Config breaking changes

In this release we introduced a few breaking changes to backend configurations. If you have only been using OpenHands via frontend (web GUI), nothing needs to be taken care of.

Here's a list of breaking changes in configs. They only apply to users who use OpenHands CLI via main.py. For more detail, see #2756.

Removal of --model-name option from main.py

Please note that --model-name, or -m option, no longer exists. You should set up the LLM configs in config.toml or via environmental variables.

LLM config groups must be subgroups of 'llm'

Prior to release 0.8, you can use arbitrary name for llm config in config.toml, e.g.

[gpt-4o]
model="gpt-4o"
api_key="<your_api_key>"

and then use --llm-config CLI argument to specify the desired LLM config group by name. This no longer works. Instead, the config group must be under llm group, e.g.:

[llm.gpt-4o]
model="gpt-4o"
api_key="<your_api_key>"

If you have a config group named llm, no need to change it, it will be used as the default LLM config group.

'agent' group no longer contains 'name' field

Prior to release 0.8, you may or may not have a config group named agent that looks like this:

[agent]
name="CodeActAgent"
memory_max_threads=2

Note the name field is now removed. Instead, you should put default_agent field under core group, e.g.

[core]
# other configs
default_agent='CodeActAgent'

[agent]
llm_config='llm'
memory_max_threads=2

[agent.CodeActAgent]
llm_config='gpt-4o'

Note that similar to llm subgroups, you can also define agent subgroups. Moreover, an agent can be associated with a specific LLM config group. For more detail, see the examples in config.template.toml.
