2024-08-30: Internationalization support for the UI

There is now an optional feature to enable a language picker in the UI:
https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/deploy_features.md#enabling-language-picker
This will change the language of UI messages, but not affect anything about the LLM system prompt.

Screenshot: 

As a result of this PR, all text messages for the UI are now in single files, per language, and all messages can be edited in one place. See guide here: https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/customization.md#customizing-the-ui

What's Changed

• Reduce JS size by using more specific import for react-syntax-highlighter by @pamelafox in #1947
• Send down LLM messages as dictionaries in thought process by @pamelafox in #1948
• Frontend multi-language support #1690 by @bnodir in #1790

New Contributors

• @bnodir made their first contribution in #1790

2024-08-23: Optional speech output is now on-demand

We previously would proactively load the speech output URLs when that feature was enabled. However, we received feedback that the proactive loading was wasteful. We now load only when the user clicks the speech icon, so the user will see a brief loading icon and then hear the speech play.

What's Changed

• On Demand Azure Speech Generation by @john0isaac in #1894
• Allow disabling app services auth by @mattgotteiner in #1932
• Bump the python-requirements group across 1 directory with 16 updates by @dependabot in #1924

Full Changelog: 2024-08-21...2024-08-23

2024-08-21: Markdown rendering for responses

The UI now supports rendering markdown syntax (including tables). Given that, we've removed the line from the default system prompt that said "Do not return markdown". If you want even more Markdown in responses, you may want to experiment with adding a line like "Please use Markdown to format lists, tables, headings, and emphasis."
Let us know if you have any issues with the rendering in the issue tracker.

What's Changed

• Add Markdown Render Support to GPT completions by @praveen-palanisamy in #56

2024-08-20: Default search service SKU to basic

The significant change in this release is that the infrastructure now defaults to the basic tier. This reduces the costs for new developers experimenting with this repo. However, if you pull the changes into an existing deployment with the standard tier, you'll get an error when it tries to provision the search service. You should explicitly set the search service SKU with this command first:

azd env set AZURE_SEARCH_SERVICE_SKU standard

This release also includes a few bug fixes.

What's Changed

• Better handling of auth errors by @pamelafox in #1879
• Prevent IME-related accidental message submission on Enter key press by @KanchiShimono in #1908
• Bump @fluentui/react-components from 9.37.3 to 9.54.13 in /app/frontend by @dependabot in #1918
• Bump aiohttp from 3.10.1 to 3.10.2 in /app/backend by @dependabot in #1921
• Reduce cost by defaulting to basic tier of search service by @pamelafox in #1925

2024-08-08: GPT-4o-mini support

This release includes support for gpt-4o-mini for the chat completion requests. This support required an update to the token counting package. See instructions for switching here:
https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/deploy_features.md#using-gpt-4
Unfortunately, gpt-4o-mini is only in eastus, so you may need to change the location of your OpenAI resource. You can change that in .azure/ENV-NAME/config.json

What's Changed

• Upgrade openai, openai-messages-token-helper, for gpt-4o-mini support by @dependabot in #1893

Full Changelog: 2024-08-07...2024-08-08

2024-07-22: Removal of VM from private network deployment

We previously included Bicep to enable the creation of a VM and Bastion for connection to a privately deployed app endpoint. However, due to security concerns around the VM enabling access to the endpoint, we've removed that option from deployment. To access the endpoint, you can instead use an Azure VPN gateway, Azure Virtual Desktop, other means of accessing the VNet, or add an allowance for your IP to the chat app's firewall.

2024-07-16: Seed parameter, Azure Verified Modules

This release includes:

• the addition of a seed parameter. That is particularly helpful if you are evaluating your app.
• a partial migration to Azure Verified Modules to reduce the amount of custom Bicep in this repo and inherit security best practices automatically. We will continue to migrate as many modules as possible.
• an improvement to the prepdocs script so that you can pass "--removeall" and "--remove" on the CLI. You still need to modify the script to specify the filename, however.
• a fix for the local frontend server, to address an issue with running "npm run dev" inside Dev Containers
