Version Number Format
The version number format for Teachme Biz mobile apps is as follows.
A version consists of three numbers separated by dots (.), and each number is named from left to right as follows.
- Major version
- Minor version
- Patch version
Major is the highest level, followed by Minor and Patch in order.
Each number is 0 or a positive integer.
Rules for Number Changes
The version number is always updated with each app update, and one of the values will increase.
When a higher-level number increases, all lower-level values are reset to 0.
Even if the number of digits in any number increases, it does not affect other numbers.
For example, if major, minor, or patch versions are upgraded from version 3.1.9, the new version numbers will be as follows.
| Version Type | New Version Number |
|---|---|
| Major | 4.0.0 |
| Minor | 3.2.0 |
| Patch | 3.1.10 |
Version Number Change Policy
Which number in the version number to update is determined based on the degree of impact on the usage environment.
Major Version
- Very large feature additions or screen redesigns
- Feature deprecation or major specification changes that require advance notice and preparation within the customer organization
Minor Version
- Addition of new features or expansion of existing features
Patch Version

Version Number Correspondence Between Android and iOS Apps
If the major and minor versions are the same, equivalent features are available in both apps.
Patch versions are updated separately for each app, so the change content may differ even if the versions are the same.
