The latest releases of TextMesh Pro for Unity 4.6 and Unity 5 are available on the Asset Store. (Short answer) because it can take between 7 to 14 days for new releases to get approved on the Asset Store and when Unity releases a new version of Unity like Unity 5.2 which isn't as stable as previous releases, it doesn't make sense to update the Asset Store release until Unity that particular release of Unity becomes more stable. (Longer answer) When Unity releases new versions of their product like Unity 5.2 where a significant part of their API changes coupled with the introduction of a larger than usual amount of bugs for which we will have to wait several weeks for them to fix which indirectly will require me to potentially release several new versions of TextMesh Pro to handle these Unity bugs and changes, it is a lot more efficient for me to release these new version to the user forum since I can get those version in the hands of my user much faster since it can take between 7 to 14 days for new releases to get approved by Unity for the Asset Store. Going forward, I will always release new versions of TextMesh Pro on the user forum first. Then unless some issues are reported by my users, I will proceed to update the Asset Store releases within the following 7 to 10 days. That is provided we are dealing with a somewhat stable version of Unity. When we are dealing with some new release of Unity which introduced a larger than usual amount of bugs (like in the case of Unity 5.2) then it will take longer for the new versions of TextMesh Pro to make it to the Asset Store. Every TextMesh Pro user should register to the user forum. Approval only take a few minutes to a few hours if I am sleeping or if there is an issue with the invoice # provided by the user. Access to the user forum isn't just for getting those new releases, it is the best place to request support and to also get access to example scripts.
