standard methods such as copy(), added interfaces for
specifying thresholds, reduced default spreading gain.
filter
* firinterp: added flush() method to run zeros through filter.
* rresamp: allow for default bandwidth with an input of -1.

- Update to latest tagged release version 1.6.0
* build
- increased code coverage to 85% globally across entire
project. This is the single largest effort included in this
version and touches most modules in some way, most particularly
the framing objects cleaning build to remove compiler warnings
(e.g. unused variables) stripped version number off archive
* dotprod
- added support for AVX512-F (thanks, @vankxr!)
* framing
- added numerous tests to increase coverage to 84%
- framesync64: using new qdsync object for simplified operation
- qdsync: new frame detector and synchronizer to much more
easily support frame processing. The object not only
detects the frame, but also provides an initial carrier
frequency, phase, and timign offset, and also corrects for
these impairments, passing the results to the user in a clean
callback function.
* modem
- cpfskmod: increasing phase stability for long runs
* multichannel
- added numerous tests to increase coverage to 88%
* optim
- added numerous tests to increase coverage to 92%
* sequence
- msequence: extended support for state variables up to m=31,
reversed order for generator polynomial and internal state
definition to be more consistent with literature and
readily-available genpolys
- Update to release version 1.5.0

- Update to release version 1.5.0
* build
- added support for PlatformIO for embeedded development
- incorporated recursive copy() methods to objects to facilitate
c++ copy constructors for bindings; now all objects can be
deep copied to a new object with their entire memory and state
preserved
- added convenience method to malloc and copy memory arrays
- improved support for error codes across objects and methods
- cleaned up spelling errors across project (thanks, @nowls!)
scrubbed function argument variable names to avoid underscore
followed by a capital letter, causing trouble with pre-compiler
processing
- added basic test to check linking to installed library,
incorporating into CI/CD pipelines
- added more example programs
* autotest
- increased coverage testing (81% across entire project)
- added the ability to "hammer" a particular test by running
repeatedly on incremental seeds to assess specific edge cases
(e.g. with random data)
- added timer to show execution time for each test and identify
areas for speed improvements
- added methods for testing spectral response of various fields
- added special directory for storing output logs: autotest/logs/
* benchmark
- replacing old C-based benchmark comparison with simpler python
version
* dotprod
- added support for AVX SIMD in vector dot products (thanks, @vankxr!)
* fft
- adding macro to allow for aligned memory allocation if FFTW is
used (thanks, @nowls!)
* filter
- added new halfband filter design using Parks-McClellan algorithm
and qs1dsearch method to provide as exact a specification as possible
- added method to retrieve filter response from coefficients array
- dds: adding methods to get/set scale
- firhilb, iirhilb: added block processing method
- msresamp, resamp: adding method to provide the exact number
of output samples with provided input size
- msresamp2, resamp2: using better halfband filter design for
exact user specifications
- resamp: adding methods to get/set scale, fixing filter bank
resolution (was hard-coded, now respects user configuration)
* framing
- framesync64: added methods to set callback and userdata
(context) fields, adding support for exporting debugging files for
post-analysis as well as python script for processing, adding
better estimate of error vector magnitude
- msource: added convenience method to recall number of samples
generated by each source
- ofdmflexframesync: added methods to set callback and
userdata (context) fields
- qpacketmodem: returning much better estimate of error vector
magnitude
- qsource: fixed issue with carrier frequency adjustment
* optim
- added qs1dsearch object to perform quad-section 1-dimensional
search similar to bisection search, but to find potentially
non-continuous minimum/maximum of function
- Removed obsolete patches and source tarball
