Package: mozc Version: 1.6.1187.102-1~exp2 In short, --channel_dev=0 option should be removed form debian/rules. Otherwise, Mozc reports its version as 1.6.1187.2 rather than 1.6.1187.102.
Background: I know that build number was displayed by default on the candidate window of IBus and our build instruction page described that you can use --channel_dev=0 option to hide the build number. However, starting with Mozc 1.4.1033.102, the build number is no longer displayed on the candidate window even if you do not specify --channel_dev=0. Furthermore, we changed our build script so that the version can be automatically calculated by the channel name. As a result, the version will is now calculated as 1.6.1187.2 when you specify --channel_dev=0 because channel_dev=0 means that "the current channel is stable".
