chore(release): prepare Firelink 1.3.0

Keep native credential-store completion pending until the frontend accepts it, prevent stale grant races, and isolate blocking keyring work from the UI. Derive sidebar reveal spacing from each custom control style and restore neutral GNOME/minimal hover feedback.

CHANGELOG.md

@@ -5,26 +5,57 @@ All notable changes to Firelink will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.3.0] - 2026-07-29
+
+This release focuses on smoother queue control, a more comfortable interface, and safer recovery when downloads or browser handoffs are interrupted.
+
+### New features
+
+- **Live speed limits and connection controls** can be adjusted while a download is active.
+- **Queue reordering and bulk actions** are easier to use, with paused downloads kept behind work that is ready to run.
+- **Appearance preferences** now include a Windows 11-style option, sidebar-aware window controls, curated fonts for supported languages, and optional localized calendar dates. These improvements respond to [#31](https://github.com/nimbold/Firelink/issues/31).
+- **Firelink Companion `2.1.0`** is included in the `Extensions/Browser` submodule. Get the latest extension from the [Firelink-Extension releases](https://github.com/nimbold/Firelink-Extension/releases/latest).
+
+### Improvements
+
+- Resume, retry, pause, and redownload actions now recover more reliably when an earlier attempt has disappeared or a background event arrives late, addressing the failed-resume report in [#28](https://github.com/nimbold/Firelink/issues/28).
+- Browser captures recover more safely when Firelink is starting, the extension restarts, or capture settings change during handoff. Captures remain in the Add window for review.
+- macOS minimize and Dock, Spotlight, and Raycast reopen behavior are more consistent, addressing [#30](https://github.com/nimbold/Firelink/issues/30).
+- The downloads table stays readable at narrow widths: row actions remain contained, columns resize consistently, and controls no longer cover Date Added text, addressing [#32](https://github.com/nimbold/Firelink/issues/32).
+- Add-window metadata, duplicate resolution, playlist selection, floating menus, page navigation, and table interactions provide clearer feedback and better keyboard behavior.
+- Startup consent and keychain access are more predictable, with clearer permission feedback and safer modal focus.
+
+### Fixes
+
+- Prevent stale pause, resume, retry, completion, and remove actions from reviving a download, reporting the wrong result, or leaving a row stuck in a misleading state.
+- Keep queue limits, connection recovery, missing completion events, and retry cleanup from leaving downloads stranded or exceeding the user’s settings.
+- Keep paused work behind pending downloads and make queue controls behave correctly when several actions happen close together.
+- Refresh dependencies and bundled engines, and strengthen release, package, portable-mode, and cross-platform verification.
+
+### Known limitation
+
+- Very long media-generated filenames can still exceed an operating system’s filename limit. For [#29](https://github.com/nimbold/Firelink/issues/29), the current workaround is to shorten the filename in **Properties** before starting the download.
+
 ## [1.2.0] - 2026-07-22
 
 This release makes everyday download management easier to organize, review, and trust across the desktop app and browser extension.
 
 ### New features
 
-- **Localized desktop interface** for Persian, Hebrew, Russian, Ukrainian, and Simplified Chinese, including RTL layouts. These translations are currently produced with help from LLMs and need user review; please report corrections so they can improve.
+- **Localized desktop interface** for Persian, Hebrew, Russian, Ukrainian, and Simplified Chinese, responding to the Chinese-language request in [#17](https://github.com/nimbold/Firelink/issues/17). These translations are currently produced with help from LLMs and need user review; please report corrections so they can improve.
 - **Customizable download table** with selectable columns, drag-to-reorder controls, sorting, clearer size alignment, and better bulk actions.
 - **Optional batch folders** for multi-link downloads, addressing [#27](https://github.com/nimbold/Firelink/issues/27). Firelink can suggest an editable folder name from the page title or common filename while keeping the existing category-based behavior as the default.
-- **Remember the last Add-window directory**, with an opt-in setting so users remain in control of where it applies.
-- **Per-download connection controls** for normal and media transfers, with the active aria2 connection count shown in the download table.
+- **Remember the last Add-window directory**, with an opt-in setting so users remain in control of where it applies, addressing [#23](https://github.com/nimbold/Firelink/issues/23).
+- **Per-download connection controls** for normal and media transfers, with the active aria2 connection count shown in the download table. This also follows the connection-setting report in [#20](https://github.com/nimbold/Firelink/issues/20).
 - **Latest Firelink Companion 2.0.6** in the `Extensions/Browser` submodule, including selected-link batch context and safer automatic capture recovery.
 
 ### Improvements
 
 - Make pause, resume, retry, remove, redownload, queue, scheduler, and settings actions safer when several operations overlap or background events arrive late.
-- Reuse unfinished downloads when their filenames match, while reducing the chance of stale state creating duplicate or misleading rows.
+- Reuse unfinished downloads when their filenames match, addressing [#26](https://github.com/nimbold/Firelink/issues/26), while reducing the chance of stale state creating duplicate or misleading rows.
 - Improve first-open navigation, lazy page loading, table layout, drag interactions, sorting, and window-control placement.
 - Improve RTL behavior while keeping the download table's physical file columns readable.
-- Handle locked browser cookie databases more gracefully and keep browser metadata and authenticated captures on the correct path.
+- Handle locked browser cookie databases more gracefully and keep browser metadata and authenticated captures on the correct path, addressing the media reports in [#22](https://github.com/nimbold/Firelink/issues/22) and [#24](https://github.com/nimbold/Firelink/issues/24).
 - Enforce startup consent before accessing saved credentials and make keychain-related startup behavior more predictable.
 - Refresh dependencies and bundled engines, and strengthen checks for macOS, Windows portable, Linux packages, release assets, and release version identity.
 - Refine localized wording, including Persian status labels.

 <summary><strong>Windows portable ZIP notes</strong></summary>
 
-The portable ZIP is a secondary distribution. Extract it to a writable folder and launch `firelink.exe`:
-
-- Keep it out of `Program Files`, read-only media, and folders that block SQLite or WebView writes.
-- Settings, queues, logs, and WebView data stay beside the executable under `data/`.
-- Close Firelink before moving or copying the folder, and close the installed app before launching the portable copy.
-- Credentials, browser cookies, and URL query or fragment data are not saved in portable queue records.
-- Saved site passwords remain in the Windows credential store and are not copied into the archive.
-- The folder contains the extension pairing credential. Treat it as sensitive and do not share it.
-- Saved absolute download locations may need to be selected again after moving the folder to another drive.
+- Keep the folder writable. Avoid `Program Files` and read-only media.
+- Settings, queues, logs, and WebView data are stored beside the executable in `data/`.
+- Close Firelink before moving or copying the folder.

+## Browser integration
 
-[Firelink Companion](https://github.com/nimbold/Firelink-Extension) connects browser downloads, links, and media pages to Firelink. Captured downloads always open Firelink's Add window so you can review them before starting or queuing them.
+[Firelink Companion `2.1.0`](https://github.com/nimbold/Firelink-Extension/releases/tag/v2.1.0) connects browser downloads, links, and media pages to Firelink. Use the latest Companion release with the latest Firelink release.
 
-It provides automatic capture for regular downloads, explicit **Fetch media** actions, link and selected-text context menus, Firefox and Chromium support, signed local requests, and a safe browser fallback when Firelink is unavailable.
+Captured links open Firelink's Add window for review before they are started or queued.
