+Changes in version 1.2.3
+------------------------
+
+* Fixed bug in convertBytesToLong method in the BinaryUtils class.
+
+* Added OSGi bundle metadata (contributed by Dave LeBlanc).
+
+* Updated documentation to explain why setSeed does nothing for any of the
+ RNGs.
+
+
+Changes in version 1.2.2
+------------------------
+
+* Fixed serialisation of MersenneTwisterRNG and CellularAutomatonRNG.
+
+* Made XORShiftRNG and CMWC4096RNG thread-safe.
+
+* Added source JAR to distribution.
+
+
+Changes in version 1.2.1
+------------------------
+
+* Converted internal state of XORShiftRNG from an array to five separate
+ fields. This results in improved performance. Optimisation suggested by Jos
+ Hirth.
+
+* Optimised the Probability class so that it doesn't make an RNG call when the
+ probability is 1.
+
+* Added swapSubstring method to enable efficient exchange of data between two
+ BitStrings.
+
+
+Changes in verison 1.2
+----------------------
+
+* Added two new fast PRNGs (CMWC and XOR). CMWC provides a very long period
+ and the XOR RNG is twice as fast as the Mersenne Twister. See
+ http://school.anhb.uwa.edu.au/personalpages/kwessen/shared/Marsaglia03.html
+ for descriptions.
+
+* Fixed RandomDotOrgSeedGenerator so that it can generate seeds > 1kb in size.
+
+* Changed RandomDotOrgSeedGenerator so that it uses HTTPS for communicating
+ with the website (ISSUE#9).
+
+* Introduced the Probability class, a new numeric type. This immutatble value
+ type encapsulates a probability value between zero and one. The class
+ enforces the 0..1 bounds and provides convenient methods for working with
+ probabilities.
+
+* Added Rational type to enable arithmetic on rational numbers without loss of
+ precision.
+
+* Added restrictRange methods to Maths class. These adjust a given value so
+ that it falls between specified minimum and maximum values.
+
+* Made caching of BigInteger factorials thread-safe.
+
+
+Changes in version 1.1
+----------------------
+
+* PermutationGenerator and CombinationGenerator now implement
+ java.lang.Iterable (ISSUE#1).
+
+* Moved PermutationGenerator and CombinationGenerator into new combinatorics
+ package.
+
+* Moved NumberGenerator and its implementations into new number package.
+
+* Added demo program for different probability distributions (ISSUE#2).
+
+* Added method to the DataSet class for calculating the harmonic mean.
+
+* RNGs no longer log any information to stdout (ISSUE#7) by default.
+ The DefaultSeedGenerator class will log the seeds that it generates
+ only if the org.uncommons.maths.random.debug System property is set to true.
+
+* Relaxed restriction on the maximum size of the element set used by
+ CombinationGenerator. The maximum was 20 but bigger sets are now permitted
+ as long as the total number of combinations is no more than 2^63 (ISSUE#8).
+
+* Added a cache for BigInteger factorial values. This avoids expensive
+ recalculation in code that repeatedly computes factorials.
+
+
+Changes in version 1.0.2
+------------------------
+
+* Added generator for exponential distribution.
+
+* Fixed possibility of out-of-range values in continuous uniform generator.
+
+* Modified AESCounterRNG to allow seed size (AES key size) to be specified.
+ Defaults to 128-bits. 192-bits and 256-bits are supported but they require
+ the unlimited strength cryptography policy files (available from Sun) to be
+ installed on the local machine.
+
+
+Changes in version 1.0.1
+------------------------
+
+* Added minimum, maximum and median methods to DataSet class.
+
+* Fixed logic around zero-length combinations and permutations.
+
+* Improved unit test coverage.
