Changes in version 0.4-0
The classes for linkage of big data sets have been redesigned. The mechanism of creating comparison patterns on the fly from a database is replaced by saving all comparison patterns in a ffdf object (disk-based data frame, see package ff). This approach limits the amount of comparison patterns with respect to available disk space (the database approach was designed to handle even more patterns, at least in theory), but is more efficient regarding execution speed. In addition, some methods that were only usable with the S3 class RecLinkData, can now be used with RLBigData objects, most notably getMinimalTrain().

For the structure of the redesigned classes, see the documention entries for classes "RLBigData", "RLBigDataDedup" and "RLBigDataLinkage".
:wq

Changes in version 0.3-5
	-bug fixes:
		-getExpectedSize failed in rare cases
Changes in version 0.3-4
	-added summary method for RLResult objects
	-bug fixes:
		-summary.RecLinkResult failed for object without known
		 matching status
Changes in version 0.3-3
	-added new classification method "bumping", see ?trainSupv
	-bug fixes:
		- string comparators crashed for character(0) input
		  (reported by Dominik Reusser)
		- getPairs could fail when the result is emtpy
	-various performance improvements
	-renamed vignette "Fellegi-Sunter Deduplication" to 
	 "Weight-based deduplication"
	-package is now in a namespace

Changes in version 0.3-2
	- performance improvements in various functions
	- bug fixes:
		- epiClassify failed for datasets with only one column
		  (reported by Richard Herron)
		- getErrorMeasures returned wrong values in rare cases

Changes in version 0.3-1
	- fixed bug in emClassify that threw an error during  classification 
	  with on-the-fly calculation of weights
	- added checks in unit tests
	- fixed bug in optimalThreshold which caused wrong results in some
	  cases when ny was supplied
	- added status messages and progress bars to various classification functions
	- fixed numerical problem that produced wrong thresholds in some cases
    for emClassify (with my / ny supplied) 

Changes in version 0.3-0

	- A framework of S4 methods and classes tailored for processing large
	  data sets has been added. See the vignette 'BigData' for details.
  	- The output format of getPairs (existing method for RecLinkData and
	  RecLinkResult objects) has changed: Column "Weight" is now last instead
	  of first. Also, for single.rows=FALSE, record pairs are speparated by
	  a blank line.

Changes in version 0.2-6

	- added subset operator [ for RecLinkData and RecLinkPairs objects
	- improved running time of epiWeights significantly

Changes in version 0.2-5

	- Fixed a bug in getMinimalTrain which caused the function to fail

Changes in version 0.2-4

	- Fixed a bug in getMinimalTrain that caused pairs with unknown
		matching status to become non-matches in the training set.
	- Some examples were modified to reduce execution time.
	- Unit tests have been added in inst/unitTests.
	- Checking of arguments improved in some functions.
	- Small documentation changes.
Changes in version 0.2-3

  - getParetoThreshold now prompts a message if no data lies in the
    interactively selected interval and asks the user to choose again
  - Corrected maintainer e-mail address
  - Several bug fixes
