Warning

Review limit reached

@MichalFrends1, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 12 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

LocalBackup now treats file-mask regex characters as literals by default. The <regex> prefix enables regular-expression matching. Tests cover regex opt-in and exact filenames containing round or square brackets. The package version is 3.0.0.

Changes

LocalBackup mask matching

Layer / File(s)	Summary
Literal masks and explicit regex mode Frends.Files.LocalBackup/Frends.Files.LocalBackup/LocalBackup.cs, Frends.Files.LocalBackup/Frends.Files.LocalBackup/Definitions/Input.cs, Frends.Files.LocalBackup/Frends.Files.LocalBackup.Tests/UnitTests.cs, Frends.Files.LocalBackup/CHANGELOG.md, Frends.Files.LocalBackup/Frends.Files.LocalBackup/Frends.Files.LocalBackup.csproj	Wildcard masks now escape regex-special characters. Regex masks require the <regex> prefix. Documentation and release notes describe both modes. Tests cover regex masks and filenames containing brackets. The package version is 3.0.0.

Poem

A rabbit checked the backup trail,
Where brackets once could make it fail.
“Literal masks now keep their shape,
Regex waits behind its <regex> gate.”
Fresh tests hop by, files safe and bright.

- Around line 3-18: Update the 3.0.0 entry in the changelog by adding a ###
Changed section after ### Fixed and moving the default literal-mask semantics,
BREAKING CHANGE upgrade note, and all related <regex> migration examples into
it, leaving only the bracket-handling bug fix under ### Fixed.

In `@Frends.Files.LocalBackup/Frends.Files.LocalBackup/LocalBackup.cs`:
- Around line 162-164: Update the wildcard regex construction in the pattern
assignment to replace escaped `?` with `.` rather than `.+`, preserving the
documented one-character wildcard behavior while leaving `*` handling unchanged.
