Great news! The 4.6.0 public release is going live later this week. When that happens, the default Unity version will become 4.6.x.

Subsequent releases of 4.6.x will be handled by Sustained Engineering through the usual process of weekly patch and monthly public releases. The first patch (4.6.0p1) will be released on December 4, and the first public version (4.6.1) will be released soon after.

The following summarises the 4.5.x to 4.6.x transition plan and which version is going to contain what fix:

  • Unity 4.5.5 (released on October 13 2014) will be the last public release version of Unity 4.5.x.

  • All bugs fixed and released in 4.5.5p1 to 4.5.5p5 will be available in 4.6.0p1 and subsequently in  4.6.1.

  • In addition, a few other issues including iOS 8 autorotation are in the works and will be included in 4.6.0p1 and hence in 4.6.1.

  • The first patch release (4.6.0p1) will be shipped on December 4.

  • The first public release (4.6.1) will go live soon after 4.6.0p1.

  • Note that 4.6.0 will use the Web Player released in 4.5.5. New updates to the Web Player (including the OSX 64-bit plugin) will be available in 4.6.1. This version will also be available for automatic updates.

  • Technically, all bugs fixed with Milestones 4.5.6 on the Issue Tracker should be considered as fixed in 4.6.1 as there will not be any 4.5.6 public release.

  • Future 4.5.5 patches will be released only when the need arises – e.g. serious issues affecting wider community and/or to honor existing support contracts.

  • More importantly, iOS 64-bit support will be available in a future 4.6.x release. Learn more

In summary, anyone who would like to ship games with Web Player support with bugs fixed in 4.5.5p1-4.5.5p5 should wait for the 4.6.1 public release. This will be shipped soon after 4.6.0p1. Note that 4.6.0 does not include fixes from the patches 4.5.5p1-4.5.5p5. Also due to complications that could arise from shipping two public releases close to each other, it was decided to drop 4.5.6 and do a 4.6.1 public release instead.

  2. We can not use multiple monitor with one graphic card. We used SoftTH is before 4.6.x but we can not use it now. İts very big and urgent problem because we have a lot of product on thr customer has triple monitor.

    In this case we saw a screen selection menu on 4.6 we want to disable screen selection and use SoftTH for triple monitor with one display card. Because of this problem we downgrade our version to 4.5.5

    is there any solution for this problem ?

  3. Hi,
    4.6.1 does not supported ios 64bit?

    P/s: Sorry my english is not good :D

  4. why dose the CharacterController2D not work?? is that bug? or did you change it?

  5. When will the stable version of 5 start rolling out?

  6. Thankyou, info like this really helps teams in the middle of shipping projects!

  7. Hopefully this is the start of roadmaps and being more open :)

  8. Since it will use the v4.5.5 web player initially, will Unity GUI items work in the web player, or should we wait for v4.6.1?

    1. Yes, of course new UI will work.

      To clarify the blog post a bit: The 4.6.0 webplayer is based off of 4.5.5f1, so changes done in 4.5.5pX (which came after 4.5.5f1) will not available for the 4.6.0 webplayer. 4.6.0 content is just fine.

  9. That’s great, glad to hear it and thanks for the update!

    I suppose there is no ETA on Unity 5 yet? I’ve been waiting for that just because of changes like IL2CPP and the operator overloading changes (along with everything else of course!)

    Thanks!

  10. Have you guys decided on how you will do pull requests for the UI Contributions ? Or is this the last word on the topic?

    Per BitBucket UI Repo

    Will you be taking pull requests?
    At this stage the UI system is undergoing further development internally with many design decisions still being debated and implemented. Also, we are waiting to see the volume of pull requests and the time it will take the process them. As such, we are prioritizing first bug fix pull requests and will iterate on this process going forward.

  11. BOOM! Incredible news! Thanks kicking so much ass on this update, team Unity. :)

      Fixed.

      1. To bylo rychlé. Děkuji :)

  15. In addition, a few other issues including iOS 8 autorotation are in the works and will be included in 4.6.0p1 and hence in 4.6.1.

    Will that fix the issue that causes the Loading screen on iPhone 6 and 6+ to appear flatted? That would be great!

  16. Looking forward to it, I have the RC2 beta and like the canvas UI system quite a bit.

  17. Thanks for the update, good news!
