v2.1.0

• Bug fix: Display empty string if dumped-date is not set (instead of printing null)

Code refactoring

• Simplified factory pattern
• Replacing abstract class with interface
• Made Name-enum nested inside Emulator

v2.0.1

Bug fix: No longer crashes when parsing invalid "dumped-dates" in YYYY-MM-DD-format

v2.0.0

• Bug fix: Make maven run unit tests

Breaking changes:

• API changes: Id666-class method return type changed from String to LocalDate

public String dateDumpWasCreated() // re-named method
public LocalDate getDateDumpWasCreated() // new method

• Id666 "dumped date"-parsing is now spec compliant:

Background

• Most dumped-dates in text-tag format are stored in the ISO-8601 date-format
  (YYYY/MM/DD).

• The spec however, clearly states that text-tag dump-dates are in: MM/DD/YYYY-format.

Old behaviour

• Dates were parsed as: DD-MM-YYYY if possible.
• For example: 06/12/1999 was parsed as 1999-12-06 (6 December 1999)

New behaviour

• Allowed formats: YYYY-MM-DD, MM-DD-YYYY
• Sometimes allowed: YYYY-DD-MM, DD-MM-YYYY
• For example: 06/12/1999 is parsed as 1999-06-12 (12 June 1999)

Parsing rules

1. Try to parse as ISO-8601 date YYYY-MM-DD
2. Try to parse as spec-date MM/DD/YYYY

• a) If month/day is invalid in step 1 or 2. Swap them and parse as DD/MM

Examples:

• 2005-31-12 gets parsed as 2005-12-31
• 31-12-2005 gets parsed as 2005-12-31
• 05-12-1999 gets parsed as 1999-05-12
• 31-31-2005 fails parsing
• 2001-02-29 fails parsing (not leap year)

v1.2.0

• Migrating to JUnit 5 (jupiter)
• Refactor unit tests to use parameterized tests (data providers)

v1.1.0

• Lenient date-string parsing. Allow dash-separator - in "dumped date"-tags
• For example: 12-31-2000

v1.0.1

• Bug fix. Fix crash on MM-DD-YYYY date-format for "dumped date"-field.
• MM-DD-YYYY is now allowed for text-format tags (as stated in the spec)
• Note that dates will be parsed as DD-MM-YYYY if permitted

v1.0.0

• Breaking change: "Dumped date"-field (Id666) is consistently formatted on output as yyyy/MM/dd
• For example: Date SPC was dumped: 2003/12/24

Old behaviour

• Binary tags: yyyyMMdd (20031224)
• Text tags: Inconsistent. Any 11 (sic) byte string allowed

New behaviour

• Binary tags: Date SPC was dumped: yyyy/MM/dd
• Text tags: Date SPC was dumped: yyyy/MM/dd

Parsing

Text tags

Permitted date formats:

• yyyy/MM/dd
• dd/MM/yyyy

v0.3.9

• Fix bug in SPC spec (binary dump date)
• Log warning if "dumped date"-field pre-dates birth of SPC-format (from SPCTool). Only implemented for binary tags.
• Fix typo in assertion message
• Code refactoring
• Add more unit tests for parsing of textual SPC-tags

v0.3.8

• Fix broken binary dump-date parsing.

Binary dump dates are stored as:
byte, byte, short { day, month, year }
in little-endian format.

Previously they were incorrectly parsed as a 4-byte int and thus failed to parse as a valid ISO-8601 date.

Buggy behaviour

09:25:57.125 WARN: Invalid date format: java.time.format.DateTimeParseException: Text '131402265' could not be parsed at index 0
09:25:57.129 WARN: Setting dump date to empty as fallback

v0.3.7

• Fix bug in xid6 "dumped date"-validation

Dates such as 20040404 failed to set the xid6 "dumped date" tag and resulted in
a log warning. Xid6 "dump dates" are extremely rare so this never happened in practice
