MUST

[XML] Remove string attrribute from views. There is a script on https://bugs.tryton.org/msg26170 to replace them.

Should

[SQL] Language codes have been simplified. If you want to keep custom translation you must update translation code to match the new code.
Here is an example for the code change from en_US to en:

UPDATE ir_translation SET lang = 'en' WHERE lang = 'en_US';

The ir_configuration may also contain language code:

UPDATE ir_configuration SET language = 'en' WHERE language = 'en_US';

You could also rename existing po file to match the new code.

Please consider making the migration queries for ir_translation and ir_configuration a MUST, as without them, posting invoices from version 5 results in an error.

[Must]
[trytond configuration file] the default language must be updated in order to use the short/simplified language code.
Otherwise this issue can be encountered (while using Invoice report):
