Release Notes¶

mimeogram 1.6 (2026-02-18)¶

Acquisition: Use Detextive 3.1 decode_inform for MIME type, charset, and line-separator detection, including BOM-aware UTF-8 charset reporting for round trips.
Add Python 3.14 and PyPy 3.11 support.
CLI: Add –no-ignores flag to disable gitignore filtering during file collection. When gitignore filtering is enabled (default), warnings are emitted for skipped files with guidance to use –no-ignores flag.
Integrate Detextive 2.0 for MIME type and charset detection, replacing internal detection with standardized library. This may produce normalized charset names (e.g., ‘iso8859-9’ instead of ‘iso-8859-9’) and treats empty files as valid text.
Packaging: Publish Linux aarch64 standalone executables in GitHub releases.

CLI: Disallow explicit None values for optional boolean flags and show {True,False} choices in help text.
CLI: Fix parser error that prevented the application from running.
CLI: Fix version command to work without requiring –application.name argument.
CLI: Prevent Linux/X11 clipboard operations from hanging when xclip forks to the background.

Add deterministic boundary option for reproducible mimeogram output. When enabled via --deterministic-boundary CLI flag or deterministic-boundary configuration setting, boundaries are generated from content hashes instead of random UUIDs, making output diff-friendly for version control workflows. (Feature request from @developingjames.)
Call finalize_module instead of reclassify_modules to improve documentation by applying Dynadoc to it.

Replace call to reclassify_modules with finalize_module to address deprecation warning.

Internals update - nothing to see here. Lock versions of some dependencies in anticipation of breaking changes.

Character set decoding error was raised when unable to detect line separator. Now, a warning is issued and the OS-native line separator is assumed.
Release 1.1 executables were broken due to incomplete bundling of tiktoken dependencies. Completely bundle these. (Bug report from @wad11656.)

Ignore macOS .DS_Store file, regardless of whether it is listed in .gitignore or whether there is a .gitignore when collecting files from a directory.

Likewise, ignore .env when collecting files from a directory. (For security reasons, as there may be secrets in it.)

One can still explicitly specify ignored files to include them in mimeograms. Ignoring only applies to collecting files from directories, when directories are given as arguments to mimeogram create.

Support reporting of total token counts for mimeograms as part of mimeogram create output.

Add Git ignore rule integration to avoid processing unwanted files.
Add mimeogram apply command with interactive review, hunk selection, file editing, and atomic file updates.
Add mimeogram create command for bundling files into clipboard-ready documents with preserved directory structure, Git ignore rule support, and integrated message editing.
Add mimeogram provide-prompt command for generating format instructions and setting up LLM project-level support.
Add atomic file updates with automatic rollback on errors.
Add filesystem protection system to prevent accidental modification of sensitive paths.
