HISTORY:
v0.0 2017/02/09 - start with coding the first ideas
v0.1 2017/03/19 - first draft which actually seems to do everything as
planned
v0.2 2017/03/21 - bugfix in the verbwrite module
- add `use!' and `print!' properties
- add the concepts of `noupdate' and `boolean' properties
v0.4 2017/03/24 - \IfExerciseBooleanPropertyTF
- \GetExercisePropertyTF, \PropertyValue
- \printallsolutions
- \UseExerciseTemplate
- bug fix in solution environments: now get printed again
when option `print=true' is used
- bug fix to the translations of the solution list headings:
exercise name instead of exercise type is now printed
- \AddtoExerciseTypeGoal, \AddtoExerciseGoal
\AddtoExerciseTypeGoalPrint, \AddtoExerciseGoalPrint,
\ExerciseGoalValuePrint
- \addpoints, \addbonus, \points, \printgoal
v0.5 2017/03/30 - add style file mechanism
- make solution print conditions `section' and `chapter'
combinable
v0.5a 2017/04/15 - fix wrong translation of the `default-heading'
v0.5b 2017/04/16 - add \SetExerciseProperty
v0.6 2017/04/27 - official interface for grade distributions
- refine hook management (environment module)
v0.6a 2017/04/28 - refine \blank command, add documentation for said command
v0.7 2017/05/09 - \xsim_list_length:n
- new boolean property `used'
- when an exercise is collected the counter isn't stepped
but only when the exercise is inserted for the first
time; when this happens the new property `used' is set to
`true'
- make setting boolean properties case insensitive
- add missing pieces to manual (eg `page' property...)
- \TotalExerciseGoals and \TotalExerciseTypeGoals
- \XSIMifchapterTF

\IfExerciseTypeGoalsSumTF and \IfExerciseGoalsSumTF

- random exercise lists from collections
- \xsim_collection_count:n
- \GetExerciseIdForProperty and \GetExerciseTypeForProperty
for unique properties
- set property `print=false' during collection and only to
true when the corresponding exercises actually are
printed
- do not insert \par at the beginning and end of exercises
and solutions; this should be left to the templates!
- new option `print-collection/print' which allows to
choose between exercises, solutions, and both to be
printed
- new parameter `solution-counter' in order to avoid
possible conflicts with existing counters
v0.8a 2017/05/19 - \IfPrintSolutionTF
v0.8b 2017/05/23 - use \printgoal in default environment template
- \xsim_print_goal:nnn now expands input to a number

- option `blank/fill'
- bug fix in \xsim_start_collection:nn

- new option `file-extension'
v0.10a 2017/10/01 - bug fix: grading table options can now be set with

v0.11 2018/02/12 - change name requirement for style files in order to
prevent possible name clashes with module files
- fix bug in \SetExerciseProperty and

kind
- \ProvideExerciseTagging
v0.12 2019/09/30 - add parameter versions for the plural forms of exercise
and solution names

v0.13 2019/10/06 - experimental package option `no-files'
v0.14 2019/10/13 - new exercise parameters `exercise-heading' and
`solution-heading'
- new options `exercise/heading' and `solution/heading' as
interface for setting the new parameters

parameters in environment templates
- change the environment template `default' to use the new
\GetExerciseHeadingF and output a \par at the end

v0.19b 2020/04/04 - fix bug in new attribute mechanism which was a problem
when `no-files` has been used
v0.20 2021/01/31 - switch to one sty file per package
- use LaTeX's new hooks
- declare undeclared variables
- new exercise setup mechanism which clearly determines the
difference between definition, usage, and printing of an
exercise; this also solves the problem with added goals
in the exercise body in a collection
- re-write collection mechanism:
* changes the behaviour of \collectexercises but doesn't
require external files any more and more importantly
doesn't require inputting files several times for
multiple collections
* drop \collectexercisestype
* new \(de)activatecollection
* new options `collect' and `<type>/collect'

- reduce comment line in automated comments in exercise and
solution files
