The short answer is, no. The long answer; you do not have to wait for an update to start using the translation you added or updated. To start using your translation immediately:
- Download and install Poedit.
- After you install Poedit you need to make a settings change which only needs to be done once.
- You need to setup Poedit to always compile the MO file when saving.
- Do do this, click the File → Preferences and on the Editor tab check the Automatically compile .mo file on save box.
- Go to the Connections Project page in Transifiex.
- Click the language you just added or updated.
- Click the POT File link. This will open up a pop-up window.
- Click the Download for use link. This will open up a window where you can choose where to save your translation. I suggest saving it to your Desktop so it is easy to find.
- Open the file you downloaded in Poedit.
- After you open the PO file, you only need to click the Save button.
- Go to where you saved the PO file you originally downloaded, you should now see a MO file.
- The MO and PO files needs to be named exactly using this format: connections-lang_COUNTRY.mo and connections-lang_COUNTRY.po. Here are few examples:
- Spanish connections-es_ES.mo and connections-es_ES.po
- French connections-fr_FR.mo and connections-fr_FR.po
- German connections-de_DE.mo and connections-de_DE.po
- Lastly, upload both the MO and PO file to your WordPress installation languages folder. This folder should be in the wp-content folder. If it does not exist, create it. For more details, please see this FAQ.
