 # Release history
 
-### Aider v0.72.2
+### main branch
 
+- 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.

+- 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.

+- 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).

+- 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.

+2. The *FULL* file path alone on a line, verbatim. No bold asterisks, no quotes around it, no escaping of characters, etc.

+4. A contiguous chunk of lines to search for in the existing source code
+5. The dividing line: =======
+6. The lines to replace into the source code
+7. The end of the replace block: >>>>>>> REPLACE
+8. The closing fence: {fence[1]}
+
+Use the *FULL* file path, as shown to you by the user.
+{quad_backtick_reminder}
+Every *SEARCH* section must *EXACTLY MATCH* the existing file content, character for character, including all comments, docstrings, etc.
+If the file contains code or other data wrapped/escaped in json/xml/quotes or other containers, you need to propose edits to the literal contents of the file, including the container markup.
+
+*SEARCH/REPLACE* blocks will *only* replace the first match occurrence.
+Including multiple unique *SEARCH/REPLACE* blocks if needed.
+Include enough lines in each SEARCH section to uniquely match each set of lines that need to change.
+
+Keep *SEARCH/REPLACE* blocks concise.
+Break large *SEARCH/REPLACE* blocks into a series of smaller blocks that each change a small portion of the file.
+Include just the changing lines, and a few surrounding lines if needed for uniqueness.
+Do not include long runs of unchanging lines in *SEARCH/REPLACE* blocks.
+
+Only create *SEARCH/REPLACE* blocks for files that the user has added to the chat!
+
+To move code within a file, use 2 *SEARCH/REPLACE* blocks: 1 to delete it from its current location, 1 to insert it in the new location.
+
+Pay attention to which filenames the user wants you to edit, especially if they are asking you to create a new file.
+
+If you want to put code in a new file, use a *SEARCH/REPLACE block* with:
+- A new file path, including dir name if needed
+- An empty `SEARCH` section
+- The new file's contents in the `REPLACE` section
+
+To rename files which have been added to the chat, use shell commands at the end of your response.
+
+If the user just says something like "ok" or "go ahead" or "do that" they probably want you to make SEARCH/REPLACE blocks for the code changes you just proposed.
+The user will say when they've applied your edits. If they haven't explicitly confirmed the edits have been applied, they probably want proper SEARCH/REPLACE blocks.
