+HISTORY:
+2011/11/23 v0.1pre - first upload to bitbucket and all changes until
+ considered stable enough/ready to be called 0.1alpha.
+ There'll be no further descriptions until then.
+2012/06/08 v0.1alpha - first hopefully stable version
+2012/06/11 v0.1alpha-a - added headings instances, slightly rewritten
+ `exercises-tasks' object and `tasks' environment
+2012/06/11 v0.1alpha-b - added `multiplechoice' instance and `load-tasks' option
+2012/06/12 v0.1alpha-c - renamed from `exercises' into `ExSheets'
+2012/06/15 v0.1alpha-d - added more flexible solution printing method
+2012/06/15 v0.1beta - filled in some blanks in the documentation, now we need
+ some testing!
+2012/09/07 v0.1beta-a - adjustments to the updated l3kernel
+2012/09/08 v0.1beta-b - sort solutions printed with the `byID' key
+2012/09/16 v0.1beta-c - renamed option `questions-counter-format' into
+ `counter-format'
+2012/09/19 v0.1beta-d - added `topic' key, provide \includequestions with options
+ `all' and `IDs'
+2012/09/24 v0.1beta-e - added question properties and improved random question
+ selection
+2012/09/27 v0.1 - added two headings instances, new option `headings-format'
+ - small changes in the definition of the `exsheets-headings'
+ object
+ - preliminary version of totoc options. Unfortunatly
+ \exsheets@recover@number is not expandable => no
+ hyperref support
+2012/09/30 v0.2beta - version numbering gone crazy! this will now stay 0.2beta
+ until upload to CTAN (v0.2)
+ - integrated packages `translations' and `cntformats':
+ trnslt: provide expandable version of `translator's
+ \translate
+ cntfmts: outsourced previous counter formatting commands;
+ should now be usable in other packages, too, and
+ simplified definitions in `ExSheets'
+ - thanks to `translations' and `cntformats' the `totoc'
+ option now works with `hyperref'
+2012/10/05 v0.2 - removed \sumpoints and moved the functionality to
+ \totalpoints*
+ - changed meaning of \addpoints* and moved former
+ functionality to \points
+ - added bonus point functionality including \addbonus,
+ \bonus, \bonussum, \pointssum, \currentpointssum,
+ \currentbonussum
+ - added grades distribution
+ - `translations' got \LoadDictionary and \LoadDictionaryFor
+ added and loads of languages defined.
+2012/10/05 v0.2a - resolved bug in saving and recovering question number
+ using \exsheets@save@number and \QuestionNumber
+2012/10/08 v0.2b - improved the reference to chapter/solution numbers
+ in \printsolutions
+ - resolved bug in \printsolutions introduced in the last
+ update
+ - upload to CTAN
