- Bug 6919.  For multi-part problems containing perl script blocks inside
  part(s), if question type = randomizetry, the first call to &random()
  for each part needs to set the new seed.

- For 2.11.2 (modified)
  Include changes in rev. 1.176

- Bug 6903. Args passed to &Math::Random::random_set_seed() need to be
  within bounds, otherwise use &Math::Random::random_set_seed_from_phrase()

- Bug 6873
  Shorter name for function: &conv_eng_format(). Add documentation

- Bug 6873
  LONCAPA-prerequisites needs perl-Number-FormatEng.

fixed bug 6844

avoiding the missing $ in m warning with chemparse

added input_id sub for bug 6821

- Add mapalias as an optional sixth arg in LON-CAPA function:
  &submission() used to retrieve student's submission for a specific
  problem/part/response ID for use in a different problem/part in course.

- Bugs 6609, 6611, 6614
  - Optional fifth arg can be provided to &submission() to clean up learner
    submitted data (e.g., in a multi-part problem) where learner data from
    submissions to a numerical respnse in an earlier part will be used as
    variables in the script block when calculating answers for a later part.
  - "cleanupnum" arg is a ref to a hash, with one or more of the following
    keys => values:
    exponent => 1, comma => 1, letterforzero => 1, spaces => 1, format => 'ns'
    (where n is an integer, i.e., number of significant digits).

- Bug 6693
  - submission can be ref to an array if there are multiple <value></value>
    items within an <answer> tag.

- Bug 6613
  Handle formatting correctly for numbers with absolute values of 10^15
  or larger, and numbers smaller than 10^-4 in &format_significant_figures(),
  in which perl automatically uses exponent form for initial value of $numSig.

- Bug 6645.
- "Computer's Answer" - append correct number of trailing zeros to satisfy
  significant digits format, in a particular rounding situation.

- Bug 6577
  - More generalized solution than implemented previously in rev. 1.163.
  - e.g., computed answer: 1900, can be formatted 3s (1.90E+3).
    same for computed answer: 1.900E+3, can be formatted 3s (1.90E+3).

Bug #6693: New optional parameter to allow the author to encode the student's submission provided by the function &submission().

- Bug 6577.
  - Eliminate warnings about significant figures where answer format is set
    to be S, but correct answer is an integer with multiple trailing zeroes.

- Backport 1.162.

- Bug 6629.
- Re-establish availability of ln() function in script blocks for Linux
  distros running perl 5.10.1 or newer.

- Backport 1.153, 1,154, 1.155, 1.156, 1.157, 1.158, 1.159, 1.161.

- Check customunits contains other than white space before calling split().

- Backport 1.160.

- Bug 6466.

Format: unita=unitb,unitc=4*unitb,...

Bug #2020: pre-processing of numerical, formula, and string response
Bug #5100: degrees Fahrenheit, etc

Bug #2020: work on preprocessor

Bug #6311: Allow for algebraic input in numerical response

Function to generate wrong answer bubbles

Easier access to parameters and stored data.

Accessing additional course data

- Efficiency: use a single loop to check for control characters and populate
  answerstring for stringreponse.

- Bug 5531.
 caparesponse.pm
  - For stringresponse: (case (in)sensitive) computer's answer available
    in detailed submission display.
  - Student username in warnings on control characters etc. renamed $sname
    instead of $name (already in use in different scope) to improve code
    readability
  - computer answer available for legacy stringresponse submission (e.g.,
    for bug 5531 detection script -see neutrinohavest.pl)
    if grade_retrieveanswers included in form for answer target.

 default_homework.pm
  - fix detection of control characters in answers - answers will be in
    an array
  - computer's answer returned by &caparesponse_check_list()

 loncommon.pm
  - &format_previous_attempt_value() handles display of computer's answer.
  - fix typo in phrase for localization (no current translations in
    localize/*.pm to update).

- Bug 5531.
  - remove control characters from student submission for stringresponse,
    unless "computer's answer" also includes control characters.
    (correctness evaluated with control characters removed).
  - log to lonnet.log if control characters were removed (if <CR>, <FF> or
    newline, escape these control characters, when included in log report).

- Bug 5531.
  - Detect where student resubmits previous answer for case sensitive
    stringreponse item and award changes to EXACT_ANS.
    Detect for case insensitive stringresponse when previous award changes
    to EXACT_ANS for submissions whch only differ by case.
    - logs to lonnet.log and sends e-mail to recipients of "errormail" for
      course domain.
  - For cs and ci types if award is INCORRECT use perl to compare
    response with answer, and log if disagreement with result from
    strcasecmp() or strcmp() to capa_check_answer() in capaCommon.

- Don't add trailing space if no unit to append.

Dealing with percentages if the author entered %, but the student did not.

Bug #5796: confusion when asking for "percentage"
undoing Bug #1967 - the side effects of the medicine are worse than
the illness

Paul Rubin's interface to R.

Works now. However, it needs additional Perl libraries, which are currently
commented out. Also, an R-package needs to be installed.

Support for R CAS
- needs testing
- better error handling
- correct blacklist
- correct list of allowed libraries

There are problems coded as formula resonse WITHOUT sampling requiring the student to enter a set (such as {4,2,b,z}).
As of version 1.142 sets as student's input would return BAD_FORMULA, because they contain commas.
With this version BAD_FORMULA will only be returned if the response contains a , but not a set.

These set problems are inpossible to code using mathresponse as it splits the response at commas. Hence RESPONSE[1]='{4' for the above set which is not a legel maxima expression.
These set problems could be coded by customresponse in combination mathresponse. customresponse would be used to remove the curly brackets. This way of coding, however, is very ackward as compared to formula response.

Formularesponse will not accept a comma in an individual submission  - either as a scalar answer or within a single component in a vector answer (for vectors: components are split on , prior to this evaluation phase).

Bug 5806. Although % is not a LON-CAPA unit it has apparently been used as such.
- Revert to pre-1.133 behavior (2.6.X and earlier) for published problems where the unit was set to %.
- Work in progress if % is to become a 'real' unit.

- Bug 5793
Alternative solution.  Revert default_homework.lcpm to 1.138. No longer need to pass tag arg to caparesponse_check_list().
- Instead set $$args_ref{'type'} to 'ci' (the default) if type attrib is missing or null in the corresponding <stringhint> (hint.pm), or <stringresponse> (caparesponse.pm) tags.

- Bug 5531 (although should really be a separate bug).
RegExp used to separate units from numerical part of an answer can truncate responses to stringresponse items for which the type has not been explicitly set (as ci, cs, mc or re).

- Include the tagname of the response item in calls to caparesponse_check_list(), so that if the type attribute is unspecified, stringresponse submissions are not subjected to the unit extractor.

Perhaps there is a reason why this ambiguity has not been eliminated previously by passing the tagname to caparesponse_check_list() - run in the safe space?
Testing needed.

Fix bug 5785.
- Removal of spaces from user responses to stringresponse questions when checking for correctness is a side effect of rev 1.133 which addressed bug 4680.

Bug #5738: be able to load libraries into Maxima

Accessor functions for more stuff

The &due_date, etc, functions now return correct timezones and languages.

answer_date, due_date, and open_date take partid as parameter

Bug #4680: zero does not need units

Bug #1967: accept percentages as numerical answers, such as "80% c" for
eighty percent speed of light.

Let's hope for the best.

Bug #1677: cc as unit (and a few others that people apparently wanted)

A unit has at least one non-digit character.

Bug #3991:
* correctly split off units
* then apply implicit multiplication rules

Bug #4721: don't interpret whitespace in number as part of unit

For dollar-type problems (e.g., answer: "$1.99"), the Computer's Answer was
wrong (computer would enter "1.99 $").

Bug #1159: entering an equation is not INCORRECT

&cas()

Make formula fix work with <mathresponse>

    Still borken:
    <answer type="unordered"><vector>1,2</vector><value>3</value></answer>

- saving some notes for future speed up possiblities

   - additionally 64bit3 now uses all 64bits of the seed
   - also added new function pushrandomnumber poprandomnumber to be called instead of setrandomnumber before we were crunching the Safe space random number generator state, as this function is used bu thing the <optionresponse> and <radoibuttonresponse> this meant changes in the internal randomization code could screw up later Safe space random calls the old method is preserved for blank 64bit and 64bit2 randomiztion env.
