New Features

• The bootstrapping algorithm has been completely redesigned. The software can now launch directly without requiring TS Preloader. As part of this change, the startup splash screen displayed during initialization has been removed. In addition, spikes in CPU usage have been eliminated, resulting in a more stable architecture with significantly lower memory consumption.
• The Secure Password Generator has been enhanced to consistently satisfy all password complexity requirements, including uppercase and lowercase letters, numbers, and special characters, with every generated password.
• A user-friendly error reporting system has been integrated into Astel's encryption and decryption module. As a result, potential errors are now presented in a clearer and more understandable manner, making troubleshooting significantly easier.
• The import system has been completely redesigned. When importing or dragging and dropping ".astel" or ".csv" files, Astel now detects existing data and offers two options: Merge or Overwrite. With the Merge option, existing records are analyzed and only missing entries are imported, while duplicate records are automatically skipped. With the Overwrite option, all existing data is cleared before the new data is imported.
• The Add Password workflow has been improved. When attempting to add a password for a service that already contains the same Email Address or Username, users are now warned before the entry is created, preventing duplicate records and helping maintain data integrity.
• A new selection control system has been introduced to improve usability. Pressing the ESC key while any item is selected now instantly clears the current selection, providing a faster, cleaner, and more efficient user experience.
• The TS Custom Controls module has been updated to v26.7. Thanks to the new custom controls, all Türkaysoft applications now offer a more modern and consistent user interface aligned with Windows 11 design standards.

Bug Fixes

• A critical cryptographic issue that could cause import operations from "*.astel" files to fail has been resolved.
• A logic flaw and security vulnerability in the Secure Password Generator have been fixed. Under certain conditions, the issue could cause the leading characters of generated passwords to remain unchanged across multiple generations.
• A critical issue affecting the Overwrite option during data imports has been fixed. Previously, when existing data was detected, selecting Overwrite could cause records to be appended repeatedly instead of replacing the existing data. The import process now correctly clears existing records before importing new data.
• Several issues within the CSV processing infrastructure have been resolved. Full compatibility has been added for Windows (\r\n), legacy (\r), and standard (\n) line-ending formats, ensuring reliable processing of CSV files created on different platforms. The escaping and quotation-handling mechanisms have also been redesigned, significantly improving stability and accuracy when parsing quoted data. In addition, optimizations to the text generation infrastructure have improved overall CSV processing performance.
• A selection management issue that caused the first row in the list to be automatically reselected after deleting an entry has been fixed. This improvement provides a more consistent and predictable user experience following delete operations.
• An issue that could result in an unwanted blank line being added to the end of exported CSV files has been resolved.
• A bug that prevented the Desktop directory from being selected as the default location during CSV export operations has been fixed.

Changes

• The password length generated by the Secure Password Generator has been adjusted to a range of 12–16 characters.
• The symbol sets used across all password generation modes within the Password Generator have been updated to improve compatibility across different systems and applications.
• The Donation page can now be accessed using the CTRL + Alt + D keyboard shortcut.
• [TS Updater] Before the update process begins, users are now prompted to choose whether they would like to view the release notes.

New Features

• Session data is now encrypted using DPAPI (Windows Data Protection API). As a result, the data can only be decrypted by the same user account on the same machine. This restriction does not apply to manually backed-up data.
• The PBKDF2-HMAC-SHA512 mechanism used to protect against brute-force attacks has been strengthened with 210,000 iterations and salt-based key derivation.
• Data masking and reference-clearing techniques have been improved to provide additional protection against memory analysis and shoulder-surfing attacks.
• The password generation engine has been completely redesigned. The cryptographically secure "RandomNumberGenerator" now replaces "System.Random". Rejection Sampling has been implemented to eliminate modulo bias, while the Fisher–Yates Shuffle algorithm enhances character randomization security. Passwords are guaranteed to contain at least one uppercase letter, one lowercase letter, one digit, and one symbol. The random password length range has also been increased to 10–18 characters.
• An automatic clipboard clearing feature has been added for copied passwords. If no other content is copied within 30 seconds, the password is automatically removed from the clipboard.
• Password data is now displayed in a masked (●) format within the table. This provides an additional layer of protection against screenshots and other visual information disclosure methods. The display mode can be switched between plain text and masked view using the Password Masking option in the top menu.
• Memory security has been improved. ClearSecureTextBox now removes unnecessary references to sensitive data from memory.
• A SemaphoreSlim-based locking and timeout mechanism has been added to prevent thread race conditions.
• A validation algorithm has been introduced for both new record creation and existing record updates. Duplicate records can no longer be added, and unnecessary update operations are prevented when no actual changes have been made.
• You can now navigate between records using the Up and Down arrow keys, significantly improving usability.
• The TS Preloader loading bar has been rebuilt using our modern TS Custom Controls graphics library, developed entirely in-house. As a result of this infrastructure upgrade, the loading bar now features smooth rendering and rounded corners that align with the visual style of Windows 11.
• [TS Updater] A new validation algorithm has been added to check whether the target application is currently running before the update process begins.

Bug Fixes

• Stability issues related to the automatic backup system have been resolved. A maximum limit of 30 backups has been introduced. Timestamped file names are now used to prevent naming conflicts. Concurrent backup operations are serialized through a locking mechanism, and a 5-second timeout has been added to prevent potential waiting issues during backup cancellation.
• Fixed an issue in TS Preloader where the password visibility state on the login screen was not reset to a valid value when an invalid state was detected.
• Resolved a condition that could prevent TS Preloader from shutting down safely during rare application crash scenarios.
• [TS Updater] Fixed an issue that could prevent the updated application's executable "*.exe" file from being located after the update process.
• [TS Updater] Fixed a bug that could leave outdated "*.sha256" files in the application directory after an update.
• [TS Updater] Fixed a rare issue that could cause subfolders to be moved into the root directory after an update.
• [TS Updater] Fixed an issue during the first launch that could cause flickering and a temporary white window appearance due to Windows Defender interactions.

Changes

• The confirmation dialogs displayed by the Update and Delete buttons now provide more detailed information, helping to prevent accidental data loss.
• The automatic backup system has been redesigned to keep disk usage under control.
• The service list has been simplified for a cleaner and more streamlined experience.
• A small improvement has been made to the internet connectivity detection algorithm. Connectivity checks are now performed in the background with minimal impact on the user interface thread.
• The keyboard shortcuts in the top menu have been reorganized and simplified to provide a consistent experience across all Türkaysoft applications and to avoid potential conflicts with standard Windows shortcuts.
• The TS Preloader splash image has been updated with a Türkiye-themed stadium design to celebrate Türkiye's qualification for the 2026 FIFA World Cup—its first appearance in 24 years. Congratulations, Türkiye!
• The TS Custom Controls module has been updated to version 26.6, delivering improved stability and a more polished visual appearance.
• [TS Updater] The application icon has been redesigned to provide a more modern and refined look.

New Features

• A built-in update system has been integrated into Astel. New versions can now be updated directly from within the application without the need to manually download them from GitHub or the website. The update component is included in the package as TSUpdater.exe. When a new version is released, you will receive a notification; by selecting "Yes", you can open the update tool to view the release notes and start the update.
• The key generation system has been strengthened. The old method was removed and replaced with a more secure and modern architecture. Encryption and authentication keys have been completely separated. This has enhanced protection against brute-force and key-guessing attacks.
• Protection against timing-based attacks has been added. Plaintext comparisons during login and password change operations have been removed. Instead, a secure comparison method that operates in a fixed time has been implemented. This prevents attacks that attempt to extract data by analyzing transaction durations.
• Memory security has been improved. After encryption and decryption operations are completed, sensitive data is automatically cleared from memory. This reduces the risk of data extraction through memory scanning.
• The internet connection and update checking infrastructure have been rewritten to meet modern standards. The system now operates in a more up-to-date, stable, and reliable manner.
• The TSImageRenderer and ResizeImageToDeviceDpi algorithms have been updated. The image processing and resizing processes have been optimized to provide a structure that delivers sharper results and more efficient memory usage.

Bug Fixes

• The distribution error in random text generation has been fixed. The issue that caused certain characters to be selected less frequently than others has been resolved. All characters are now generated with equal probability.
• The risk of file corruption has been reduced. Saving operations have been made more secure. Data is first created temporarily and then modified securely. This reduces the risk of data loss in the event of sudden shutdowns or crashes.
• In the internet connection check, an issue that caused the system to detect "no connection" even though internet access was available due to the connection endpoint has been resolved.
• In the update check algorithm, a cache-related issue that caused the system to report "no updates found" even when a new version was available has been fixed.
• Flickering and image distortion occurring during interface transitions and page scrolling on high-refresh-rate monitors have been fixed.
• Interface flickering that occurred during theme changes has been resolved.

Changes

• Our brand and distribution name have been updated. We are now operating under the name Türkaysoft. This means our website is now turkaysoft.com.
• The session security system has been simplified. Unnecessary dependencies have been removed, and the architecture has been made more stable. Since session data is already stored in a user-specific protected folder, the additional layer of protection has been simplified.
• Encryption settings have been clarified. The security parameters used during registration and setup have been clearly defined and strengthened.
• All dimension calculation algorithms have been updated to be compatible with Windows’ current calculation methods; results are now more consistent and standardized.

Removed Features

• The TS Wizard integration has been removed because it was not sufficiently functional and was not being used.
