------------------------------------
V2.5b   2019-03-10

- Bug fix: The new algorithm introduced in v2.4 still tended to produce
  "double sit out" or "not enough dancers found" errors under certain 
  circumstances. Hopefully better now.

- Bug fix: In a situation where a whole square would have to sit out
  because of an unbalanced number of belles and beaus the program now
  aborts mixing with an error message, requesting to switch more dancers
  to dance both positions.

- Bug fix: Prevent active dancers from being deleted in the edit user dialog
  during a dance, as this did break the program.

- Feature: You can now mix using the barcodes "NEW" or "OPEN".
  The special barcode PDF now also provides these codes.

- Documentation for WiFi access

------------------------------------
V2.5a   2019-02-21

- Bug fix: The new algorithm introduced in v2.4 tended to produce
  double sit out errors, especially often for small groups (9 to 15 dancers).
  This shouldn't happen any longer. 

- Bug fix: Switching of "posmode" on the admin screen did not work correcty.

- Bug fix: Adding additional barcode fields on the user edit screen did
  not work on older web browsers (not supporting the outerHTML property)

- Feature: It is now possible to ignore a double sit out error.
  In certain situations (e. g. during a class with 12 class members
  that are allowed to dance every tip and 9 angels), this might be
  necessary.

- Feature: The mini statistic box shown when mixing the squares has now
  links that allow you to list dancers scheduled to dance a special dance
  position. In case of an unbalanced number of dancers, this makes it easier
  to change some of the dancers.

- Many new dancers in dancer-190221-tri.data

------------------------------------
V2.5    2019-01-08

- New: Dancers can now have more than two barcodes. Use the "+" marker at the
  end of the barcode list on the user edit screen to add as many barcodes as
  you need.
  This required a new dancer.data file format and a new database structure.
  NOTE 1: After an upgrade, use the "database: check" function to
  update your database.
  NOTE 2: Old program versions will not be able to import the new data.dancer
  file format.

- New: Barcodes can now be printed for a given number range.

- Bug fix: When using the "avoid" feature, tip gereration could fail 
  with error message
  "Check tip error: Warning: sprintf() [function.sprintf]: Too few
  arguments in sd-v2.4/src/tipinc.php on line 168"

  barcode was printed between the end and the start of the repeat sequence

  after the end of the PDF code

- Documentation fixes and updates

- German language release notes in the file "aenderungen.txt"

------------------------------------
V2.4     2018-10-16

- New algorithm for deciding who dances beau and who dances belle, that
  hopefully solves the long known bug of the program that led to unwanted
  splits of fixed couples, especially of couples that are not composed of
  exactly one beau and one belle.
  This is enabled by default and can be deactivated using the new 
  "Pos mode" option on the admin screen. Please report if you should run
  into problems.

- On the admin screen, the "Class couples" setting showed
  the wrong status when in "normal" or "ignore students" mode

- A new option "repeat" for barcode printing allows to fill
  the rest of the page with a repetion of the selected barcodes.

- Bug fix: Redo breaks the program when used on an open tip or
  with no previous tips.

- Additional documentation for dancer.data

------------------------------------
V2.3     2017-11-17

- Modified licensing algorithm for Windows 10
  This will (hopefully) save Windows 10 users from losing 
  their Triangles Rotation license on major Windows 10 updates.

  Rotation license key! The update can be obtained online and automatically.

  (especially short names with multiple dots at the end).


------------------------------------
V2.2     2015-05-03

- New "avoid" feature added.
  Please note that this required a change of the 
  database structure, so use "check database" after the update
