## ChangeLog v0.98 (2018/09/28)

With the v0.98 release GEMMA has stabilized, is faster than ever, and
contains extensive error checking. This release contains quite a few
bug fixes, hardware-based floating point checking and speedups.

* GEMMA is faster than ever #136
* Fixes log standing 'GSL ERROR: matrix is singular in lu.c at line
  266' mvlmm regression with correlated phenotypes #179 with
  https://github.com/genetics-statistics/GEMMA/commit/99527865c00b74a3a48daa2e1e5eb7c71bd861b5 -
  (thank you @HannahVMeyer and @xiangzhou)
* Adds x86 hardware based floating point error checking #161, see 70f419673d5d3e49a3eada70c70c2d284b502d7b
* Provide a static release of GEMMA again for Linux #162
* Fixes clang++ build on MacOS #160
* Enforce failed for 0.00 in src/io.cpp at line 1431 in BimbamKin #149
* -no-check is default now
* Force SIGINT on error so debuggers can get a stack trace
* Improved CalcPab functions to not break on division by zero
  https://github.com/genenetwork/GEMMA/commit/8010061e8af476d66a0ca6fb6d509b36acdb9b9a
  (thank you @xiangzhou)
* Add Windows MingW compilation support (thanks @DannyArends)
* Fully utilizing GNU Guix containers for a build system (see INSTALL.md)
* Updated manual by @xiangzhou)

Note: This is the last purely C/C++ compilable release because we are
integrating faster-lmm-d code for new functionality in the next
version. Also we are working on a Python and R interface.

## ChangeLog v0.97 (2017/12/19)

This is a massive bug fix release with many improvements.

### Speedup of GEMMA by using optimized OpenBlas

* Binary release with OpenBlas optimization for generic x86_64 and for Intel Haswell
* Dropped using standard lapack and gslcblas libs
* Fixed NaN bug with GSL2 and made recent libraries the default
* Minimized use of Eigenlib libraries (single threaded and slow compilation)
* -legacy switch provides v0.96 behaviour (incl. eigenlib)

### Added Leave One Chromosome Out (LOCO) support for Bimbam (K and LMM)

* See 449d882a3b33ef81ef4f0127c3932b01fa796dbb
* -snps [filename] option allow selecting a subset of SNPs for analysis
* -loco [chr] option for K and LMM computations
* added [gemma-wrapper](https://github.com/genetics-statistics/gemma-wrapper) to make using LOCO easy
* LOCO examples in https://github.com/genetics-statistics/GEMMA/blob/master/test/dev_test_suite.sh

### Added checks for matrices

* #72 and #45 implements
  1. Fail if K has negative eigen values
  2. Fail if K is not symmetric
  3. Fail if K is not positive definite
  4. Warn in eigen values are very small
  5. Warn if K is ill conditioned
* Check for NaN values

### Added test framework and unit tests

* Added integration and unit tests, as well as
  [Travis-CI](https://travis-ci.org/genenetwork/GEMMA) support
* Improved debug information and testing of input files

### Other

* #81 printing out beta and se(beta) under -lmm 2 as well as logl_H1
* Improved README and INSTALL docs
* Added support info and code of conduct
* Reformatted the full source tree with 3935ba39d30666dd7d4a831155631847c77b70c4
* Merged LMM computation for Plink and Bimbam formats
* Fixed progressbar issues
* #46 removed support for Oxford format
* Got rid of all compiler warnings
* Updated copyright banner, info and license information for included software
* Started a [discussion list](https://groups.google.com/forum/#!forum/gemma-discussion)
