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 InterestFilter abstraction that supports filtering based on name prefixes
            and regular expressions.
        -   Separated Face::registerPrefix() and Face::setInterestFilter() methods allow
            distinct operations of registering with the local NDN forwarder and setting up
            application-specific OnInterest call dispatch using InterestFilters.
-   Security
    -   Add type dir trust-anchor in ValidatorConfig to add all certificates under the
        specified directory as trust anchors. The new option also allows periodic
        reloading trust anchors, allowing dynamic trust models.
    -   Added support for multiple signature types to PublicKey, SecPublicInfo
        abstractions
    -   New SignatureSha256WithEcdsa signature type
-   Wire encoding
    -   Data::getFullName() method to get Data packet name with implicit digest
    -   New Name::getSuccessor() method to get name successor
-   Management
    -   Support for ChannelStatus, StrategyChoice datasets
-   Build
    -   enabled support of precompiled headers for clang and gcc compilers to speed up
        compilation

Updates and bug fixes:

-   Wire encoding
    -   Nonce field is now encoded as 4-byte uint8_t value, as defined by NDN-TLV spec.
    -   Optimized Data packet signing

        KeyChain::sign method now pre-allocates EncodingBuffer, requests unsigned portion
        of Data using Data::wireEncode(EncodingBuffer, true), and then appends the
        resulting signature and prepends Data packet header. This way there is no extra
        memory allocation after Data packet is signed.

-   Security
    -   Allow user to explicitly specify the cert name prefix before 'KEY' component in
        ndnsec-certgen
    -   SignatureSha256 has been renamed to DigestSha256 to conform with NDN-TLV
        specification.
    -   Add checking of Timestamp and Nonce fields in signed Interest within
        ValidatorConfig
    -   Allow validator customization using hooks:

        Sub-classes of Validator class can use the following hooks to fine-tune the
        validation process:

          -   Validator::preCertificateValidation to process
              received certificate before validation.
          -   Validator::onTimeout to process interest timeout
          -   Validator::afterCheckPolicy to process validation
              requests.

-   Other minor fixes and corrections

Deprecated:

-   SignatureSha256 class, use DigestSha256 instead.
-   All Face constructors that accept shared_ptr<io_service>.

    Use versions that accept reference to io_service object.

-   Face::ioService method, use Face::getIoService instead.
-   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 name::Component::toUri instead.
-   SecPublicInfo::addPublicKey method, use SecPublicInfo::addKey instead.
-   Tlv::ConentType constant (typo), use Tlv::ContentType 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 Scheduler.

    In applications, periodic events should be just re-scheduled within the callback for
    single-shot events.
