 # Release history
 
+### Aider v0.84.0
+
+- Added support for new Claude models including the Sonnet 4 and Opus 4 series (e.g., `claude-sonnet-4-20250514`,
+`claude-opus-4-20250514`) across various providers. The default `sonnet` and `opus` aliases were updated to these newer
+versions.
+- Added support for the `vertex_ai/gemini-2.5-flash-preview-05-20` model.
+- Fixed OpenRouter token cost calculation for improved accuracy.
+- Updated default OpenRouter models during onboarding to `deepseek/deepseek-r1:free` for the free tier and
+`anthropic/claude-sonnet-4` for paid tiers.
+- Automatically refresh GitHub Copilot tokens when used as OpenAI API keys, by Lih Chen.
+- Aider wrote 79% of the code in this release.
+
+### Aider v0.83.2
+
+- Bumped configargparse to 1.7.1 as 1.7 was pulled.
+- Added shell tab completion for file path arguments (by saviour) and for `--edit-format`/`--editor-edit-format` options.
+- Improved OpenRouter model metadata handling by introducing a local cache, increasing reliability and performance.
+- The `/settings` command now displays detailed metadata for active main, editor, and weak models.
+- Fixed an issue where files explicitly added via the command line were not correctly ignored if listed in `.gitignore`.
+- Improved automatic commit messages by providing more context during their generation, by wangboxue.
+
+### Aider v0.83.1
+
+- Improved user language detection by correctly normalizing hyphenated language codes (e.g., `en-US` to `en`) and enhancing the validation of locale results.
+- Prevented Aider from instructing the LLM to reply in 'C' or 'POSIX' when these are detected as the system locale.
+- Displayed a spinner with the model name when generating commit messages.
+
+### Aider v0.83.0
+
+- Added support for `gemini-2.5-pro-preview-05-06` models.
+- Added support for `qwen3-235b` models.
+- Added repo-map support for OCaml and OCaml interface files, by Andrey Popp.
+- Added a spinner animation while waiting for the LLM to start streaming its response.
+- Updated the spinner animation to a Knight Rider style.
+- Introduced `--attribute-co-authored-by` option to add co-author trailer to commit messages, by Andrew Grigorev.
+- Updated Gemini model aliases (e.g., `gemini`, `gemini-2.5-pro`) to point to the `05-06` preview versions.
+- Marked Gemini 2.5 Pro preview models as `overeager` by default.
+- Commit message prompt specifies the user's language.
+- Updated the default weak model for Gemini 2.5 Pro models to `gemini/gemini-2.5-flash-preview-04-17`.
+- Corrected `gemini-2.5-pro-exp-03-25` model settings to reflect its lack of support for `thinking_budget`.
+- Ensured model-specific system prompt prefixes are placed on a new line before the main system prompt.
+- Added tracking of total tokens sent and received, now included in benchmark statistics.
+- Automatically fetch model parameters (context window, pricing) for OpenRouter models directly from their website, by Stefan Hladnik.
+- Enabled support for `thinking_tokens` and `reasoning_effort` parameters for OpenRouter models.
+- Improved cost calculation using `litellm.completion_cost` where available.
+- Added model settings for `openrouter/google/gemini-2.5-pro-preview-03-25`.
+- Added `--disable-playwright` flag to prevent Playwright installation prompts and usage, by Andrew Grigorev.
+- The `aider scrape` command-line tool will now use Playwright for web scraping if it is available, by Jon Keys.
+- Fixed linter command execution on Windows by adopting `oslex` for argument quoting, by Titusz Pan.
+- Improved cross-platform display of shell commands by using `oslex` for robust argument quoting, by Titusz Pan.
+- Improved `/ask` mode to instruct the LLM to elide unchanging code in its responses.
+- Ensured web scraping in the GUI also respects Playwright availability and the `--disable-playwright` flag.
+- Improved display of filenames in the prompt header using rich Text formatting.
+- Enabled `reasoning_effort` for Gemini 2.5 Flash models.
+- Added a `--shell-completions` argument to generate shell completion scripts (e.g., for bash, zsh).
+- Explicit `--attribute-author` or `--attribute-committer` flags now override the default behavior when `--attribute-co-authored-by` is used, allowing finer control over commit attribution, by Andrew Grigorev.
+- Fixed an issue where read-only status of files might not be preserved correctly by some commands (e.g. `/drop` after adding a read-only file).
+- The `aider-args` utility (or `python -m aider.args`) now defaults to printing a sample YAML configuration if no arguments are provided.
+- Displayed token count progress and the name of the file or identifier being processed during repo map updates.
+- Extended the waiting spinner to also show for non-streaming responses and further enhanced its animation with console width clipping, cursor hiding, and a more continuous appearance.
+- Dropped support for Python 3.9.
+- Aider wrote 55% of the code in this release.
+
+### Aider v0.82.3
+
+- Add support for `gemini-2.5-flash-preview-04-17` models.
+- Improved robustness of edit block parsing when filenames start with backticks or fences.
+- Add new `udiff-simple` edit format, for Gemini 2.5 Pro.
+- Update default weak/editor models for Gemini 2.5 Pro models to use `gemini-2.5-flash-preview-04-17`.

+- Fix parsing of diffs for newly created files (`--- /dev/null`).
+- Add markdown syntax highlighting support when editing multi-line commit messages via `/commit`, by Kay Gosho.
+- Set Gemini 2.5 Pro models to use the `overeager` prompt setting by default.
+- Add common file types (`.svg`, `.pdf`) to the default list of ignored files for AI comment scanning (`--watch`).
+- Skip scanning files larger than 1MB for AI comments (`--watch`).
+
+### Aider v0.82.2
+
+- Fix editing shell files with diff-fenced, by zjy1412.
+- Improve robustness of patch application by allowing multiple update/delete actions for the same file within a single response.
+- Update prompts to instruct LLMs to consolidate all edits for a given file into a single block within the patch.

+
+        Attribution Logic:
+        ------------------
+        This method handles Git commit attribution based on configuration flags and whether
+        Aider generated the changes (`aider_edits`).
+
+        Key Concepts:
+        - Author: The person who originally wrote the code changes.
+        - Committer: The person who last applied the commit to the repository.
+        - aider_edits=True: Changes were generated by Aider (LLM).
+        - aider_edits=False: Commit is user-driven (e.g., /commit manually staged changes).
+        - Explicit Setting: A flag (--attribute-...) is set to True or False
+          via command line or config file.
+        - Implicit Default: A flag is not explicitly set, defaulting to None in args, which is
+          interpreted as True unless overridden by other logic.
+
+        Flags:
+        - --attribute-author: Modify Author name to "User Name (aider)".
+        - --attribute-committer: Modify Committer name to "User Name (aider)".
+        - --attribute-co-authored-by: Add
+          "Co-authored-by: aider (<model>) <noreply@aider.chat>" trailer to commit message.
+
+        Behavior Summary:
+
+        1. When aider_edits = True (AI Changes):
+           - If --attribute-co-authored-by=True:
+             - Co-authored-by trailer IS ADDED.
+             - Author/Committer names are NOT modified by default (co-authored-by takes precedence).
+             - EXCEPTION: If --attribute-author/--attribute-committer is EXPLICITLY True, the
+               respective name IS modified (explicit overrides precedence).
+           - If --attribute-co-authored-by=False:
+             - Co-authored-by trailer is NOT added.
+             - Author/Committer names ARE modified by default (implicit True).
+             - EXCEPTION: If --attribute-author/--attribute-committer is EXPLICITLY False,
+               the respective name is NOT modified.
+
+        2. When aider_edits = False (User Changes):
+           - --attribute-co-authored-by is IGNORED (trailer never added).
+           - Author name is NEVER modified (--attribute-author ignored).
+           - Committer name IS modified by default (implicit True, as Aider runs `git commit`).
+           - EXCEPTION: If --attribute-committer is EXPLICITLY False, the name is NOT modified.
+
+        Resulting Scenarios:
+        - Standard AI edit (defaults): Co-authored-by=False -> Author=You(aider),
+          Committer=You(aider)
+        - AI edit with Co-authored-by (default): Co-authored-by=True -> Author=You,
+          Committer=You, Trailer added
+        - AI edit with Co-authored-by + Explicit Author: Co-authored-by=True,
+          --attribute-author -> Author=You(aider), Committer=You, Trailer added
+        - User commit (defaults): aider_edits=False -> Author=You, Committer=You(aider)
+        - User commit with explicit no-committer: aider_edits=False,
+          --no-attribute-committer -> Author=You, Committer=You

+### Aider v0.84.0
+
+- Added support for new Claude models including the Sonnet 4 and Opus 4 series (e.g., `claude-sonnet-4-20250514`,
+`claude-opus-4-20250514`) across various providers. The default `sonnet` and `opus` aliases were updated to these newer
+versions.
+- Added support for the `vertex_ai/gemini-2.5-flash-preview-05-20` model.
+- Fixed OpenRouter token cost calculation for improved accuracy.
+- Updated default OpenRouter models during onboarding to `deepseek/deepseek-r1:free` for the free tier and
+`anthropic/claude-sonnet-4` for paid tiers.
+- Automatically refresh GitHub Copilot tokens when used as OpenAI API keys, by Lih Chen.
+- Aider wrote 79% of the code in this release.
+
+### Aider v0.83.2
+
+- Bumped configargparse to 1.7.1 as 1.7 was pulled.
+- Added shell tab completion for file path arguments (by saviour) and for `--edit-format`/`--editor-edit-format` options.
+- Improved OpenRouter model metadata handling by introducing a local cache, increasing reliability and performance.
+- The `/settings` command now displays detailed metadata for active main, editor, and weak models.
+- Fixed an issue where files explicitly added via the command line were not correctly ignored if listed in `.gitignore`.
+- Improved automatic commit messages by providing more context during their generation, by wangboxue.
+
+### Aider v0.83.1
+
+- Improved user language detection by correctly normalizing hyphenated language codes (e.g., `en-US` to `en`) and enhancing the validation of locale results.
+- Prevented Aider from instructing the LLM to reply in 'C' or 'POSIX' when these are detected as the system locale.
+- Displayed a spinner with the model name when generating commit messages.
+
+### Aider v0.83.0
+
+- Added support for `gemini-2.5-pro-preview-05-06` models.
+- Added support for `qwen3-235b` models.
+- Added repo-map support for OCaml and OCaml interface files, by Andrey Popp.
+- Added a spinner animation while waiting for the LLM to start streaming its response.
+- Updated the spinner animation to a Knight Rider style.
+- Introduced `--attribute-co-authored-by` option to add co-author trailer to commit messages, by Andrew Grigorev.
+- Updated Gemini model aliases (e.g., `gemini`, `gemini-2.5-pro`) to point to the `05-06` preview versions.
+- Marked Gemini 2.5 Pro preview models as `overeager` by default.
+- Commit message prompt specifies the user's language.
+- Updated the default weak model for Gemini 2.5 Pro models to `gemini/gemini-2.5-flash-preview-04-17`.
+- Corrected `gemini-2.5-pro-exp-03-25` model settings to reflect its lack of support for `thinking_budget`.
+- Ensured model-specific system prompt prefixes are placed on a new line before the main system prompt.
+- Added tracking of total tokens sent and received, now included in benchmark statistics.
+- Automatically fetch model parameters (context window, pricing) for OpenRouter models directly from their website, by Stefan Hladnik.
+- Enabled support for `thinking_tokens` and `reasoning_effort` parameters for OpenRouter models.
+- Improved cost calculation using `litellm.completion_cost` where available.
+- Added model settings for `openrouter/google/gemini-2.5-pro-preview-03-25`.
+- Added `--disable-playwright` flag to prevent Playwright installation prompts and usage, by Andrew Grigorev.
+- The `aider scrape` command-line tool will now use Playwright for web scraping if it is available, by Jon Keys.
+- Fixed linter command execution on Windows by adopting `oslex` for argument quoting, by Titusz Pan.
+- Improved cross-platform display of shell commands by using `oslex` for robust argument quoting, by Titusz Pan.
+- Improved `/ask` mode to instruct the LLM to elide unchanging code in its responses.
+- Ensured web scraping in the GUI also respects Playwright availability and the `--disable-playwright` flag.
+- Improved display of filenames in the prompt header using rich Text formatting.
+- Enabled `reasoning_effort` for Gemini 2.5 Flash models.
+- Added a `--shell-completions` argument to generate shell completion scripts (e.g., for bash, zsh).
+- Explicit `--attribute-author` or `--attribute-committer` flags now override the default behavior when `--attribute-co-authored-by` is used, allowing finer control over commit attribution, by Andrew Grigorev.
+- Fixed an issue where read-only status of files might not be preserved correctly by some commands (e.g. `/drop` after adding a read-only file).
+- The `aider-args` utility (or `python -m aider.args`) now defaults to printing a sample YAML configuration if no arguments are provided.
+- Displayed token count progress and the name of the file or identifier being processed during repo map updates.
+- Extended the waiting spinner to also show for non-streaming responses and further enhanced its animation with console width clipping, cursor hiding, and a more continuous appearance.
+- Dropped support for Python 3.9.
+- Aider wrote 55% of the code in this release.
+
+### Aider v0.82.3
+
+- Add support for `gemini-2.5-flash-preview-04-17` models.
+- Improved robustness of edit block parsing when filenames start with backticks or fences.
+- Add new `udiff-simple` edit format, for Gemini 2.5 Pro.
+- Update default weak/editor models for Gemini 2.5 Pro models to use `gemini-2.5-flash-preview-04-17`.
+- Instruct models to reply in the user's detected system language.
+- Fix parsing of diffs for newly created files (`--- /dev/null`).
+- Add markdown syntax highlighting support when editing multi-line commit messages via `/commit`, by Kay Gosho.
+- Set Gemini 2.5 Pro models to use the `overeager` prompt setting by default.
+- Add common file types (`.svg`, `.pdf`) to the default list of ignored files for AI comment scanning (`--watch`).
+- Skip scanning files larger than 1MB for AI comments (`--watch`).
+
+### Aider v0.82.2
+
+- Fix editing shell files with diff-fenced, by zjy1412.
+- Improve robustness of patch application by allowing multiple update/delete actions for the same file within a single response.
+- Update prompts to instruct LLMs to consolidate all edits for a given file into a single block within the patch.
+
 ### Aider v0.82.1

+# Gemini 2.5 Pro Preview 03-25 benchmark cost
+
+## Summary
+The $6.32 cost reported to run the aider polyglot benchmark on
+Gemini 2.5 Pro Preview 03-25 was incorrect.
+The true cost was higher, possibly significantly so.
+The incorrect cost has been removed from the leaderboard.
+
+An investigation determined the primary cause was that the litellm
+package (used by aider for LLM API connections) was not properly including reasoning tokens in 
+the token counts it reported.
+While an incorrect price-per-token entry for the model also existed in litellm's cost
+database at that time, this was found not to be a contributing factor.
+Aider's own internal, correct pricing data was utilized during the benchmark.
+
+## Resolution
+
+Litellm began correctly including reasoning tokens in the reported counts
+on April 21, 2025 in 
+commit [a7db0df](https://github.com/BerriAI/litellm/commit/a7db0df0434bfbac2b68ebe1c343b77955becb4b).
+This change was released in litellm v1.67.1.
+Aider picked up this change April 28, 2025 when it upgraded its litellm dependency 
+from v1.65.7 to v1.67.4.post1
+in commit [9351f37](https://github.com/Aider-AI/aider/commit/9351f37).
+That dependency change shipped on May 5, 2025 in aider v0.82.3.
+
+Unfortunately the 03-25 version of Gemini 2.5 Pro Preview is no longer available,
+so it is not possible to re-run the benchmark to obtain an accurate cost.
+As a possibly relevant comparison, the newer 05-06 version of Gemini 2.5 Pro Preview
+completed the benchmark at a cost of about $37.
+
+## Investigation detail
+
+The version of litellm available at that time of the benchmark appears to have been
+excluding reasoning tokens from the token counts it reported.
+So even though aider had correct per-token pricing, it did not have the correct token counts
+used during the benchmark.
+This resulted in an underestimate of the benchmark costs.
+
+The incorrect litellm database entry does not appear to have affected the aider benchmark costs.
+Aider maintains and uses its own database of costs for some models, and it contained
+the correct pricing at the time of the benchmark.
+Aider appears to have
+loaded the correct cost data from its database and made use of it during the benchmark.
+
+Every aider benchmark report contains the git commit hash of the aider repository state used to
+run the benchmark.
+The 
+[benchmark run in question](https://github.com/Aider-AI/aider/blob/edbfec0ce4e1fe86735c915cb425b0d8636edc32/aider/website/_data/polyglot_leaderboard.yml#L814)
+was built from 
+commit [0282574](https://github.com/Aider-AI/aider/commit/0282574).
+
+Additional runs of the benchmark from that build verified that the error in litellm's
+model cost database appears not to have been a factor:
+
+- Aider's internal model database correctly overrides the litellm database, which contained an incorrect token cost at the time.
+- The correct pricing is loaded from aider's internal model database and produces similar (incorrect) costs as the original run.
+- Updating aider's internal model database with an absurdly high token cost resulted in an appropriately high benchmark cost report, demonstrating that the internal database costs were in effect.
+
+This specific build of aider was then updated with various versions of litellm using `git biset`
+to identify the first litellm commit where reasoning tokens counts were correctly reported.

+# Qwen3 results on the aider polyglot benchmark
+
+As [previously discussed when Qwen2.5 was released](/2024/11/21/quantization.html),
+details matter when working with open source models for AI coding.
+Proprietary models are served by their creators or trusted providers with stable inference settings.
+Open source models are wonderful because anyone can serve them,
+but API providers can use very different inference settings, quantizations, etc.
+
+Below are collection of aider polyglot benchmark results for the new Qwen3 models.
+Results are presented using both "diff" and "whole" 
+[edit formats](https://aider.chat/docs/more/edit-formats.html),
+with various models settings, against various API providers.
+
+See details on the 
+[model settings](https://aider.chat/docs/config/adv-model-settings.html#model-settings) 
+used after the results table.
+
+{: .note }
+This article is being updated as new results become available.
+Also, some results were submitted by aider users and have not been verified.

+# GitHub Copilot
+
+Aider can connect to GitHub Copilot’s LLMs because Copilot exposes a standard **OpenAI-style**
+endpoint at:
+
+```
+https://api.githubcopilot.com
+```
+
+First, install aider:
+
+{% include install.md %}
+
+---
+
+## Configure your environment
+
+```bash
+# macOS/Linux
+export OPENAI_API_BASE=https://api.githubcopilot.com
+export OPENAI_API_KEY=<oauth_token>
+
+# Windows (PowerShell)
+setx OPENAI_API_BASE https://api.githubcopilot.com
+setx OPENAI_API_KEY  <oauth_token>
+# …restart the shell after setx commands
+```
+
+---
+
+### Where do I get the token?
+The easiest path is to sign in to Copilot from any JetBrains IDE (PyCharm, GoLand, etc).
+After you authenticate a file appears:
+
+```
+~/.config/github-copilot/apps.json
+```
+
+Copy the `oauth_token` value – that string is your `OPENAI_API_KEY`.
+
+*Note:* tokens created by the Neovim **copilot.lua** plugin (old `hosts.json`) sometimes lack the
+needed scopes. If you see “access to this endpoint is forbidden”, regenerate the token with a
+JetBrains IDE or the VS Code Copilot extension.
+
+---
+
+## Discover available models
+
+Copilot hosts many models (OpenAI, Anthropic, Google, etc).  
+List the models your subscription allows with:
+
+```bash
+curl -s https://api.githubcopilot.com/models \
+  -H "Authorization: Bearer $OPENAI_API_KEY" \
+  -H "Content-Type: application/json" \
+  -H "Copilot-Integration-Id: vscode-chat" | jq -r '.data[].id'
+```
+
+Each returned ID can be used with aider by **prefixing it with `openai/`**:
+
+```bash
+aider --model openai/gpt-4o
+# or
+aider --model openai/claude-3.7-sonnet-thought
+```
+
+---
+
+## Quick start
+
+```bash
+# change into your project
+cd /to/your/project
+
+# talk to Copilot
+aider --model openai/gpt-4o
+```
+
+---
+
+## Optional config file (`~/.aider.conf.yml`)
+
+```yaml
+openai-api-base: https://api.githubcopilot.com
+openai-api-key:  "<oauth_token>"
+model:           openai/gpt-4o
+weak-model:      openai/gpt-4o-mini
+show-model-warnings: false
+```
+
+---
+
+## FAQ
+
+* Calls made through aider are billed through your Copilot subscription  
+  (aider will still print *estimated* costs).
+* The Copilot docs explicitly allow third-party “agents” that hit this API – aider is playing by
+  the rules.
+* Aider talks directly to the REST endpoint—no web-UI scraping or browser automation.
