Google Play Services

Google Play Services has been updated to version 7.3.29-1866531 for lollipop base gapps.

Lollipop Base Gapps package for 5.0.2: gapps-502-base-20150422-1-signed.zip

Lollipop Base Gapps package for 5.1.0: gapps-510-base-20150422-1-signed.zip

Note: The source code of the update-binary (the program that executes the installation script) has been updated in these base gapps packages above. Please let me know if this solves any installation issues that have been reported with certain devices. The gapps packages provided in this thread have been using the same update-binary that is provided by the official Cyanogenmod gapps packages, but upon further investigation, the update-binary in the official Cyanogenmod gapps packages seem to be outdated, which is why I wanted to test if the newer version of update-binary fixes any of the reported installation issues.

Note2: I will update Google Play Services for kitkat base gapps as soon as all of the files are available to create an installation package.
