Summary of what's new:

• Version 7.7.0
• Cryptarithms and Hill ciphers now check the question to make sure that it matches the problem. A new tool has been added when creating a test to allow adjusting the question score values of the overall test to allow distribution of the last two digits of the score in order to reduce the likelihood of a tie.
• Version 7.4.0
• Cryptarithms now have a generator which will search sets of words to give problems to choose from. As always, please report any problems at github.com/toebes/ciphers/issues.
• Version 7.1.3
• Cryptarithms should be fully supported now. As always, please report any problems at github.com/toebes/ciphers/issues.
• Version 7.0.0
• Addition of the new ciphers for the 2022-2023 season. As always, please report any problems at github.com/toebes/ciphers/issues.
• Version 5.8.3
• We have pushed quite a few fixes for the integration with Scilympiad. Additionally, the user experience for uploading images of working on paper has been completed, but there still are a few things to be done before it will be turned on. As always, please report any problems at github.com/toebes/ciphers/issues.
Previous Versions...
• Version 5.6.0
• We have added support for Railfence offsets for division C along with some new experimental support to allow for uploading pictures of paper copies of a test. We have also enhanced the baconian cipher to allow emojis and other fancy characters as well as support for spaces when generating a sequence.
• Version 5.0.0
• This represents a major change in the underlying test model data structure which should result in significantly better performance for the server when generating/loading/scoring a test. We have tried our best to make it backward compatible with any tests previously generated on the server. If you notice any problems with the realtime tests, please report any problems at github.com/toebes/ciphers/issues.
• Quite a few bugs have been fixed including scoring of Vigenère ciphers and better tracking which ciphers are legal for the different tests.
• Version 4.2.0
• Implemented many of the new features for the season including the Porta Cipher, Special Bonus Questions and keyword solutions.
• Version 4.1.2
• Implement tracking of out of browser time for when the main window is not active. It now shows a "OBT" message in the timer window tracking the total time that the window was not active. Track time changes more accurately.
• Version 4.1.1
• Minor fix to track attempts to change the local time on the client. Updated privacy policy.
• Version 4.1.0
• Many bug fixes for importing schedules for tests. Clean up error messages when publishing a test.
• Version 4.0.5
• Fix elusive bug which caused the system to sometimes lose Affine answers.
• Version 4.0.4
• Catch expired tokens which were generating odd error messages about missing id.
• Version 4.0.3
• Eliminated caching the time calls so that local browsers on Linux wouldn't end up with an incorrect time. Major rewrite of the scoring software to be more efficient with the server.
• Version 4.0.2
• We have cleaned up the code for settings dates for scheduled tests to prevent invalid ranges and email addressed from being entered and removed any tests which had dates which were out of range and invalid email addresses which could cause problems on the system.
• Version 4.0.1
• Minor update to allow for UI feedback when creating/deleting tests as well as setting permissions on the tests.
• Version 4.0.0
• This is a Major rewrite of the backend server to increase performance and number of users for the system. Please feel free to report any bugs at github.com/toebes/ciphers/issues This also includes an update to automatically delete any test taken after two weeks. As part of keeping data safe for all users, any personally identifiable information is automatically deleted when the corresponding tests are deleted. This includes any names or email addresses which are associated with a test.

  The mobit and pollux scoring algorithm has been updated. The answer letter needs to be under at least one of the morse digits and that ONLY one answer letter can be under the digits for a morse character

• Version 2.2.2
• Add support to decode 3x3 matrices for the Hill Cipher.
• Version 2.1.1

  Division A
  . Add support for type of event to the test type for validating Cipher usage.
• Version 1.4.5
• Stabilize the code combo for RSA question so that it doesn't change when editing. Updated Vigenère so that it proprerly displays lower case key strings.
• Version 1.4.4
