* opensource COBOL 4J 1.1.7-hotfix1

** New Features

  (1) Fix bugs related to UTF-8
    * With older versions, DISPLAY statements output invalid UTF-8 data when the arguments are sub items of group fields.
    * With older versions, initilizing data with VALUE clauses fails in some cases.

-----------------------------------------------------------------------

* opensource COBOL 4J 1.1.7

** New Features

  (1) Implement the environment variable `COB_TERMINAL_ENCODING`.
    * If the value of `COB_TERMINAL_ENCODING` is `UTF-8`, the DISPLAY statement outputs data after converting it to UTF-8. Otherwise, it outputs raw data (typically encoded in Shift JIS).
    * If the value of `COB_TERMINAL_ENCODING` is `UTF-8`, the ACCEPT statement processes input data as UTF-8 encoded. Otherwise, it processes input data as Shift JIS encoded.
  (2) Fix the UTF-8 compatible compiler to recognize that the size of multibyte characters in COBOL source code as 2 bytes instead of 3 bytes.
    * This change allows users to write more multibyte characters on each line of the COBOL source code.

-----------------------------------------------------------------------

* opensource COBOL 4J 1.1.6

** New Features

  (1) Compile UTF-8 Source Code
    * The latest version of cobj is now able to accept UTF-8 encoded COBOL and generate UTF-8 encoded Java.

-----------------------------------------------------------------------

* opensource COBOL 4J 1.1.5

** New Features

  (1) Convert string literals containing SJIS characters to Java string literals. (#561)
    * The older versions convert string literals containing SJIS characters into byte arrays with hexdecimal integers.
      * Older versions convert `"日本語"` into `CobolUtil.toBytes((byte)0x93, (byte)0xfa, (byte)0x96, (byte)0x7b, (byte)0x8c, (byte)0xea)`.
      * Latest version converts `"日本語"` to `CobolUtil.stringToBytes("日本語")`.

** Bug Fixes

  (1) Fix comparisons of COMP data.
    * With older versions, comparisons of COMP data are invalid in some cases.

-----------------------------------------------------------------------

* opensource COBOL 4J 1.1.4

*** Bug Fixes
  (1) Process Japanese identifiers in COBOL correctly (#540)
    * The older versions convert some Japanese characters in COBOL identifiers to another characters in Java.
  (2) Fix the conditions `PERFORM UNTIL` (#544)
    * If COBOL source code contains divisions in conditions of `PERFORM UNTIL`, the older versions emit compile errors.
  (3) Fix `SEARCH` statements with data specified `OCCURS` and `DEPENDING`(#545)
    * The older versions emit compile errors when `SEARCH` statements with data specified `OCCURS` and `DEPENDING`
  (4) Fix `ADD` statements and `SUBTRACT` statements (#546)
    * In some case, the result of `SUBTRACT` was previously incorrect when the operands contais PIC S9(n) negative values.
    * In some case, the result of `ADD` was -0 instead of +0 previously.
  (5) Fix the process of checking signs of PIC 9(n) containing spaces (#549)
  (6) Fix `INSPECT` statements (#550)
    * The older versions change signs of some values accidentally because of the bug of `INSPECT` statements.
