+## [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.
+- **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.
+- **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.
+- 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.
+- 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.
+
+### Fixes
+
+- Prevent stale lifecycle work, duplicate terminal events, and overlapping controls from deleting, reviving, or leaving the wrong download in a misleading state.
+- Keep missed completion events and connection-limit updates from leaving a finished or active download visually stuck.
+- Bound backend connection counts so user-selected limits are respected instead of allowing overlapping settings to exceed them.
+- Keep extension handoffs in the Add window and make selected-link batches retain their page context for folder suggestions.
+
+## [1.1.1] - 2026-07-17
+
+This patch release focuses on transfer reliability, browser captures, and easier download control.
+
+### New
+- Add YouTube playlist downloads with smoother queueing and scrolling for large playlists.
+- Add live per-download connection controls, clipboard capture for the Add window, and byte-level progress updates.
+
+### Improved
+- Recover slow or stalled transfers more reliably and apply connection defaults consistently, addressing [#19](https://github.com/nimbold/Firelink/issues/19) and [#20](https://github.com/nimbold/Firelink/issues/20).
+- Make pause, resume, retry, cancel, remove, and completion handling more consistent when actions or background events overlap.
+- Improve playlist state, media size estimates, and large-list performance.
+- Keep clipboard, browser, and deep-link handoffs behind the startup consent explanation, and make that boundary clearer.
+- Refresh bundled engines and dependencies while strengthening cross-platform package and diagnostic checks.
+
+### Fixed
+- Fix Gmail and other authenticated browser downloads that could lose their filename or save a sign-in page after a redirect, including Chrome Incognito, addressing [#21](https://github.com/nimbold/Firelink/issues/21).
+- Keep browser-capture metadata, cookies, and destinations tied to the correct download through redirects.
+- Prevent invalid URLs, late download events, stale progress, and abandoned media work from creating misleading rows or leftover temporary files.
+- Keep sensitive local paths, credentials, and persisted records protected in errors, diagnostics, and download state.

-## Why Firelink
+## Overview
 
-Firelink is a desktop download manager for fast transfers, browser capture, media extraction, scheduling, and clear file placement.
+Firelink manages direct downloads, browser captures, media extraction, playlists, scheduling, and file placement from one desktop app. It uses a Rust/Tauri backend with a React and TypeScript interface, and bundles the engines needed for its download and media workflows.
 
-It is now a cross-platform Rust/Tauri app with a React and TypeScript interface. A native backend coordinates downloads with aria2, yt-dlp, FFmpeg, Deno, and SQLite.
-
-The current desktop release is **1.1.0**, paired with Firelink Companion **2.0.4**.
-
-This stability-focused release adds a secure Windows portable build and strengthens queues, browser handoffs, media metadata, persistence, and packaged release checks.
+The current desktop release is **1.2.0**, paired with [Firelink Companion 2.0.6](https://github.com/nimbold/Firelink-Extension/releases). The release focuses on a more dependable download table and queue, better browser handoffs, broader localization, and safer packaged builds.

 ## Browser Extension
 
+[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.
+
+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.

-Firelink Companion sends browser links and downloads to the desktop app.
+Install the extension, open Firelink, and pair it from **Settings -> Integrations**. Use the latest [Firelink Companion 2.0.6 release](https://github.com/nimbold/Firelink-Extension/releases) with Firelink 1.2.0. Chromium users can load `firelink-chromium.zip` by following the [manual installation instructions](https://github.com/nimbold/Firelink-Extension#manual-chromium-installation).
 
-What it adds:
-
-- Automatic capture for regular browser downloads.
-- Explicit Fetch media actions from the popup and page context menu.
-- Context-menu actions for links and selected text.
-- Firefox and Chromium support.
-- Signed local requests using the token from **Settings -> Integrations**.
-- Fallback to the browser download when Firelink is closed or rejects a handoff.
-- Captured links always open Firelink's Add window before anything is added to the download list.
-
-Install the extension, open Firelink, then pair it from **Settings -> Integrations**. Firefox users can install from Mozilla Add-ons. Chromium users can use the [manual load-unpacked flow](https://github.com/nimbold/Firelink-Extension#manual-chromium-installation) with `firelink-chromium.zip` from the [extension releases](https://github.com/nimbold/Firelink-Extension/releases). Firelink Companion 2.0.4 is the matching extension release for Firelink 1.1.0.
-
-The extension lives in [Firelink-Extension](https://github.com/nimbold/Firelink-Extension). This repo also vendors it as the `Extensions/Browser` submodule.
