Create RC, and after that
Release
About code freeze

To release Tera Term installation package is shown in the following step:

Start release operation

Confirm ticket and branches.
- Confirm in project team.
  - Organize / decide whether to include bug fix / feature in this release or defer.
- Merge branches
  - working branches, cherry-pick to stable branch
- Close issues.
  - Close fixed or responded issues.
  - Change the milestone for issues which is planned respond in the next release.
- Decide respond or postpone about new issue.
Confirm tools, libraries, import sources.
- Visual Studio (https://visualstudio.microsoft.com/)
- Inno Setup (https://jrsoftware.org/isdl.php)
- Oniguruma (https://github.com/kkos/oniguruma/)
- SFMT (http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/index-jp.html)
- LibreSSL (https://www.libressl.org/)
- zlib (http://www.zlib.net/)
- The reference C implementation of Argon2 (https://github.com/P-H-C/phc-winner-argon2/)
- cJSON (https://github.com/DaveGamble/cJSON/)
- Unicode (https://www.unicode.org/versions/latest/)
Library versions are mostly determined at this timing.

We use CI tool for release build. For this reason, the detailed version of Visual Studio is uncontrollable. The detailed version will depend on what version is adopted by the CI tool.
What change is included in this release of not included is mostly determined.

From create RC until release

Confirm documents.
- Check for missing parts of documents. Configuration item on dialog, special options without UI, command line parameters, new macro command and so on.
- Check for changelog. Add it if found missing.
- Change order of changelog. Important changes will be located at upper position. Order is terminal emulation, application and macro.
- Check for translations of changed documents. Translate them if they are not translated.
Increment the version while RC release process.
- teraterm\common\tt-version.h
  set TT_VERSION_SUBSTR to "RC".
```
  #define TT_VERSION_MAJOR             5
  #define TT_VERSION_MINOR             4
  #define TT_VERSION_PATCH             0
- #define TT_VERSION_SUBSTR            "dev"
+ #define TT_VERSION_SUBSTR            "RC"
```
  TT_VERSION_MINOR or TT_VERSION_PATCH is already incremented yet. It is incremented immediately after previous release.
- ttssh2\ttxssh\ttxssh-version.h
  TTSSH_VERSION_MINOR or TTSSH_VERSION_PATCH is already incremented yet. It is incremented immediately after previous release.

By way of exception, CygTerm+ always upgrades not regarding Tera Term release process when the patch is committed.
The release date is the day committed by a developer. Therefore, the code modify, version increment and add changelog should be committed at the same time.
Because user can get gcc compiler for free.
Increment the year of last publication of copyright notice if it is first release in this year.
