GpgFrontend: baixar versions anteriors

v2.2.3 is recommended for all users. It is a drop-in upgrade from 2.2.2：your profiles, keys and settings carry over unchanged.

### What's new

• **Email module reworked.** Send signed and encrypted mail over SMTP and read your mailboxes over IMAP, with a smoother workflow from writing to sending and a clearer view of which parts of each message are signed or encrypted.
• **OpenPGP Structure Inspector** shows what is inside any message, key or signature.
• **Profile packages are truly cross-platform.** Export on one operating system and open on any other, with your key databases working. Machine-specific settings stay behind.
• **Key database changes apply right away,** with no restart.
• **Temporary profiles** that are deleted completely when you close their window.
• **Right-to-left text** is detected automatically. (#268)
• **Simpler toolbar.** Encrypt and Decrypt variants share one button each.
• **Redesigned key group management.**
• **New languages:** Polish (thanks to Ralts) and Turkish (thanks to @cerob, #273).

### Security and structural improvements

• **Module system rewritten.** Modules are signed packages, checked before they load, and can only use the features they declare. Third-party modules run only after you approve them. Modules can now add their own menus, tabs, views and settings pages, and the module manager shows which modules were refused and why.
• **Profile packages rebuilt.** Exported profiles always need a passphrase, damaged or tampered packages are detected, and opening one leaves no unencrypted copy on disk.
• **Secrets handled more carefully.** Passphrases are wiped from memory after use, and cached passphrases are kept separate for each key database.
• **No partial or unverified output.** Decrypted files and archives are written only after the integrity check passes, so you never get a half-written or tampered result. A failed or cancelled operation leaves nothing behind.
• **Harder to encrypt to the wrong people.** An optional single-recipient mode stops old checkmarks from adding extra recipients, and you can choose to confirm before encrypting to more than one person. When encryption is not possible, you are told which key is the problem and why.
• **Up-to-date OpenPGP.** Post-quantum encryption now follows the final standard (RFC 9980), and you are warned before mixing post-quantum and classical recipients. Keys and signatures are checked more strictly, and signatures made by keys that are not allowed to sign are shown as such.

### Fixes

• Unsaved text is no longer lost when you quit.
• Content signed by someone whose public key you don't have now decrypts, with a warning that the signature couldn't be checked. (#271)
• The system keychain asks to be unlocked after a reboot instead of showing an error. (#267)
• Windows：importing post-quantum private subkeys works again (bundled GnuPG 2.5.21). (#266)
• The rPGP engine now decrypts files of any size using little memory. (#272)
• Fixed several crashes when closing windows and quitting.

> [!IMPORTANT]
> **Module developers:** modules built for 2.2.2 or earlier will not load. Rebuild against the new SDK, then package and sign with the module packager.
>
> **Qt5 is no longer supported in 2.2.x.** Starting with 2.2.3, GpgFrontend requires Qt 6.5 or newer. If you need Qt5, stay on the 2.1.x series, which still supports it.

**Full Changelog**：https://github.com/saturneric/GpgFrontend/compare/v2.2.2...v2.2.3

v2.2.2 continues the 2.2.x series and is recommended for all users. Upgrading from 2.2.1 is a drop-in replacement: existing key databases and settings are migrated automatically.

### Highlights

**Profiles.** Maintain several independent setups, each with its own key databases, settings, and secure key, and switch between them from the new Profile menu.
**Portable profile packages (`.gfp`).** Export an entire profile into a single passphrase-encrypted file and open it anywhere with a double-click. It runs as a temporary profile that leaves nothing behind and asks on close whether to save your changes back into the package.
**Instant Messaging Steganography.** Encrypt and sign a message into a single Base58 word that survives being pasted into any chat app. Tokens carry no visible marker: whitened with a shared password book, they look like random text to anyone who does not have the same book phrase. The book phrase itself is now stored encrypted and can be generated and fingerprinted from settings.
**Key categories and a better key list.** Coloured, reorderable category tabs replace the old favourites list. The key list also gains Status and Expire Date columns with a configurable expiry warning, plus search and sorting, and it remembers column widths and checked keys across restarts.
**More control over keys.** Change the passphrase of a single subkey, pin which encryption subkey is used for a recipient, export keys to a location of your choice, start a keyserver search from the selected key, and see at a glance whether a key is v4, v5, or v6.
**Move a key to a smart card,** powered by a rebuilt smart card controller and a dedicated card picker.
**A refreshed interface.** Settings are now a searchable sidebar with new rPGP and Advanced pages, and with room for pages provided by modules. The file browser gains a breadcrumb path bar and OpenPGP badges, the module controller has been redesigned, appearance changes apply instantly, and the setup wizard can switch languages on the spot.

### Security

**Application key protection.** Choose between no protection, the system keychain, or a PIN, backed by the macOS Keychain, the Windows Credential Manager, or libsecret. A Change PIN action is included, along with a reset path in case you forget it.
**rPGP: forged self-signatures are rejected.** Revocations, expiry dates, and key capabilities are only honoured when their self-signature verifies, so a forged revocation can no longer be attached to a key.
**rPGP: weak and hostile inputs are refused.** MD5, SHA-1, and RIPEMD-160 are never accepted as valid, cleartext signing is pinned to SHA-512, unauthenticated SED packets are rejected before decryption, and compression bombs are bounded.
**rPGP: weak key generation removed.** RSA below 2048 bits and DSA are no longer offered, as required by RFC 9580. Existing keys keep working, and GnuPG is unaffected.
**Archive extraction hardened** against path traversal, symlinks, oversized contents, and setuid bits. User ID validation is also stricter.

### Engines

**rPGP: key expiration management,** plus interoperability fixes for v6 messages, expiry handling, revoked primary keys, and signer attribution. All of this is verified against `sq` and GnuPG using an RFC 9580 test corpus that now ships with the test suite.
**GnuPG: connections recover properly.** Failed connection attempts back off instead of re-probing on every operation, overly long home paths produce a clear error instead of failing opaquely, and a missing `gpgconf` falls back to rPGP rather than refusing to start.
**GnuPG: maintenance actions** in settings let you clear the password cache, reload the configuration, and restart gpg-agent, with real error messages replacing generic failures and correct smart card serial validation.

> [!IMPORTANT]
> **AppImage users: check which file you download.** The portable build is now a separate download: pick the AppImage with `portable` in its name, or any other one for the normal version.

## Improvements & Fixes

- Enhanced built-in text editor with line numbers, current-line highlighting, richer status
information, and more reliable document recovery.
- Improved file panel usability, including drag-and-drop operations, file/folder creation, Trash
support, and better navigation.
- Refreshed startup wizard and onboarding experience.
- Appearance changes now take effect immediately without restarting.
- Improved window restoration and multi-screen behavior.
- Improved key generation workflows and algorithm selection.
- Enhanced key database management dialogs and interactions.
- Improved output filename handling for encryption, decryption, signing, and verification operations.
- Fixed potential crashes (AppImage) caused by conflicts between project-built OpenSSL and Qt’s
OpenSSL usage.
- Fixed editor recovery and tab restoration issues.
- Various UI and stability fixes.

## Localization

- Added Russian language support. (#249)
- Completed many previously missing translations across supported languages using automated
translation and automated review.
- Translation quality may still need community refinement. If you notice inaccurate or unnatural
translations, contributions are welcome.

## Build & Signing

- Added build coverage for macOS 16 Intel environments.
- No longer uses a project-built OpenSSL in official builds and now relies on the system OpenSSL
provided by the target environment. Downstream packagers should make sure OpenSSL is provided by
the system or packaging environment.
- This is the final release signed with the Windows code signing certificate serial
785a00b7985a7078fb1913c7b93b05e6. A new signing certificate will be used starting from the next
release.

> [!NOTE]
>
> Many improvements in this release were synchronized from the main branch. For the 2.1 maintenance
> series, only UI enhancements and bug fixes have been backported. No major core functionality changes
> are included.

Important Notes
System Requirements Clarification: My strategy is to extend support to the most prevalent versions across various platforms. Unmaintained or obsolete platform versions will gradually be excluded from my support commitment. This approach encourages users to operate this application in a secure, updated environment. Nonetheless, I provide the ability to tweak certain build options (usually without altering the source code) to ensure compatibility with older platforms.Please be aware: Starting from this version, I will not be bundling .deb packages with binary releases due to download limitations and the significant time investment required for packaging. However, you still have the option to compile and package your own .deb.Enhanced Compatibility with macOS Apple Silicon: This update has been meticulously optimized to fully support macOS's M1/M2 chips. I have personally verified the performance and functionality on actual hardware. Consequently, the "x86_64" identifier will no longer appear in the name of macOS binary releases.What's Changed
