Echo v5 is maintenance release with major breaking changes

• Context is now struct instead of interface and we can add method to it in the future in minor versions.
• Adds new Router interface for possible new routing implementations.
• Drops old logging interface and uses moderm log/slog instead.
• Rearranges alot of methods/function signatures to make them more consistent.

Upgrade notes and v4 support:

• Echo v4 is supported with security* updates and bug fixes until 2026-12-31
• If you are using Echo in a production environment, it is recommended to wait until after 2026-03-31 before upgrading.
• Until 2026-03-31, any critical issues requiring breaking v5 API changes will be addressed, even if this violates semantic versioning.

See API_CHANGES_V5.md for public API changes between v4 and v5, notes on upgrading.

Upgrading TLDR:

If you are using Linux you can migrate easier parts like that:

find . -type f -name "*.go" -exec sed -i 's/ echo.Context/ *echo.Context/g' {} +
find . -type f -name "*.go" -exec sed -i 's/echo\/v4/echo\/v5/g' {} +

macOS

find . -type f -name "*.go" -exec sed -i '' 's/ echo.Context/ *echo.Context/g' {} +
find . -type f -name "*.go" -exec sed -i '' 's/echo\/v4/echo\/v5/g' {} +

or in your favorite IDE

Replace all:

1. echo.Context -> *echo.Context
2. echo/v4 -> echo/v5

This should solve most of the issues. Probably the hardest part is updating all the tests.
