	o Development 1.99.8
		o Algorithm is now optimized for speed.
		o Added unit tests.
		o Compressed all datasets with the smallest possible format.
		o Added data imputation function. In the manual, we added this function with the note "In development".
		o Changed parameters in HVar function to make it less stringent.
		o Allow PCA and HClust to utilize data imputation. Since these two tests are more prone to zero counts, we find that data imputation can help improve their performances.
			o Note that t-SNE does not need data imputaiton and is the preferred method for cell subpopulation analysis.
		o PCA is speeded up using gmodels library.
	o Release 1.2.8
		o We now formally declare Linnorm version 1 to be deprecated.
		o Release 1.2.7 and 1.2.8 are already implemented with many modifications that are intended for Linnorm 2. Still, Linnorm version 1.99.8+ will allow more functionalities. We strongly suggest using the newer version.

17th, January, 2017
	o Development 1.99.7, Release 1.2.7
		o Finally, build is successful on bioconductor.
		o minZeroPortoin argument is renamed into minNonZeroPortion (minimum non-zero portion filtering threshold), to better reflect its real function.

2nd, January, 2017
	o Development 1.99.0
		o Improved Linnorm's algorithm
			o Added data filtering step
			o Added normalization step
		o Added new functions for normalization, t-SNE clustering.
		o Almost all functions are updated.
	o Release 1.2.1
		o It now matches 1.99.0 as much as possible.

6th, October, 2016
	o Development 1.1.16:
		o Removed warnings from loading package.
		o Fixed and updated vignettes based on Bioc Staff recommendation.
		o Implemented Linnorm.HClust function.
		o Updated Linnorm.Cor function for clustering functionalities.

27th, August, 2016
	o Development 1.1.14:
		o Updated Linnorm.Cor function to allow more functionalities.
		o Updated vignettes on Linnorm.Cor.
		o Updated reference manual.
	o Release: Fixed building error in 1.0.5, thus becoming 1.0.6.

23th, August, 2016
	o Critical update for development version 1.1.13:
		o Added Linnorm.HVar, Linnorm.Cor functions for highly variable gene discovery and gene correlation network analysis.
		o Added input argument for users who wish to reuse Linnorm transformed datasets in various functions.
		o Added keepAll argument for users to control whether filtering would remove some genes from the results.
	o Author list update in release 1.0.5.

17th, August, 2016
	o Updated author list.
	o Error preventing checks now implemented in release 1.0.4.
	o Critical: Fixed a bug that might cause Linnorm to underestimate fold change.

21st, July, 2016
	o Several new updates for the last few versions:
	o PCA analysis pipeline has been added to Linnorm.
	o Error preventing checks have been implemented, as suggested by Dr. Jing Qin. Thanks.
	o Vignetes updated and its graphics are fixed.

16th, March, 2016
	o Version 0.99.0 is going to be submitted to Bioconductor Today.

10th, March, 2016
	o Congratulations, this is the first news for version 0.99.0.
