Release 0.90.0

Tag 0.90.0-RC1

This release candiate is for a new stable series.

Release 0.88.1

This maintainance release fixes duplicates in the job
queues for pending ways and relations, minor compiler
errors, and updates memory usage documentation.

The duplicates in job queues (osm2pgsql-dev#419) only impacted
multithreaded updates and was not observed in most
cases.

Release 0.88.0, a new stable branch

If upgrading and using a database created with 0.86.0 or earlier,
the schema migrations in docs/migrations.md are required.

Major changes since 0.86.0

- Osm2pgsql is now C++ and requires the Boost libraries

- A new backend has been added, the “multi” backend. This allows
  multiple tables which can each contain different types of features.
  More documentation is available at docs/multi.md

- In-database pending way tracking has been replaced with in-memory
  tracking, offering significant performance gains.

- Rendering tables are ordered by GeoHash when created, resulting in
  significant performance improvements.

- z_logic has been improved, taking into account more recent work
  across multiple styles.

- The node storage has been improved, and out of order nodes and
  nodes at 0,0 should now always be handled correctly

- A new test suite with unit tests

- Many bug-fixes

Release a new dev release

Changes since 0.87.2 include

- C++ cleanups
- Fix lockfree queue implementation so --without-lockfree is no longer required
- Convert tags to std::vector
- Fix multi-backend node cache and tag processing

0.87.2 is a development release. Changes since 0.87.1 include
