We are extremely proud to announce Installer 5 release candidate 1.
As of today, Installer uses a special implementation of APT. This means that dependency, conflicts, versioning, provides, replaces are all handled by APT, and thus should run without any unforeseen errors. Because of this, Installations, removals and very soon downgrades should run without any issues whatsoever (other than the issues you'd also have on other package managers)

Why did we initially launch without APT?

Installer's main goal was always to have a package manager specifically built for iOS & using native code. From the very first version of Installer, released in 2007, to the early beta of Installer 5, released in August this year. The build you have been using until today did not use APT at all. All package management calculations were done by native ObjC code we wrote ourselves. While it worked great for most cases, there was the odd case were it would simply fail, especially with nested dependencies or conflicts.
While trying to fix these bugs, we decided that it was inefficient and the bugs were not solved quick enough. To add to that, we had to prepare a release for Checkra1n. We decided to look at the feasibility of implementing APT.

We always tried to avoid using APT, as has several downsides, especially with speed. As most of you know, Installer is ridiculously fast, in fact, it is the fastest package manager that has ever been for iOS. (See below) However speed is worthless if the installation method is not always reliable.
We eventually decided upon implementing a sandboxed APT environment. As a result of this method, we were able to retain our own methods for downloading the packages & indexing them in the database, and use APT only for the areas where it excels.

What does this mean for Installer?

Installer is now very stable in terms of package management, which, you know, is kinda nice for a package manager :)
Installer should still be just as fast as before. Installation may be a fraction slower however it is stable.
We as a team can now work on other things, such as improving performance even further, implementing new features (3 of which will be groundbreaking), and working on our other projects which had been placed on the back-burner until now.

Does this mean the APT-less version of Installer is dead?

No. Well at least, not for now. We will evaluate this build over a long period, and merge all changes to the master branch in the APT-less branch. We will likely fix the installation (mostly nested conflicts & dependency) issues for the APT-less version. There could still be a situation where the APT-less version is better suited or even required, especially for future jailbreaks for devices not covered by the Checkm8 bootrom exploit.

We hope you are just as excited as we are about this change!
You can download the new version of Installer at our discord if you apply for the beta tester role.

Update on RC1
Yesterday our beta testers on discord (see post above) started testing RC1.
The results were overwhelmingly positive, with most users reporting vastly improved stability & performance.

During testing, our users discovered 3 bugs which we intend to fix before release.

Bugs to be fixed before release
  1. [Cause known] [Currently working on the fix] Crash during initial setup.
  2. [Cause known] [Currently working on the fix] Rare crash when queueing packages.
  3. [Cause not known] One user reported an Issue where Installer could not find the packages it was tasked to Install, possibly due to a logic error where some repositories are not parsed correctly.
Causes of the bugs
The cause of issue #1 & #2 is known and should be fixed relatively quick. The third issue is a bit harder to fully narrow down seeing how it's very rare. We will be testing with the user in question and hope to solve the issue within a few hours.

Help us test
If you want to help us test before we release the build to the public, feel free to join our discord (link in the main post) and apply for the beta tester role.
Please note, only apply for the beta tester role if:
- You have Cr4shed installed
- You know how to share crash logs
- You know how to report bugs
