to be preloaded. This feature is only meant
for MacOS.
* Include optional site name in summary monitoring records.
* Include optional site name in server identification record if the
site name was specified on the command line (-S) or via config
file (all.sitename directive).
* Define a standard supported mechanism to obtain the default storage
system object.
* Provide an ABI-compatible interface to obtain a default cmsd client
object. This patch does not change the definition of the XrdCmsClient
object and is ABI compatible with all previous releases (DPM support).
* Allow multiple comma separated protocols in XrdSecPROTOCOL client-side
envar. This allows the client to select 1 of n protocols.
* Implement new "f" stream monitoring.
* Add new summary counters for readv and readv segs.
* Add boiler plate comments indicating the all software is licensed under
LGPL. No functional source code was modified by this patch.
* Add GPL and LGPL license text.
* Liberlize locking structure to prevent lock inversion relative to
external locks.
* Provide libevent replacement for Linux (epoll), Solaris (poll_create),
and others (poll). Note: versions of Solaris less than 10 are no longer
supported and they will no longer compile with this update!
* Provide a libevent type replacement package.
* Allow tracker files (e.g. ".fail") to be placed in a shadow directory.
This is controlled by the new fdir option on the oss.xfr directive.
* Allow meta-files (i.e. .fail file) to be relocated to a shadow directory
using the oss.xfr directive. This avoids polluting the exported name
space when an frm transfer operation fails.
* Create a general place for platform dependent utility methods.
* Add third party copy statistics to the summary record.
* zlib compatible checksum plugin
+ **Major bug fixes**
* Serialize access to cache entries to prevent SEGV's.
* Fix the fast response queue so that it doesn't run out of response
slots causing a big performance penalty. This is a high priority fix.
* Properly disarm the mutex helper when the mustex object is deleted.
* Use correct variable to hold osslib parameters. This patch fixes commit
2e27f87a (version checking) and without this patch makes it impossible
to load an oss plug-in.
* Properly check for errors when client read returns 0 and reflect true
status. This only affects the Posix client interface.
* Remove redundant flag indicating a running poller. This may cause the
poller to never be woken up when a timeout value changes.
* Fix <exp> tag in ofs statistics. It is improperly terminated and may
cause certain xml parsers to fail; rendering monitoring useless.
* Undo the side-effect of commit ff8bdbd6 that prevented the frm from
sending stage notifications to xrootd; causing opens and xrdstagetool
to hang with dynamic staging enabled.
* Make sure the id buffer is large enough to hold all id combinations.
* Avoid deadlock when closing a Posix File with an active preread.
* For concurrent queries for the same file allow servers to respond to the
query and only redirect clients to a stageable server if the file is not found.
+ **Minor bug fixes**
* Add EPOLLRDHUP to avoid leaving sockets in CLOSE_WAIT with a one-shot
poll framework.
* Fully integrate checksum processing into a manager node. When configured,
it does not matter whether a client directs a checksum request to a manager
or a server. This also fixes bug report #93388.
* Make sure to reflect proper range of errors during read/write operations.
This also provides filesystem plugins full range of allowed return codes.
