++++++++++++++++++++++++++++++++++++++++++++
Release date: August 25, 2014
New features:
^^^^^^^^^^^^^
- **Base**
+ The license under which the library is released is changed to **Lesser GNU Public
License version 3.0**.
+ New ways to use incoming Interest dispatching:
* New :ndn-cxx:`InterestFilter` abstraction that supports filtering based on name
prefixes and regular expressions.
* Separated :ndn-cxx:`Face::registerPrefix()` and :ndn-cxx:`Face::setInterestFilter()`
methods allow distinct operations of registering with the local NDN forwarder and setting
up application-specific ``OnInterest`` call dispatch using InterestFilters.
+ Add support for new `NDN naming conventions
<http://named-data.net/doc/tech-memos/naming-conventions.pdf>`_ (:issue:`1761`)
- **Security**
+ Add ``type dir`` :ref:`trust-anchor in ValidatorConfig <validator-conf-trust-anchors>`
to add all certificates under the specified directory as trust anchors.
The new option also allow periodic reloading trust anchors, allowing dynamic trust
models.
+ Added support for multiple signature types to :ndn-cxx:`PublicKey`,
:ndn-cxx:`SecPublicInfo` abstractions
+ New :ndn-cxx:`SignatureSha256WithEcdsa` signature type
+ Updates in :ndn-cxx:`Signature` data structure to reflect changes in `NDN-TLV spec
0.1.1 <http://named-data.net/doc/NDN-TLV/0.1.1/>`_
- **Wire encoding**
+ :ndn-cxx:`Data::getFullName() <getFullName()>` method to get :ndn-cxx:`Data` packet
name with implicit digest

:ndn-cxx:`KeyChain::sign` method now pre-allocates :ndn-cxx:`EncodingBuffer`, requests
unsigned portion of :ndn-cxx:`Data` using ``Data::wireEncode(EncodingBuffer, true)``,
and then appends the resulting signature and prepends :ndn-cxx:`Data` packet header.
This way there is no extra memory allocation after :ndn-cxx:`Data` packet is signed.
+ Optimized implicit digest calculation in :ndn-cxx:`Interest::matchesData` method
(:issue:`1769`)

`NDN-TLV specification <http://named-data.net/doc/ndn-tlv/>`_.
+ Add checking of ``Timestamp`` and ``Nonce`` fields in signed Interest within
:ndn-cxx:`ValidatorConfig`
+ Allow validator customization using hooks:
Sub-classes of :ndn-cxx:`Validator` class can use the following hooks to fine-tune the
validation process:
* :ndn-cxx:`Validator::preCertificateValidation <preCertificateValidation>` to
process received certificate before validation.
* :ndn-cxx:`Validator::onTimeout <onTimeout>` to process interest timeout
* :ndn-cxx:`Validator::afterCheckPolicy <afterCheckPolicy>` to process validation requests.
+ Fix memory issues in :ndn-cxx:`SecPublicInfoSqlite3`
- **Miscellaneous tools**
+ Redefine method for random number generation: ``random::generateWord*`` and
``random::generateSecureWord*`` to generate cryptographically non-secure (fast) and
secure (slow) random numbers.
- Other minor fixes and corrections
Deprecated:
^^^^^^^^^^^
- ``SignatureSha256`` class, use :ndn-cxx:`DigestSha256` instead.
- All :ndn-cxx:`Face` constructors that accept ``shared_ptr<io_service>``.
Use versions that accept reference to ``io_service`` object.
- ``Face::ioService`` method, use :ndn-cxx:`Face::getIoService` instead.
- :ndn-cxx:`Interest` constructor that accepts name, individual selectors, and individual
guiders as constructor parameters.
Use ``Interest().setX(...).setY(...)`` or use the overload taking ``Selectors``
- ``name::Component::toEscapedString`` method, use :ndn-cxx:`name::Component::toUri` instead.
- ``SecPublicInfo::addPublicKey`` method, use :ndn-cxx:`SecPublicInfo::addKey` instead.
- ``Tlv::ConentType`` constant (typo), use ``Tlv::ContentType`` instead.
- ``CommandInterestGenerator`` and ``CommandInterestValidator`` utility classes.
:ndn-cxx:`ValidatorConfig` should be used instead.
Removed:
^^^^^^^^
- support of ndnd-tlv (only NFD management protocol is supported now)
- ``SecPublicInfoMemory`` and ``SecTpmMemory`` classes that were no longer used
- Removing concept of periodic event from :ndn-cxx:`Scheduler`.
In applications, periodic events should be just re-scheduled within the callback for
single-shot events.

ndn-cxx v0.1.0
++++++++++++++
Release date: May 7, 2014
Version 0.1.0 is the initial release of ndn-cxx, an NDN C++ library with eXperimental
eXtensions.
Originally based on `ndn-cpp library <https://github.com/named-data/ndn-cpp>`_ the ndn-cxx
library adopts a slightly different design philosophy (including an extensive use of Boost
libraries to facilitate development, as well as the use of Crypto++ library to support
cryptographic operations), and includes a number of extensions that aim to simplify NDN
application development.
The current features include:
- **Base**
+ Fully asynchronous, event-driven communication model, which is implemented using `Boost.Asio
<http://www.boost.org/doc/libs/1_48_0/doc/html/boost_asio.html>`_
+ Single-threaded, but thread-safe Face operations
A single Face object can be safely used in multiple threads to express Interests and
publish Data packets
+ Explicit time management for NDN operations using `Boost.Chrono
<http://www.boost.org/doc/libs/1_48_0/doc/html/chrono.html>`_
+ Simplified and extended `NDN API <doxygen/annotated.html>`_
+ Extensive set of unit-tests based on `Boost.Test framework
<http://www.boost.org/doc/libs/1_48_0/libs/test/doc/html/index.html>`_
- Continuous integration using an in-house installation of Jenkins build bots and the
hosted `Travis CI <https://travis-ci.org/named-data/ndn-cxx>`_ continuous
integration service compile and verify correctness of the library for each commit
- **Wire format**
+ Full support of `NDN-TLV packet format v0.1 <http://named-data.net/doc/NDN-TLV/0.1/>`_
+ Pure C++ implementation of wire encoding/decoding with simple access to wire format
of all NDN packet abstractions via ``wireEncode`` and ``wireDecode`` methods
In many cases, NDN packet abstractions are just "indices" to the wire format
- **Communication with the forwarder**
+ Enable connecting to local forwarder via UNIX and TCP transports and to remote
forwarders using TCP transport
+ Full support for communication with `Named Data Networking Forwarding Daemon (NFD)
<https://github.com/named-data/NFD>`_
- Full support for `NFD management protocols
<http://redmine.named-data.net/projects/nfd/wiki/Management>`_ to NFD status
information, create and manage NFD Faces, receive NFD Face status change
notifications, update StrategyChoice for namespaces, and manage routes in RIB
- Support for `LocalControlHeader
<http://redmine.named-data.net/projects/nfd/wiki/LocalControlHeader>`_ to implement
special NDN applications that need low-level control of NDN packet forwarding
- **Security support**
+ A set of security primitives to allowing implementation of secure NDN applications in
a simplified manner
- **KeyChain**: provides simple interfaces of packet signing, and key and certificate
management
- **ValidatorConfig**: validator that implements trust model defined in a configuration
file
- **CommandInterestGenerator** and **CommandInterestValidator**: convenient helpers to produce
and validate command interests, while preventing potential replay attacks
+ Several implementations of trusted platform modules to securely manage private keys
- **SecTpmOsx**: TPM based on OSX KeyChain (OSX-specific)
- **SecTpmFile**: TPM that uses file-based access control to protect keys (cross-platform)
+ Extensive set of security command-line tools to manage security identities and certificates
- Generating private/public keys
- Issuing certificates
- Exporting/importing identities
- Managing default security settings
- **Miscellaneous tools**
+ Scheduler to support delayed time operations
+ NDN regular expressions
+ Simple config file to alter various aspects of the library
+ **tlvdump**: a simple tool to visualize TLV-encoded blocks
