We keep a ChangeLog, please read it before upgrading.

Ihatemoney follows semantic versioning. So minor/patch upgrades can be applied blindly.

General procedure

(sufficient for minor/patch upgrades)

  1. From the virtual environment (if any):

    pip install -U ihatemoney
  2. Restart supervisor, or Apache, depending on your setup.

You may also want to set new configuration variables (if any). They are mentioned in the ChangeLog, but this is not required for minor/patch upgrades, a safe default will be used automatically.

Version-specific instructions

(must read for major upgrades)

When upgrading from a major version to another, you must follow special instructions:

4.x → 5.x

Switch to a supported version of Python


If you are already using Python ≥ 3.7, you can skip this section, no special action is required.

If you were running IHateMoney using Python < 3.7, you must, before upgrading:

  1. Ensure to have a Python ≥ 3.7 available on your system

  2. Rebuild your virtual environment (if any). It will not alter your database nor configuration. For example, if your virtual environment is in /home/john/ihatemoney/:

    rm -rf /home/john/ihatemoney
    pyhton3 -m venv /home/john/ihatemoney
    source /home/john/ihatemoney/bin/activate

You might need to pip install additional dependencies if you are using one or several of the following deployment options :

  • Gunicorn (Nginx)

  • MariaDB

  • PostgreSQL

If so, pick the pip commands to use in the relevant section(s) of installation.

Then follow General procedure from step 1 in order to complete the update.

Switch to MariaDB >= 10.3.2 instead of MySQL


If you are using SQLite or PostgreSQL, you can skip this section, no special action is required.

If you were running IHateMoney with MySQL, you must switch to MariaDB. MySQL is no longer a supported database option.

In addition, the minimum supported version of MariaDB is 10.3.2. See this MySQL / MariaDB issue for details.

To upgrade:

  1. Ensure you have a MariaDB server installed and configured, and that its version is at least 10.3.2.

  2. Copy your database from MySQL to MariaDB.

  3. Ensure that IHateMoney is correctly configured to use your MariaDB database, see SQLALCHEMY_DATABASE_URI

Then follow General procedure from step 1 in order to complete the update.

2.x → 3.x

Sentry support has been removed. Sorry if you used it.

Appart from that, General procedure applies.

1.x → 2.x

Switch from git installation to pip installation

The recommended installation method is now using pip. Git is now intended for development only.


Be extra careful to not remove your sqlite database nor your settings file, if they are stored inside the cloned folder.

  1. Delete the cloned folder


If you are using a virtual environment, then the following commands should be run inside it (see Prepare virtual environment (recommended)).

  1. Install ihatemoney with pip:

    pip install ihatemoney
  2. Fix your configuration file (paths have changed), depending on the software you use in your setup:

    • gunicorn: ihatemoney generate-config gunicorn.conf.py (nothing critical changed, keeping your old config might be fine)

    • supervisor : ihatemoney generate-config supervisord.conf (mind the command= line)

    • apache: ihatemoney generate-config apache-vhost.conf (mind the WSGIDaemonProcess, WSGIScriptAlias and Alias lines)

  3. Restart Apache or Supervisor, depending on your setup.

Upgrade ADMIN_PASSWORD to its hashed form


Not required if you are not using the ADMIN_PASSWORD feature.

ihatemoney generate_password_hash will do the hashing job for you, just put its result in the ADMIN_PASSWORD var from your ihatemoney.cfg and restart apache or the supervisor job.
