EoL

EOL, or end of life, is a term used in product management and software development to indicate that a product, version, or service is no longer sold or officially supported by the vendor. When a product reaches EOL, vendors typically stop providing new updates, security patches, or technical assistance, and related services or components may be discontinued. Organizations are advised to migrate to a supported alternative before the end-of-life date. EOL planning is a part of risk management, software asset management, and compliance. Some vendors distinguish between end of life (no longer sold) and end of support (no longer receives updates), and may offer extended support for a fee.

End-of-Line, abbreviated EOL, refers to the character or sequence that marks the end of a line in a text file. Different operating systems use different conventions: Unix-like systems use a line feed (LF); Windows uses a carriage return followed by a line feed (CRLF); classic Mac OS used a carriage return (CR). Mixed line endings can cause problems in editors, version control, and build pipelines. Remedies include standardizing line endings across a project, configuring version control and editors to enforce a chosen convention, and using conversion tools when importing or sharing text files. Documenting the project’s line-ending policy helps avoid cross-platform issues.
