        Main CHANGES between versions of the Browse package

1.6
 - support replay with history when calling the `Browse' method for
   character tables and `BrowseDecompositionMatrix'
 - improved `NCurses.ConcatenationAttributeLines' (adjacent strings are
   concatenated)

1.5
 - new example application `NCurses.BrowseDenseList' and `Browse' methods
   for lists of lists, and several kinds of matrices over finite rings
 - extended `BrowseBibliography' by a MSC info column,
   added the new function `BrowseMSC' that shows an overview of all current
   MSC codes
 - new example application `BrowseDecompositionMatrix' for character tables

1.4
 - provide NCurses.IsStdoutATty and NCurses.IsStdinATty, such that something
   sensible can be done in scripts or testing environments.
 - The functions used by `NCurses.BrowseGeneric' now work also when the
   output is redirected to a file.
   In particular, the file `tst/test.tst' can now be read in the background.
 - `BrowseAtlasInfo' was adjusted to the extended functionality of
   `DisplayAtlasInfo' (for GAP 4.5), and it shows now also the available
   straight line programs and related information.
 - The new example application `BrowsePackageVariables' was added.
   Currently it is undocumented, as is the analogous GAP library function
   `ShowPackageVariables'.

1.3
 - bugfixes:
   * In some situations, it had been impossible to scroll back to the first
     column once one had scrolled to the right.
   * Sorting a browse table with hidden rows by a column could yield a wrong
     result.
   * Showing text containing unprintable characters could result in error
     messages; now `BrowseData.SimplifiedString' is called in the relevant
     example applications (for example in the online help).
   * The global variable `d' (if bound) does not get a (new) value when
     the package gets loaded.
   * `BrowseDirectory' does no longer run into an error if some files in
     question are not readable.
 - new example application `BrowseProfile' (for GAP 4.5); it uses the
   currently undocumented new utility `NCurses.EditFields'
 - changed example application `BrowseGapMethods':
   * A list of operations can be entered as an optional argument.
   * The browse table is more flexible using successive categorization.
     Up to now, it was pre-categorized by operations and number of arguments.
   * Two new columns showing package names and filenames were added.
   * If the source file of the ``clicked'' method is known (this works from
     GAP 4.5 on) then this file is opened instead of showing the code of the
     function obtained with `Print'.
 - `BrowseAtlasInfo' can now be called also with a group name as its first
   argument, and it amits also the conditions (such as `IsPermGroup') that
   are admissible for `DisplayAtlasInfo'.
   The return value of the function was changed,
   now the records in the list do no longer contain the generators themselves;
   one can get the generators from these records (which are returned also by
   `OneAtlasGeneratingSetsInfo') by calling `AtlasGenerators'.
 - in `BrowseGapManuals', use `NCurses.Pager' only if the user defined pager
   is "builtin"; otherwise, use the user defined pager
 - in `BrowseGapPackages', use the global function `BibEntry' (which is
   available in the GAP 4.5 library) not `BrowseData.BibEntry'
 - generalized undocumented functions:
   * `BrowseData.SetActions' has now an optional argument that allows one
     to replace existing actions.
   * `BrowseData.PositionInBrowseTable' computes also the positions in
     header or footer.
   * `BrowseData.ReallyFormatParagraph' admits left alignment
   * `BrowseData.CompareAsNumbersAndNonnumbers' is now more efficient
 - new search/filter parameter "mode" ("substring" or "whole entry"),
   which allows one to search for whole entries and not only for substrings;
   in this case, one can search also w.r.t. "<", "<=" etc.,
   not only w.r.t. "=" or "<>"
 - successive categorization by table columns is now supported (up to now,
   existing category lines were erased upon categorizing by a column)
 - new optional third argument <what> for `DatabaseAttributeCompute'
 - changed the encoding of the files to UTF-8

1.2
 - several bug fixes, concerning
   * `BrowseTableFromDatabaseIdEnumerator' and its data format,
   * the line grid (for cells that are higher or wider than the screen), and
   * the sorting of tables in certain situations,
 - several small improvements, such as
   * a ``status bar'' in visual mode, indicating that GAP is still computing
     (that is, the screen is not yet updated),
   * a new search/filter parameter "negate", which allows one to restrict a
     table to all rows *not* matching a certain string,
   * speedup for example of sorting/categorizing, and
   * better `minyx' functions in `Browse' for character tables, which makes
     it possible to show tables with large headers on small screens,
 - new example application `BrowseTransitiveGroupsInfo'
 - rearranged example application `BrowseBibliography':
   * now it is based on database id enumerators,
   * it is more flexible via the possibility to use a record as its argument,
   * duplicate entries in the input files are supported,
   * character replacements in the input are now left to GAPDoc (using, e.g.,
     `SimplifiedUnicodeString'), and
   * new actions for showing the three formats of a selected entry were added
 - extended example application `BrowseGapPackages':
   * be aware of an empty `Persons' component in a `PackageInfo.g' file
     (up to know, this had caused an error),
   * distinguish direct and indirect dependencies,
   * improved category values in tables categorized by needed/suggested
     packages,
   * changed output format (equal to that of `BrowseBibliography')

1.1
 - after loading a workspace re-initialize kernel part of NCurses (which
   depends on type of current terminal)
 - fixed the bug that the brk-prompt sometimes was moved to the wrong
   line of the screen
 - added low level support for mouse events in visual mode and used it in
   some applications
 - made sure that TERM is set when kernel module is loaded to avoid
   exit when ncurses is initialized
 - again bugfixes in functions used by `NCurses.BrowseGeneric'
 - new feature ``database attributes'' (described in a manual appendix)
 - new (trivial but extendible) application `BrowseGapData',
   with some subapplications such as `BrowseConwayPolynomials'

1.0  generic special grid from line drawing characters,
     new actions: scroll home/end
     added components `isRejectedLabelsCol', `isRejectedLabelsRow'
     (use them in a new action for character tables)

0.99 a few bug fixes in applications,
     adjustments to the forthcoming version of GAPDoc,
     new `NCurses.BrowseGeneric' application `BrowseDirectory'
     new `NCurses.BrowseGeneric' feature ``filtering''
     extended `BrowseBibliography' to XML format source files
     (and changed the output format)


0.9  first public release with requests for comments.
